Lexan. Just to be sure... Answered
So, I was thinking about an Halloween mask, a steampunk diving dress. The most complex thing is, of course, the head piece. More specifically, I'm in a bit of a quandary with the visor: I need to make a convex, ellyptical dome of clear plastic. Since I need to fit that into a frame I need to make it from flat panels; this way I'll get the shape I want. I think I'll use Lexan: it seems to be quite sturdy and easy to work on. In theory, all I have to do is heat the thing up to 200Â°C (400Â°F) and it will bend like a charm, but I'm a bit worried about exalations and whatnots; can someone help me here please?
