| Derivative Instruments and Hedging Activities Disclosure [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Financial Instruments | 6. Financial Instruments Natural Gas Contracts Periodically, we enter into certain forward natural gas contracts or volume purchase commitments, which are derivatives. We utilize these natural gas contracts as economic hedges for risk management purposes, but the contracts are not designated as hedging instruments. At June 30, 2026 and December 31, 2025, we had no outstanding forward natural gas contracts or volume purchase commitments accounted for as derivatives. When present in the past, the valuations of the natural gas contracts were classified as a Level 2 fair value measurement. Financial Instruments At June 30, 2026 and December 31, 2025, we did not have any financial instruments with fair values materially different from their carrying amounts (which excludes issuance costs, if applicable) except for our Senior Secured Notes. Fair value of our Senior Secured Notes is classified as a Level 2 fair value measurement while the treasury securities that comprise our short-term investments are a Level 1 fair value measurement. The fair value of financial instruments is not indicative of the overall fair value of our assets and liabilities since financial instruments do not include all assets, including intangibles, and all liabilities.
