Can anyone suggest a source for a glass cylinder in the neighborhood of 8" diameter by 12-18" long, with fairly heavy walls (~1/4" or more), either quartz or soda glass? I could tolerate minor defects in case you know of a good source for surplus, rejects, or leftovers. (The latter are called "drops" when referring to metal, but I wonder if that term has a different connotation when talking about glass?) Thanks.
