Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to make decorative candles [title] Pick your wax. [step] Soy, paraffin, and beeswax are the most popular waxes for candle-making. Paraffin wax was traditionally used for candles, but as a petroleum product it may not be the best for the air in your home.

Ending1: Soy wax is easy to find, simple to use, and is a clean vegetable-based wax. [substeps] Beeswax candles can actually purify the air, but the wax must be mixed with another oil to lower the melting point so that you can actually burn the candle. Ending2: Paraffin wax is age-appropriate and does not contain additives like fragrance, resin, oil, or baking soda, which can bind to candle wax. It also can melt on modern candles and ruin candles' flavor. Ending3: Choose the right wax according to your own preferences. [substeps] Tea tree oil is your best bet. Ending4: Wax stands from evaporation, so it can be purchased at most grocery and hobby stores. Soy wax is generally a varnish-like gel which dries quickly, but it thickens a little faster and is easier to apply.
