High Heat Non-toxic Pearlescent Glass Pigments.

 

What are high heat pearlescent glass pigments: These are very specialized pigments that are used in the glass industry to color glass under high heat conditions. These specific pearlescent pigments we carry are new to the lampworking industry. Although some of the compounds found in these pigments have always been used to color glass, the pearlescent characteristic is new. Pearlescent pigments have been around a long time, but normally do not work with high heat. We had special formulas produced that now work with extremely high heat. These pigments are very easy to use, and add a wonderful semi-gloss iridescence to the outside of your glass. The final bead or other glass item you make will change color depending on the direction of the light. Please refer below for complete easy instructions on how to use these pigments.

 
Abalone Pearlescent Glass Pigment. These are very light pigments, so the 10 gram baggie they come in will go a very long way. $11.95/ 10grams (1/3 ounce).
   
   
Mother-of-Pearl Pearlescent Glass Pigment. These are very light pigments, so the 10 gram baggie they come in will go a very long way. $11.95/ 10grams (1/3 ounce).
 
Abalone Pearlescent Glass Pigment. Mother-of-Pearl Pearlescent Glass Pigment.

There is no real Abalone or Mother-of-Pearl shell in these pigments. Those names are only used to describe the color.

 

Directions for using Pearlescent Glass Pigment:

 

Although these pigments are considered safe and non-toxic, always be sure to use proper ventilation with this and all lampworking applications. If you need advice on how to properly ventilate your work area, please send us a note. We would be happy to help.

These pigments work very well on the glass surface. We have not had enough experience with them to determine that they will work for encasing or mixing with glass.

 

1. Make your bead until it is ready to be placed in the annealer or kiln.

2. Allow the bead to cool just a bit until it no longer glows. If it is still glowing, that much heat will not affect the pigment, but rolling it in the pigment may deform your bead. So be sure your bead is cooled enough to be hard.

3. Roll the hot bead in your pigment that is placed on a metal or graphite surface. Cover the bead area thoroughly, making sure there are no bare spots. The pigment sticks nicely to hot glass.

4. Place the bead back into the flame and reheat the surface. There is no need to reheat the bead so the glass softens and begins to change shape. All you need to do is heat the very surface enough so the pigment adheres to the glass.

5. Place your bead into your preheated annealer or kiln and run it through the annealing process when you are ready. If you'd prefer to cool your bead at this point, you can. Some of the loose pigment will come of onto your blanket though. This won't hurt the bead pigment, but will mess up your blanket. Also, it is always best to anneal after working with pigments for the best success.

6. Once your bead is annealed and cool, wipe the bead off. Some loose pigment will come off, leaving a beautiful glimmer underneath. This glimmer on the glass will be permanent.
