Heat the second 1/3 of the wax to 180 degrees and add the fragrance and color. For the middle layer, I used 4 drops of blue liquid candle dye. Let the wax cool to 10 degrees hotter than you poured the first layer. (eg. If you poured at 130 degrees, your second pour will be at 140 degrees.)
Give the jars a quick zap with the heat gun - concentrating more on the outside of the jar than the inside. You want to warm them back up a bit, but you don't want to melt the top of the first layer.
Slowly pour the second layer onto the first, again, being careful not to spill wax down the inside of the jar.
Again, let them cool for 45-60 minutes. Repeat the step, again heating your wax to 180 degrees, adding the fragrance and color (I used 2 drops for this layer.) and pouring the layer at 10 degrees hotter than you poured the previous layer.
