What is CFL Glass?CFL Glass

CFL glass is a special type of Uranium infused glass that appears to change color when it is exposed to ultraviolet or fluorescent light. It is also known as UV, uranium, or Vaseline glass.

In order to create CFL glass, the glassblower ads small amounts of uranium dioxide to the glass during the melting process. The final product ends up being about 2% Uranium so it poses no health hazards. It contains just enough Uranium to make the glass change color when it is exposed to ultraviolet light.

The color change can be quite drastic. Pieces may look green, champagne colored, or even clear under normal light and then transform into a glowing green, soft rose, or vivid hot pink when exposed to UV rays. For this reason, many glass collectors have started installing black lights at their dab stations.

There are often certain “hype” colors that become extremely coveted and hard to find. Prices on these pieces sometimes skyrocket, and if you are lucky enough to own one they can be worth a lot of money. Some CFL rigs sell for as much as $25,000.

CFL glass is sometimes confused with glow in the dark glass, but it is actually quite different. Glow in the dark glass is created by adding glow powder to the glass. Glow powder contains phosphors which become radiant after being exposed to a light source.

Is it New?

CFL glass has actually been around for quite a while. It was very popular in the early 20th century when it was used extensively to make tableware and various other household items. In fact, between 1950 and 1980 more than four million uranium glass pieces were created in America. It was originally desired for its yellow and green coloring. Back then, the glass could be as much as 25% Uranium and was therefore somewhat radioactive. Knowing what we know now, it’s hard to imagine them making dishes out of it.

During the Cold War, it became increasingly difficult to get uranium, and the production of CFL glass dropped off exponentially. It never regained popularity until recently, when it started gathering a strong following in the smoking industry.

Today CFL glass is used to make fantastic color changing rigs and heady bongs, which are as much a piece of art as they are a smoking utensil.
