The candle, packaging, thermostat and distillation industries are all major users of wax.

Paraffin wax was first produced commercially in 1867, less than 10 years after the first petroleum well was drilled. Paraffin wax precipitates readily from petroleum on chilling.  

Add scent to your melted wax. The scent you choose is up to you. Scents such as essential oils can be purchased at your local craft store. It is best to read the bottles directions rather than base the amount you put in on how strongly it smells after the scent has already been added. Stir well.

Add coloring. Normal food coloring will not work in candles because they are water-based. Purchase oil-based dyes at your local craft store. You can generally find specific candle dyes.

Read the bottle for the proper amount of dye to put in to achieve a certain color. Add drops of coloring until you have reached your desired color. Stir well.
