Candle molds - Polycarbonate moldsAh, plastic! Resistant, inexpensive, available in hundreds of different shapes and sizes, polycarbonate (or plastic) molds will help you in many ways!
One-piece molds are the most common and their shapes include cylinders of all sizes and diameters (like the three molds left on the picture), squares, hexagons, decagons and all sorts of -gons, the list is not exhaustive.
Spherical or other unregulat shapes are obtained with two-pieces molds whose pieces fit together (if they weren't made of two pieces, you'd have a hard time removing the finished candle)
The place where the two halves join, called the seam, needs to be covered with a generous amount of mold sealer before you start pouring the wax. If you don't take this precaution, you'll end up with a candle in the shape of a semi-sphere and a table top covered in paraffin.
When you unmold a candle made in a two-pieces mold, you will notice a seam line at the place where the two parts of the mold come together. To remove this line, use a kitchen knife to scrap most of the excess wax (be sure not to carve into the candle) then "polish" the candle with an old panty hose.
