When it comes to choosing cookware, ovenproof is a crucial feature to consider. But there are several other words that can be used to describe cookware that can stand up to high temperatures. One alternative is heat-resistant, which implies that the cookware can withstand heat without damage. Another synonym is fireproof, which suggests that the cookware can resist fire or flames. Non-flammable and fire-resistant are other similar terms. They imply that the cookware is capable of withstanding high heat without catching on fire. Finally, there's the term oven-safe, which refers to cookware that can be used safely in the oven without harm.
