What is the highest temperature the ink from sharpie markers should be heated to? Answered
I need to use some kind of ink for a project that will be heated to around 400 degrees F (~200C). I was wondering if it is safe to use sharpies at these temperatures. The pen won't be heated up. Just the ink. Some kind of technical sheet would be helpful but any info you have is nice too. And also if anyone has ideas about other easily accessible high heat resistant inks then that would be awesome.
