When shaped bath bombs pop out of the containers easily, they are done. Seal individually in plastic wrap. To use, drop one or two into running bath water. As soon as it is melted, add fragrance and color and pour into jars. Let set for six to eight hours.
Place lids on jars.
Open jars will lightly scent rooms for several weeks. Hand-decorated glassware and plates. Paint designs with perm-enamel paints. Candles are easy to make, and can be a good family project. Dough ornaments will last for years.
