The ancient technique of hand-dipping candles -- repeatedly dipping a weighted wick in melted wax -- remains unchanged today. Two candles are dipped at once, one at each end of a long wick.
Heated wax can ignite, so never leave it unattended; lower heat immediately if wax begins to burn or smoke. The color can be deepened or altered with shavings of darker beeswax or wax-dye pellets. Use 15-ply wicking for thin tapers, 24-ply for candles thicker than 1/2 inch.
