Someone gave me a wok. It's black and I scraped through the black coating so the metal is showing. I assume a regular wok (without non-stick coating) wouldn't have a black coating that could be scraped through?
Also I intend to use this wok like a wok. That is, I won't be using it at lower heats that are acceptable for non-stick coatings. My understanding, based on the "2 second google search" is that while this will destroy the non-stick coating (assuming that's what I have?), it's not unhealthy.
So my 2 questions are: How can I know for sure if this has a non-stick coating? Even if it is, am I correct in assuming it won't be unsafe to cook at high heats?
Edit: Here are a couple pictures. The only stamping on the entire Wok is "CHINA".
