Tips on Special Effects for Candles

Fractures:

Interesting effects can be created with thin line fractures running in many directions.  This can be done by dipping the candle mold into cool or cold water while the candle is still warm, or by putting the warm candle into the refrigerator or freezer for short periods.  Generally, waxes with a high melting point will fracture more easily since they are harder.  However, some waxes with a low melting point may also fracture.  The type of candle wax that creates smaller voids or has a smaller amount of shrinking during the candle cooling period will generally be considered a harder type of wax and will fracture easier.  If you cannot fracture a candle with the wax you have available, try adding a small amount of Luster Crystals; this may give you the desired effect since this type of additive makes a candle more brittle.

Blisters:

Small flecks created by agitation emphasize the candle color, for they show up as white spots.  Flecks or smaller imperfections inside candles can be made by vigorously stirring the wax with a long rod, just before or after pouring the wax into the candle mold.  The problem with stirring the wax before pouring it into the mold is that it agitates any foreign particles that may be poured into the mold and settle there, the settled particles can show on the top of the finished candle.  Agitation with the rod in the mold is difficult, but preferable.  Be careful to not damage the side of the mold.

Mottling:

Mottling in a candle will change some depth of shade in colors, but can also produce interesting effects.  These mottling imperfections can be obtained by adding clear oils, like mineral oil, in amounts of 1 % - 3 % to the melted wax.  When oil is added to the candle wax, some candle coloring may become more brilliant or even darker.  Certain wax dyes will reduce mottling by producing smaller crystals than those found in a regular clear candle.  The mottling effect can be heightened by increasing the setting time of the candle, do this by increasing the temperature of the water bath.  Candle scent will also add to the mottling effect.
