Smoke smooth The Ash Catcher Glass Pipe is so named because of the indented mouthpiece. One of many Chameleon Glass innovations, first available in early 2002, this was one of the first! By indenting the mouthpiece, anything heavier than air (ash, particulate or any solids) is pulled down by the natural effect of gravity, misses the mouthpiece hole and is deflected further downward to collect at the base of the indent. Chameleon Glass is one of the most well known and respected American Glass companies. They are most popular for their hand pipes, bubblers, and accessories dating back as far as 1991. Located in Arizona, all pieces are 100% American made. Chameleon Glass is always creating new and innovative designs to bring fresh new products to the market.
