Use it to block bottom air vent on my Pit-Barrel-Cooker meat smoker, and save remaining charcoal.

IF you have a 22 Liter pyrex round bottom short neck boiling flask this stopper fits perfectly well and does not contaminate the wort like the nasty rubber stoppers. This meets the pyrex #14 stopper spec.

The silicone cuts down on the electrical charge and you have to go heavy on the rim. Two color jobs are moor difficult because the rim will not heat up the same as the rest of the cup.
