Looking for a cheap, available source for glass pipe, approximately 1 inch in diameter and at least several feet long. Borosilicate glass would be ideal.
One thought on this (Which I know everyone is going to freak out at...) is to cut florescent tubes at each end, and use a solvent on the phosphor layer. It seems like a bad idea because of the mercury issue, although sources indicate that about 99% of the mercury is bonded with the phosphor layer. I'm also not sure what type of glass a florescent tube is, exactly.
A commercial source would be nice, but I haven't found anything that would cost a solid $100 for a 3-4 foot chunk.
Thoughts?
Edit: On a side note; finding "glass pipe" for sale on the internet tends to lead to online head shops.
