Glow Glass


Impregnating glass with glow in the dark pigment will create an effect similar to having a light under a glass figurine.  All of our powders are compatible with raw molten glass.  The only issue is temperature which varies between products.  Basically, if the pigment melts, then it is destroyed. Therefore, check the melting point on the MSDS before heating any of our glow in the dark pigments.

Glow in the dark pigments with daytime fluorescent pigments melt around 143F and would not be appropriate for heated glass       manufacturing.

On the other hand, most of our products can be heated to 2500 F before they begin to break down.


The above picture is a bit of a cheat.  It is actually a store-purchased 6" glass orb with negative-space elongated bubbles inside.  For the photo, it was sat atop a layer of Ultra Green Glow in the Dark Sand.  This lighting effect works great with ornamental glass and crystal.  It takes about 10 seconds to prepare and can be done with our paint or powder products.


The following additional information was graciously donated by glassworker Alex Ubatuba:

There cannot be any sulfur, uranium doped, or large amounts of Zinc mixed in with any of the glow colors.  I have had previous "experimental" colors that cause a chemical reaction to the glass. In particularly the red and orange colors, and in one rare case a violet color are prone to such problems such as: Out of control bubbling, or black sooty smoke, or a strong sulfur odor were produced. Silicate base can aid with the color actually melting into the surface. Otherwise if the pigment can take the heat involved with glass working, it can be mixed in with raw clear glass powder.  Large clumps of pigment can cause the piece to crack during cooling.  Very fine pigment the consistency of bakers sugar works the best.

[Engineers note:  Ultra Green, Ultra Blue, and Pure Blue would probably be the best fit.]

Alex is currently doing some experiments and sculpture with our pigments.  We will update this page with technical information and photos as he proceeds.  We are always looking for glow in the dark art to showcase.  If you are an artist and would like us to display your work, please send us an email.
