| Business Description and Basis of Presentation [Text Block] |
Liquidmetal Technologies, Inc. (the “Company”) is a materials technology and manufacturing company that develops and commercializes products made from amorphous alloys. The Company’s family of alloys consists of a variety of bulk alloys and composites that utilizes the advantages offered by amorphous alloys technology. The Company designs, develops, manufactures and sells products and custom parts from bulk amorphous alloys to customers in a wide range of industries. The Company also partners with third -party manufacturers and licensees to develop and commercialize Liquidmetal alloy products.Amorphous alloys are, in general, unique materials that are distinguished by their ability to retain a random atomic structure when they solidify, in contrast to the crystalline atomic structure that forms in other metals and alloys when they solidify. Liquidmetal alloys are proprietary amorphous alloys that possess a combination of performance, processing, and potential cost advantages that the Company believes will make them preferable to other materials in a variety of applications. The amorphous atomic structure of bulk alloys enables them to overcome certain performance limitations caused by inherent weaknesses in crystalline atomic structures, thus facilitating performance and processing characteristics superior in many ways to those of their crystalline counterparts. The Company’s alloys and the molding technologies it employs results in components that exhibit: exceptional dimensional control and repeatability that rivals precision machining, excellent corrosion resistance, brilliant surface finish, high strength, high hardness, high elastic limit, alloys that are non-magnetic, and the ability to form complex shapes common to the injection molding of plastics. Interestingly, all of these characteristics are achievable from the molding process, so design engineers do not have to select specific alloys to achieve one or more of the characteristics as is the case with crystalline materials. The Company believes these advantages could result in Liquidmetal alloys supplanting high-performance alloys, such as titanium and stainless steel, and other incumbent materials in a wide variety of applications. Moreover, the Company believes these advantages could enable the introduction of entirely new products and applications that are not possible or commercially viable with other materials.The Company’s revenues are derived from i) selling bulk Liquidmetal alloy products to customers who produce medical devices, automotive assemblies, sports and leisure goods, and non-consumer electronic devices, ii) selling tooling and prototype parts such as demonstration parts and test samples for customers with products in development, iii) product licensing and royalty revenue, and iv) research and development revenue. The Company expects that these sources of revenue will continue to significantly change the character of the Company’s revenue mix. |

| Basis of Presentation and Significant Accounting Policies [Text Block] |
The accompanying unaudited interim consolidated financial statements as of and for the three months ended March 31, 2019 and March 31, 2018 have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information and in accordance with the instructions to Form 10 -Q. Accordingly, they do not include all of the information and notes required by US GAAP for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring accruals) considered necessary for a fair presentation have been included. All intercompany balances and transactions have been eliminated in consolidation. Operating results for the three months ended March 31, 2019 are not necessarily indicative of the results that may be expected for any future periods or the year ending December 31, 2019. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company's 2018 Annual Report on Form 10 -K filed with the Securities and Exchange Commission (“SEC”) on March 5, 2019. Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update which modifies the accounting for leasing arrangements, particularly those arrangements classified as operating leases. This update will require entities to recognize the assets and liabilities arising from operating leases on the balance sheet. The Company adopted the requirements of this guidance as of January 1, 2019, utilizing the modified retrospective approach. Due to the Company not having any qualifying lease obligations, the adoption of this guidance did not have any impact on the Company’s consolidated financial statements.Liability Classified Warrants In July 2017, the FASB issued an accounting standards update which modifies the requirements for the classification of certain financial instruments with down round features as equity versus liabilities. The guidance will allow for financial instruments previously required to be presented as liabilities due to the presence of down round features to be presented as equity upon meeting other criteria. The Company adopted the requirements of this update effective as of January 1, 2019, utilizing the full retrospective transition option. Accordingly, the Company reclassified the warrant liability to additional paid in capital on its December 31, 2018 consolidated balance sheets, which increased additional paid-in capital by $6,970, increased accumulated deficit by $4,778, and decreased warrant liability by $2,192. In addition, because of the retrospective adoption, the Company credited change in fair value of warrant liability on its consolidated statements of operations by $1,267 for year ended December 31, 2018. The change in fair value of the warrant liability was offset by a $1,267 credit to accumulated deficit on the consolidated balance sheets. Similarly, the Company credited change in fair value of warrant liability on its consolidated statements of operations by $275 for three months ended March 31, 2018. The adoption of this guidance had no impact on the Company’s consolidated statement of cash flows in the current or previous interim and annual reporting periods. The following table provides a reconciliation of warrant liability, additional paid-in capital, accumulated deficit, and change in fair value of warrant liability on the consolidated balance sheets for the year ended December 31, 2018 and the three -months ended March 31, 2018 ( in thousands):
Fair Value Measurements The estimated fair values of financial instruments reported in the consolidated financial statements have been determined using available market information and valuation methodologies, as applicable. The fair value of cash and restricted cash approximate their carrying value due to their short maturities and are classified as Level 1 instruments within the fair value hierarchy.Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value based upon the following fair value hierarchy:
Other recent pronouncements Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants and the SEC did not or are not believed by management to have a material impact on the Company's present or future consolidated financial statements. |

Manufacturing Facility Purchase On February 16, 2017, the Company purchased a 41,000 square foot manufacturing facility located in Lake Forest, CA, where operations commenced during July 2017. The purchase price for the property was $7,818. 2016 Purchase Agreement On March 10, 2016, the Company entered into a Securities Purchase Agreement (the “2016 Purchase Agreement”) with Liquidmetal Technology Limited, a Hong Kong company (the “Investor”), which is controlled by the Company’s Chairman and CEO, Professor Lugee Li (“Professor Li”).

