A Brief History
Although it seems like it’s pretty tough to buy a pipe these days that’s not color changing, it wasn't until around the 1980’s when a well known glass blowing artisan Bob Snodgrass accidentally discovered that coating a pipe or bong with silver or gold fumes would cause the it to gradually change colors, opening up a whole new world for the glass blowing industry.
How it Works
A metal alloy is vaporized to create a fume that the glass is rotated in until a visible layer of the vaporized metal is on the surface of the pipe. After this, another layer of glass is added to encase the metal between the two layers. The pipe appears to change colors because the metal alloy inside of it contains very lightly colored ions. Over time, resin builds up behind the thin layer of ions, creating a dark background which, in contrast, makes the ions’ colors much more visible. Once the pipe is cleaned, the ions again become nearly invisible and you can begin the color changing journey all over again.
How to Tell if a Piece is Color Changing
Normally, glass will have a very clean, transparent appearance. However, if a piece is color changing, it will appear slightly translucent or foggy. Usually, a color changing pipe or bong will have a yellow, blue, or pinkish tint to the glass. That light shade is what will change colors as resin builds inside of the pipe, creating a beautiful and completely unique piece for you to enjoy.
