All scientific, heady, and other glass ashcatchers for waterpipes and other smoking devices available from AllGlass.com

The core idea of an ashcatcher is that it acts as a removable barrier and extra layer of diffusion for your waterpipe or oil rig.

Whenever ash would normally fall into your piece, it instead falls into the ash catcher, which you can then remove and clean separately instead of having to clean your entire pipe. The different types of percs available in ACs also further diffuse the vapor, making each hit just that much smoother.