The 2016 Purchase Agreement also provided that, with certain limited exceptions, if the Company issues any shares of common stock at any time through the fifth anniversary of the 2016 Purchase Agreement, the Investor will have a preemptive right to subscribe for and to purchase at the same price per share (or at market price, in the case of issuance of shares pursuant to stock options) the number of shares necessary to maintain its ownership percentage of Company-issued shares of common stock.Eontec License Agreement On March 10, 2016, in connection with the 2016 Purchase Agreement, the Company and DongGuan Eontec Co., Ltd., a Hong Kong corporation (“Eontec”), entered into a Parallel License Agreement (the “License Agreement”) pursuant to which the Company and Eontec agreed to cross-license their respective technologies. The Company’s Chairman and CEO, Professor Li, is also a major shareholder and Chairman of Eontec.The License Agreement provides for the cross-license of certain patents, technical information, and trademarks between the Company and Eontec. In particular, the Company granted to Eontec a paid-up, royalty-free, perpetual license to the Company’s patents and related technical information to make, have made, use, offer to sell, sell, export, and import products in certain geographic areas outside of North America and Europe. In turn, Eontec granted to the Company a paid-up, royalty-free, perpetual license to Eontec’s patents and related technical information to make, have made, use, offer to sell, sell, export, and import products in certain geographic areas outside of specified countries in Asia. The license granted by the Company to Eontec is exclusive (including to the exclusion of the Company) in the countries of Brunei, Cambodia, China (P.R.C and R.O.C.), East Timor, Indonesia, Japan, Laos, Malaysia, Myanmar, Philippines, Singapore, South Korea, Thailand, and Vietnam. The license granted by Eontec to the Company is exclusive (including to the exclusion of Eontec) in North America and Europe. The cross-licenses are non-exclusive in geographic areas outside of the foregoing exclusive territories. Beyond the License Agreement, the Company collaborates with Eontec to accelerate the commercialization of amorphous alloy technology. This includes but is not limited to developing technologies to reduce the cost of amorphous alloys, working on die cast machine technology platforms to pursue broader markets, sharing knowledge to broaden our intellectual property portfolio, and utilizing Eontec’s volume production capabilities as a third party contract manufacturer.During March 2017, the Company signed contracts with Eontec to purchase two hot-crucible amorphous metal molding machines (“Machines”) at a total purchase price of $780. The Machines were delivered to the Company’s new manufacturing facility located in Lake Forest, CA in April 2017 and were operational during the fourth quarter of 2017. Apple License Transaction On August 5, 2010, the Company entered into a license transaction with Apple Inc.

The Company is also obligated to maintain certain limited liability company formalities with respect to CIP at all times after the closing of the license transaction.Other License Transactions On January 31, 2012, the Company entered into a Supply and License Agreement for a five year term with Engel Austria Gmbh (“Engel”) whereby Engel was granted a non-exclusive license to manufacture and sell injection molding machines to the Company’s licensees. Since that time, the Company and Engel have agreed on an injection molding machine configuration that can be commercially supplied and supported by Engel. On December 6, 2013, the companies entered into an Exclusivity Agreement for a 10 year term whereby the Company agreed, with certain exceptions and limitations, that the Company and its licensees would purchase amorphous alloy injection molding machines exclusively from Engel in exchange for certain royalties to be paid by Engel to the Company based on a percentage of the net sales price of such injection molding machines.The Company’s majority-owned Liquidmetal Golf subsidiary has the exclusive right and license to utilize the Company’s Liquidmetal alloy technology for purposes of golf equipment applications. This right and license is set forth in an intercompany license agreement between Liquidmetal Technologies and Liquidmetal Golf. This license agreement provides that Liquidmetal Golf has a perpetual and exclusive license to use Liquidmetal alloy technology for the purpose of manufacturing, marketing, and selling golf club parts and other products used in the sport of golf. The Company owns 79% of the outstanding common stock of Liquidmetal Golf.In June 2003, the Company entered into an exclusive license agreement with LLPG, Inc. (“LLPG”).

