The glow in the dark powder is an opaque pigment that does not actually dissolve in candle gel, but rather is suspended. Mixing glow powder with candle gel (we recommend penreco MD or HD) creates a white opaque looking material. You cannot see through it. One method that we have used for this material is to pour a bottom layer of a powder/gel mix with a clear gel over pour. We have had the most success with a bottom layer, which is about 1/5 to 1/8, the depth of the candle.
The glow in the dark powder/gel mixture then provides bottom light, which glows through the clear gel. A very clear gel does not pick up the light. Objects or bubbles suspended in the gel reflect the light emitted by the Glow Powder and will be seen as suspended in midair. (So make lots of bubbles when you pour clear over it!) The way the Glow Powder is used is up to the artist's imagination! You can also make the entire candle with the glow powder/gel mix! It is all up to you!
A starting point is to make a 5% stock. 5 parts of Glow Powder mixed with 95 parts of melted gel. This is not a critical mix. Variations of this mix can be used depending on the effects you want to achieve. Get the temperature of the gel in the 200-210 F range. Fragrance Gel is done at much lower temperatures (140 F). Add the powder and mix well, Make sure that all the material is dispersed well in the solution and none remains on the bottom. Always mix well just before you pour. This stock solution can be reheated. Try to keep the same container for your stock solution and reheat and add your new material to it.
Pour your gel/luminous powder mix into a pan. Let cool, & using cookie cutters cut out pieces, or pour gel into moulds. Stick the "glowing" gel pieces to the sides of candle dish, then pour clear gel over. They will appear suspended within gel!!
Make or purchase a paraffin candle. Melt candle wax, and following usage amounts, add glow powder. Make sure you mix well before dipping candles, because powder will settle. Dip your candle in 2 or 3 times, drying between each dip. You only need to do this for the last layers of wax to save on cost.
