ok. its cool. aside from my assumptions, my main concern is still health. glass is always going to be better. idk why its even an argument in the first place. it should be common knowledge at this point.
Glass is obviously a million times better than plastic in every way possible, but there isn't anything wrong with plastic as long as you're not lighting it on fire.
I know this is a mega necro-post, but you sir inspired me. I built a glass version of this and will get a video/pics up soon.
