Gel wax is a transparent, rubbery compound composed of mineral oil and polymer resin; capable of burning almost twice as long as paraffin wax candles. The approximate percentage of these two elements is 95% mineral oil and 5% polymer resin. The mineral oil is too loose in its original form, and that is where the polymer resin comes into play. This resin is used to thicken the mineral oil to give it the clear, slow burning wax that we know it as. Gel wax is only to be used as a container wax. The gel itself is not sturdy enough to stand alone like pillar wax is. If you are planning to embed your Gel Wax candles, choose non-flammable items such as sea glass, sand, glitter, sea shells, marbles, glass figurines, wax embeds. Never use plastic embeds in your gel wax candles. Decorating your gel wax candles with these embeds can produce beautiful artwork, but remember to leave enough room for the gel wax Gel Wax is mainly composed of oil, you have to make sure that the fragrance oils that you are using are soluble in it. In order to find the wick you are looking for, you must measure the diameter of the opening on your candle container. Once you have this information, you need to select the appropriate Zinc Wick. Do not be tempted to purchase a cotton wick. These wicks have a tendency to absorb too much gel and this will extinguish them. From this point, it is just finding the right wick according to your diameter and then selecting the next bigger sized wick.
