Candle Making with Plastic molds


A female bust candle made from a two-piece plastic moldPlastic molds can be messy! Cover the work area with aluminum foil or wax paper, or place the prepared mold and stand in a (a kids shoebox is a good size). foil lined container For added safety, keep the pour area separate from the wax melting area and give yourself plenty of elbow room.

Since wax cannot be poured over 200F into plastic molds, a thermometer is absolutely necessary. Use a double boiler to keep wax at the necessary temperature. Keep a pitcher of water handy to refill boiler as the water evaporates.

The best wax blend I have found to make a solid, opaque candle from a two piece mold is

to 1tsp of lustre crystals and - tsp of vybar to one pound of wax
(melting point 145F).

Pour SLOWLY! Gently rock mold to release large air bubbles after pouring. Slowly stir wax inside the mold with a clean skewer to release small air bubbles.

A water bath is really not necessary. As long as you pourbetween 185-200F and your mixture is completely dissolved you should get a good finish. Remember, removing your melted wax from heat too early may cool your wax below the desired pouring temperature. Always check the temperature of your wax before you pour.

Refill the wax well as it cools. When the candle is finished, smooth out the bottom and trim the seamlines with an exacto at a 45 angle. Buff the surface if needed with a nylon stocking.

The right skull in the picture was sprayed with a candle glaze for an extra shiny appearance.

The left skull was made by filling the plastic mold with recycled wax before pouring.

Remember, making candles well takes practice! Good Luck! If you have any other questions about plastic mold making that cannot be answered below in the Troubleshooting section, or any other type of candlemaking question, feel free to contact us


white flaky finish on candle surface
Wax was poured at too cool a temperature. Wax can cool rapidly when removed from heat. Leave the thermometer in the melting pot until right before you pour and make sure you are pouring between 180 and 200F.
snowy appearance(interior flaking)
Additives were not completely dissolved. It might be necessary to heat plastic additives separately on direct heat(be very careful!). A good method is to melt additives first in the melting pot and then add wax. Remember to stir well so additives will blend completely with your wax.
bubbles in the wax
Wax was poured too quickly or stirred too vigorously. If you already poured too fast, slowly stir the wax inside the mold with a large knitting needle or wooden skewer to release as much air bubbles as you can and let the mold cool slowly.
candle cannot be easily removed from the mold
Wax was poured too hot. You may have damaged the mold. If candle cannot be removed be gentle prying, place mold in the refrigerator for no more than an hour. The candle surface may be marred, and if the inside of the mold was damaged, subsequent candles will have the same surface marks.