The Company, in turn, will receive royalty payments over the life of the contract on all Liquidmetal products produced and sold by LLPG. The exclusive license agreement with LLPG expires on December 31, 2021. In March 2009, the Company entered into a license agreement with Swatch Group, Ltd. (“Swatch”) under which Swatch was granted a non-exclusive license to the Company’s technology to produce and market watches and certain other luxury products. In March 2011, this license agreement was amended to grant Swatch exclusive rights as to watches, but non-exclusive as to Apple, and the Company’s license agreement with LLPG was simultaneously amended to exclude watches from LLPG’s rights. The Company will receive royalty payments over the life of the contract on all Liquidmetal products produced and sold by Swatch. The license agreement with Swatch will expire on the expiration date of the last licensed patent. |

Property and equipment consist of the following:
Depreciation expense for the three months ended March 31, 2019 and 2018 was $258 and $231, respectively. For the three months ended March 31, 2019 and 2018, $23 and $13 of depreciation expense, respectively, was included in cost of sales and $235 and $218 was included in selling, marketing, general, and administrative expenses, respectively.The Company’s manufacturing activities and efforts have historically focused on the identification, design, and successful prototyping of customer applications, including, but not limited to, medical and automotive components. Experience has shown that customers will perform numerous tests and extensively evaluate components and products before incorporating them into their finished products. The time required for testing, evaluating, and designing the Company’s components and products for use in a customer’s products, and in some cases, obtaining regulatory approval, can be significant, with an additional period of time before a customer commences volume production of products incorporating Liquidmetal components and products, if ever. The time it takes to transition a customer from limited production to full-scale production runs will depend upon the nature of the processes and products into which Liquidmetal alloys are integrated.Investments in the Company’s manufacturing capabilities and infrastructure have been historically made based on certain assumptions and expectations regarding the time and investment required to reach minimum volume manufacturing levels, to scale and generate sustainable revenues, and to ultimately reach profitability. As a result of the Company’s inability to gain traction in receiving and fulfilling orders for the volume production of parts, the Company has commenced a comprehensive review of the options available in the context of its current strategy. While no decisions have been made, any change to the current strategy, depending on its nature, may result in future impairments of the Company’s manufacturing assets, inclusive of patents and trademarks. |

| Earnings Per Share [Text Block] |
Basic earnings per share (“EPS”) is computed by dividing earnings (loss) attributable to common shareholders by the weighted average number of common shares outstanding for the applicable period. Diluted EPS reflects the potential dilution of securities that could share in the earnings. Options to purchase 27,531,332 shares of common stock, at prices ranging from $0.07 to $0.38 per share, were outstanding at March 31, 2019, but were not included in the computation of diluted EPS for the same period as the inclusion would have been antidilutive, given the Company’s net loss. Warrants to purchase 10,066,809 shares of common stock, with a price of $0.07 per share, outstanding at March 31, 2019, were not included in the computation of diluted EPS for the same period as the inclusion would have been antidilutive, given the Company’s net loss.Options to purchase 33,334,035 shares of common stock, at prices ranging from $0.07 to $0.47 per share, were outstanding at March 31, 2018, but were not included in the computation of diluted EPS for the same period as the inclusion would have been antidilutive, given the Company’s net loss.

| Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Lessee, Leases [Policy Text Block] | Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update which modifies the accounting for leasing arrangements, particularly those arrangements classified as operating leases. This update will require entities to recognize the assets and liabilities arising from operating leases on the balance sheet. The Company adopted the requirements of this guidance as of January 1, 2019, utilizing the modified retrospective approach. Due to the Company not having any qualifying lease obligations, the adoption of this guidance did not have any impact on the Company’s consolidated financial statements. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Adoption of New Accounting Pronouncements [Policy Text Block] | Liability Classified Warrants In July 2017, the FASB issued an accounting standards update which modifies the requirements for the classification of certain financial instruments with down round features as equity versus liabilities. The guidance will allow for financial instruments previously required to be presented as liabilities due to the presence of down round features to be presented as equity upon meeting other criteria. The Company adopted the requirements of this update effective as of January 1, 2019, utilizing the full retrospective transition option. Accordingly, the Company reclassified the warrant liability to additional paid in capital on its December 31, 2018 consolidated balance sheets, which increased additional paid-in capital by $6,970, increased accumulated deficit by $4,778, and decreased warrant liability by $2,192. In addition, because of the retrospective adoption, the Company credited change in fair value of warrant liability on its consolidated statements of operations by $1,267 for year ended December 31, 2018. The change in fair value of the warrant liability was offset by a $1,267 credit to accumulated deficit on the consolidated balance sheets. Similarly, the Company credited change in fair value of warrant liability on its consolidated statements of operations by $275 for three months ended March 31, 2018. The adoption of this guidance had no impact on the Company’s consolidated statement of cash flows in the current or previous interim and annual reporting periods. The following table provides a reconciliation of warrant liability, additional paid-in capital, accumulated deficit, and change in fair value of warrant liability on the consolidated balance sheets for the year ended December 31, 2018 and the three -months ended March 31, 2018 ( in thousands):

| Fair Value Measurement, Policy [Policy Text Block] | Fair Value Measurements The estimated fair values of financial instruments reported in the consolidated financial statements have been determined using available market information and valuation methodologies, as applicable. The fair value of cash and restricted cash approximate their carrying value due to their short maturities and are classified as Level 1 instruments within the fair value hierarchy.Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value based upon the following fair value hierarchy:

| New Accounting Pronouncements, Policy [Policy Text Block] | Other recent pronouncements Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants and the SEC did not or are not believed by management to have a material impact on the Company's present or future consolidated financial statements. |
