Candle Making: Additives

Other additives you might consider in candle making will aid in the setting and desired rigidity.

Stearic Acid

Stearic acid, or stearine, is an animal fat byproduct, but you can find a vegetable (palm oil based) substitute available. It acts as a hardener for low melt point waxes, and lowers the melt point of higher temperature waxes. Take care not to use too much as over-use will have mottled candles as a consequence. The recommended amount for making candles is 3 tsp. per lb of wax and it can be used in any amount from 1% to 100%.

Vybar

Vybar is used to make the wax hard, impart a creamy texture and assist in the scent throw of the candle. There are two types of vybar: - vybar 103 which is used for wax with a melt point of 131 or higher, and vybar 260 which is used for wax with a melt point of 130 and lower. Vybar will also reduce mottling and tiny air bubbles. Take care not us use too much Vybar as over-use can result in binding the candle scent, resulting in a poor or non existent scent throw. The recommended amount to use when making candles is between ½ tsp. to 1 tsp. per pound of wax.

Luster crystals

Luster crystals are absolutely fantastic when making white candles. It is a man-made wax polymer. Using luster crystal will result in your candles having brighter colors, your candle will burn longer, and the wax will be opaque.

Clear Crystals

Yet another polymer that acts like luster crystals are the clear crystals. It will harden the candle wax like luster crystals but makes the wax more transparent for a glowing effect whereas luster crystals will the candle opaque in the end.

Plastic additives

Plastic additives are used when making hurricane and embedded candles. Plastic additives will also harden the wax like the other additives with a major difference: the high melting point also makes it perfect in the making of these candles. Plastic additives also result in a transparent effect on homemade candles. Special care must be taken when using this product as plastic additives require heating over a direct heat source before adding to the correct temperature wax.

Microcrystaline Wax or Micro Wax

Microcrystaline wax, or micro wax as it is also known, comes in many different grades – all for different uses. One grade can be used as a hardener and another grade can be added to container candles to soften the wax and help reduce wet spots. Microcrystaline soft is also used for hand molding candles.

UV inhibitor

If you know that the candles that you will be making will have to stand displayed in a sunny window sill or even outdoors for a craft market, then it is advisable to add UV inhibitor to your candles. Purple and red candles have a reputation for fading the quickest under UV light. UV inhibitor will only help to protect the candle; it cannot guarantee that they will not fade eventually. The recommended use 1/8 tsp. to 1 lb wax.

Mineral Oil

If you want your candles to have a mottled look, especially if it is part of your artistic impression, you could add approximately 2 to 3 tsp. mineral oil to 1 lb candle wax to achieve the mottled look.
