There are several things you can try to lessen the effect of frosting:

• Try mixing your melted wax less vigorously.
• Preheat glassware in a warm oven to a maximum of 100 degrees.
• Pour your wax at a lower temperature to help reduce the crystal formation.
• Adding color makes frosting more noticeable, so making non-colored soy candles will make it less noticeable.
• Add 1/2% (or 1/8 tsp. per pound) UV Inhibitor to help protect the wax from the frosting effects light has on it.
• Cool at room temperature and keep out of drafts.
• Elevate the candles on a wire cooling rack so the counter or table top doesn't pull the heat out the bottom of the container and cause the wax to cool too fast.
• Try a wax that tries to reduce frosting, such as the CB Advanced soy.
