Besides this is my first instructable, so feel free to give advice for my next one!
Step 1: Materials & Tools
- candle wax, or old candles you have lying around
- 2 cooking pots/pans for melting the wax
- candle wicks, or similar strings or cords (no plastic stuff)
For making the molds:
You can use a large variety of materials for the molds, but there are some things to remember when choosing a specific material. I will describe some that I have used.
- foamboard (foam inbetween 2 layers of thin smooth cardboard), is sturdy enough not to deform when you pour the wax. makes for smooth surfaces.
- thin cardboard, can be both smooth or rough, texture will reflect on the candle surface.
IMPORTANT! thin cardboard can bend inwards while the wax is cooling (and shrinking)!
- a hobby knife to cut the materials
- glue, hobby glue or any woodglue will do
- masking tape to hold the mold in place while the glue dries
Step 2: Designing Your Candles & Molds
Pouring from the top or bottom of the candle is the easiest way to insert the wick, because it can simply hang in the wax. If your design requires you to pour from the side (see image) you need to think about how to insert the wick and keep it steady while the wax dries!
In my examples I used 1-time molds, that can't be re-used. If you use a more solid material, such as wood, MDF, or plexiglass, you can probably shake the candle out of it without ruining the mold.
Step 3: Building the Mold
- make sure the mold is sturdy enough to withstand the pressure from the wax (in case you want to make a large candle with a thin cardboard mold)
- make sure to glue the entire length of the mold's edge to prevent any leaks
- insert the wick and make sure it's hanging/standing straight and vertical
Step 4: Melting the Wax
IMPORTANT! Never leave the wax unattended while melting! Always use a double-boiler or 2 pots to melt the wax. Set the fire to low and wait for the wax to melt.
If necessary, pull out the wicks with a stick or some old scissors.
You can turn off the fire when the wax is almost completely melted. The final pieces will melt in the hot wax.
Step 5: Pouring the Wax
If you make 2-colored candles, mark the cardboard halfway.
In my design, I put in the wick after the first layer (color) had cooled. To make sure the wick stayed in shape, I put it in the molten wax and shaped it on my design while it cooled.
When pouring mutiple layers of wax, make sure the previous one has cooled completely.
Step 6: Let the Wax Harden
The wax should be hard after a couple of hours, but put it in overnight to be sure before you remove the mold.
Step 7: Remove the Mold
Try to move the cardboard or foam, to see if it will come loose by itself. Then slowly break it off.
NOTE! I will never again make a candle with holes as small as the one below. The cardboard was extremely difficult to get out of the candle. Maybe if you use smoother material or something sturdy you can yank out it will work out better...
Step 8: Enjoy Your Custom Candles!
I hope this instructable helps to inspire people to make their own design candles, and I would like to see the results if you make some!
