Stuck Again.... Sigh. How do you unstick glass on glass?

Permetex anti-seize. and it works well for spark plugs in aluminium heads...

ohaha

i would give pam a try. seriously. that shit is great.

it's definitely the asian joint. those are the only ones to ever stick without much if any user error, ever.
never ever had to lube joints, never had a problem.

Glass on glass is basically lab glass for some intensive aroma therapy. For lab glass you use vacuum grease. Its an inert silica compound mixture. It costs about $30 a tube but a little goes a long ways. When you run any lab setup with some pressure generated, you see that the glass on glass is not quite a perfect seal. The vacuum grease fixes this. Also your joints don't get stuck. Honestly though since you aren't getting it that hot you could just use petroleum jelly. Vacuum grease lasts a lot longer though.
