An inexpensive double boiler setup that prevents the wax from reaching dangerously high temperatures. Also includes a thermometer and stir sticks. Most popular for pillars are Kemamide release powder, Vybar 103, stearic powder (regular or vegetable), and parol oil. For a good scented candle a 5% fragrance usage level is recommended. A 5% usage works out to about 1 ounce per pound of wax. If purchasing one case of wax you may want to consider up to 2 ½ - 3 pounds of scent. There are many things that go into sizing the wick including the wax you select, how much scent is added and even the color.

  Please note that Zinc Core wicks are the easiest to use for container fill candles.
You need to use scents that are non-polar and have a flash point of 170 degrees F when making gel candles. Other fragrances can migrate out of the gel and cause problems.

  Selecting the proper wick is critical with gel candles due to the higher burning temperatures of this product. It is also very important to select the proper sustainer base for the pre-wick assembly. The key element in the sustainer base is the "neck height," which is the part that holds the wick upright. A longer neck helps to ensure that the flame is extinguished before reaching the bottom of the container.
Once the wax has completely melted, we add color wax dye, if color is wanted. We then let the wax dye melt for about 5 minutes.  Stir it until it is completely dissolved and mixed in. 
Some scents, I have found, have their own unique colors and do not need color added. like Gardenia, it comes out a shade of green.
Try to remember that wax is hotter when it has melted, then when it is melting.  Why? Because some of you try to make this "instant wax melt" and this takes time.  If it is smoking, you have the temperature to high. 

  Once again - wax will catch fire if it gets to 390 degrees or there about.  It is like grease and burst into flames on it's on if you have the temp. to high.  Use your common sense.  It is no dangerous then cooking, but you have to have common sense.  Wax takes time to melt.  That is just how it is.
One block of dye will color up to 20 pounds of wax.  It comes out a nice pastel color.  You must use more a deeper color.  But remember, too much will spoil your attempt at making a candle. Don't use a microwave to melt wax.
Never leave wax on a stove without adult supervision.  Wax has a flash point and will catch fire if it gets to hot!  Just like grease!

  If we accidentally spill hot wax on us, we cool with tap cold water.  Brushing it off just spreads the wax and burns more.  This is also why we keep the temperature lower, so we don't get burnt.
Pour scented candles in a well ventilated area, these are chemicals, remember. You wouldn't exhale bleach all day or Lysol, would you?
Do not drink the liquid, nor do we let small children around the scent...it smells like it would taste good! 
Don't let the wax and scent mixture to linger on the heat as this will evaporate the scent!
Only pour wax into containers made to hold hot liquids - never pour hot wax into cold glass containers. 
Never burn a candle in a container not made to stand high temperatures.
Never leave a burning candle alone.
