Can large candles such as a 12″ x 12″ be made?
Yes, an enormous candle such as that can be made. Pour the candle as you would normally. Due to the large size of the candle, you may have to do more than two pours. To find a wick, practice with some smaller candles first (this will save you time, money, and energy in the long run). Once you find a wick that gives you the burn, flame size, and quality you are looking for, measure the diameter of the burn pool for that wick. When you design the wick pattern of the large candle, overlap the burn pool diameters a tad to get an even burn. Be sure to leave about a half-inch wall on the candle as it burns down.
