Keep your Whisky away from your Flame Polished Acrylic

<< < (4/5) > >>

RandyT:
Looks to me like the stress is created by the heating process, and the alcohol, being a pretty strong solvent, eats into the surface of the stressed area, creating a microscopic path of stress release.  The moment such a path is created, all of the surrounding stresses are channeled to that small area, and it tries to normalize, thus creating the fractures.

Well, off to refill all my empty Jack Daniel's bottles with denatured alcohol.

xefned:
Cool! Now I know how to reproduce an authentic vintage look to my acrylic.   >:D

Yep it's the weekend, party at Jim's house

First off, denatured is fairly high proof. Not sure if whiskey will trigger it, I know beer won't.

Second, before everyone goes off half cocked, do the research. I came across this for a related issue and found posts like this from 2007. Pay attention to the annealing link. In a nutshell, it's fixable.... Not after the fact of course.

Heat treating your pinball parts isn't worrisome unless you intend to fill your table with moonshine or some such.

note: fixed URL. Sorry about that, I didn't notice it when I posted the first time.....
