Well I was hoping some-one had tried the illusion on dark glass but I guess not.
As far as brown beer bottles, I baked a 12oz and a 40oz tonight at 400F or a bit over, they did not crack. I was working outside in cooler weather, just took the hot bottles out and set them on top of the stove to cool. No problems!
Now to coat some
These test bottle were not coated, just baked to see if they would break, they did not break so later I will try a gloss black or gloss red powder on them. I only have those and yellow, I hate yellow.
I'll try the illusion when I have money to order powder just to play with it. If anyone tries such bottles, dark brown glass, I would like to know how it turns out and any problems shooting them. Since glass won't carry a ground I figure shoot hot, but even coverage and such for a see through illusion? Really wondering if the better more PRO guys can get a decent look, I'm still an amature here you know. LOL
