I expect something with a lot of small bubbles and cracks, also it also overheated and got weird decomposition and reactions, something like a overcooked/toasted meal. Reusing a comment that I made in a previous thread:
replyFor comparison, there is a nice video by NileRed https://www.youtube.com/watch?v=phNLecfyWS8 He is making Bakelite that is a type of plastic. It's a tiny amount, in a lab, on purpose and he may make a few attempts. Anyway it overheat and instead of a nice piece of plastic he got a nasty block of foam with burned plastic. No imagine a huge tank of a similar chemistry reaction.
A contractor showed me how to fix dents in granite with superglue. It’s totally clear. The trick is to scrape it with a razor blade at a 90 degree angle (strait horizontal). The imperfections become nearly invisible.
replyThis is also how glass chip repair works. If the polymer has a close enough index of refraction to the glass, it's invisible.
replyI've been told this is a cheap way to fix small windshield cracks. Never tried it but sounds like it would work for the small spider sized and shaped cracks from small rock impacts.
replyThis is basically what the glass repair kits sold at auto parts stores are. (They also include a suction cup with syringe, to vacuum any air bubbles out.)
replyAnd, bringing this topic full circle, the chemical in those kits is methyl methacrylate!
replyThe expensive way is superglue plus a little suction cup to evacuate the air, and a razor blade.
