Start by measuring all of your ingredients. If you're using a bar weigh 115 grams of beeswax.
Put 3 inches of water in a pot and bring it to a low simmer. Cover the simmering water with the glass bowl. Make sure the bowl doesn't sit in the water.
Combine all of the ingredients in the bowl, and slowly stir. Continue to stir the ingredients until they are all melted and combined.
Remove the melted ingredients from the stove and carefully pour the liquid into the molds.
Allow the bars to cool at room temperature until they are firm.
