How to Make Glow In The Dark Candles
Glow in the dark candles emit a
soft glow even when not lit. This
makes them ideal to use as
night-lights. If you make them
without a wick, they make a great
gift for hospital patients where a
normal candle would not be
This article will cover some technical aspects of making glow in the
dark candles for those who enjoy making candles at home.
There are several methods to adding glow materials to candles:
The intuitive method is to thoroughly mix the glow material directly
into the wax or gel. The benefit is that you can achieve a very
consistent glow. Unfortunately, there are two issues with this method.
When you mix glow powder into gel or other clear mediums, it will cause
it to have a cloudy appearance. If you mix it into a more opaque medium,
like dyed wax, then only the glow material on the outside layer will
charge and glow. Therefore, some glow material is wasted and the candle
does not glow as bright as it could.
For clear gel and other clear mediums, you should consider putting a
thin layer of pure glow material only on the bottom of the candle. The
glow from this layer then projects up through the gel and reflects off
of the glass and gel surfaces. The result is an interesting and stunning
effect that surpasses simply making the candle glow in the dark.
For more opaque mediums, like wax, the best result can be obtained by
putting a layer of glow material only on the outer surfaces. The method
varies depending on if you are molding your candle or pouring it into a
For poured glass candles, you will need wax, glass, hairspray, and
some glow in the dark powder. Liberally spray the inside of the glass
with the stickiest hairspray you can find. If you are making more than a
few candles, you may consider substituting spray glue instead of
hairspray. Now that the inside of your glass is sticky, pour in the glow
in the dark powder. Turn and roll the glass until a nice layer of powder
completely coats the inside. Add wax as you would for a regular candle.
For molded candles, coat the inside of your mold with a very thin
layer of liquid vegetable oil or mold release spray. Note, if you have
drips, then you are using way too much. Pour in your glow in the dark
powder. Turn and roll the mold until a nice layer of powder completely
coats the inside. Add the wax and follow standard candle making
All glow in the dark materials work by absorbing and holding light.
It releases this light slowly in the form of a glow. While glow in the
dark materials come in a variety of colors, Ultra Green and Ultra Blue
are the brightest colors and therefore make the best candles.
Glow materials come in 3 different forms that are popular for candle
making. When putting a layer on the bottom of a candle, or mixing it
directly into the wax or gel, Glow in the Dark Sand performs best. It is
a granular material that gives a textured glow appearance. It is also
the brightest of the products and is cheaper to buy than the Glow in the
Glow in the Dark Powder is similar to the sand, but the particles are
much smaller. It is the best product for dusting the inside of a mold or
It takes approximately 1/2 Ounce of Glow in the Dark Sand or Powder
to make a medium sized candle using the above methods.
Finally, Glow in the Dark Rocks can create an interesting effect. You
can fill a mold or glass with the rocks and pour hot gel or wax to fill
in the voids. The rocks are not as bright as the upper two products.
Therefore, they do not work well in the bottom layer method.
Transitioning is an advanced glow effect where an object will slowly
change colors as the glow wears off. The different glow colors each have
their own brightness. For example, Ultra Green is 8 times the brightness
of Pure Blue or Zinc Red. It also follows, that a bright product like
Ultra Green glows longer than dimmer products like Pure Blue or Zinc
Red. So the trick is to use enough of the lower powered product to
overcome the brightness of the brighter product in the first minute. As
the lower powered product fades out, the brighter product will overcome.
Although this sounds confusing, it is simple to accomplish. When
making a candle that you want to transition from Zinc Red to Ultra
Green, Mix .5 Oz of Red with .05 Oz of Green and follow any of the
procedures above. You can use the brightness ratings of each product to
determine the ratios.
