FROSTING IN SOY CANDLES

FrostedSoyCandle

What is FROSTING?

"Frosting" is a candle making term used to describe the white crystalline layer that forms on the surface of all-natural plant waxes [such as palm and soy container].

imagesWhen making a palm container candle the candlemaker will often use techniques to specifically encourage the formation of the crystalline layer as it creates a spectacular pattern, but in a soy candle, it is often seen as a defect, which it is not.

Some candle lovers [especially those that want an all-natural product] like to see frosting as it visually confirms the wax type. Others see frosting as a defect, mostly because they feel it reduces the visual appeal of the candle.

Interestingly, frosting only occurs when an all-natural plant wax is used. If an additive or another non-vegetable wax is added to the all-natural wax, the molecular structure of the wax is changed and the wax will not frost. 

If you do not like frosting, and wax type is not a priority, there are many soy container wax blends that can be purchased.  Alternatively, many candlemakers prefer not to colour their candles as the frosting becomes far less noticeable, or they select decorative non-see-through candle containers.

How to REDUCE Frosting on Soy Candles

Soy Wax Frosting FAQ

There are a number of techniques, which will assist in eliminating frosting, some work better than others depending on the climate of where you live.

  • Preheat candle containers just prior to pouring. Place the wicked candle containers into a pre-warmed oven [not more than 100 degrees Celsius and for not more than 1-2 minutes].

Please Note: If the oven temperature is higher or you leave the candle containers in for longer, the wax coating on the candlewick will melt, reducing the overall effectiveness of the burn.

  • Pour at a lower temperature -- I always recommend a pour temperature of between 65 and 70 degrees Celsius. I find this reduces frosting and gives me a creamy smooth top, however, start with supplier recommendations.

Please Note: Many all-natural waxes are made in the USA, and instructions for pouring temperatures are based on their climate/humidity. Research is always needed to get it right for your own climate/humidity. If the supplier recommendation is not delivering the results you want, try reducing by 5 degrees, then another 5 degrees till you see improvement.

  • The easiest way to muck up an all-natural soy wax candle is to subject it to temperature fluctuations - they HATE changes to temperature!
  • Pouring candles at the correct temperature is important, but often the importance of the temperature the candle cools and set at is overlooked. 

If the room temperature drops more than 8 degrees [warm to cold] you will end up with frosting, and more than likely, wet spots. Sadly, this happens a lot in Australia, particularly in the cooler months and in the colder states.

There are several ways to remedy changing temperatures:

  • Keep the room your candles are setting and cooling in, at a constant temperature for at least 24 hours, suggest 18-24 degrees Celsius. 
  • If this is not possible, I highly recommend placing a cardboard box or similar type container over the candles and then a blanket to retain the warmth, this will slow down the cooling process and reduce chances of frosting.
  • When we operated Chandelle Galerie, we purchased several non-working fridges. David drilled a hole in the back of the fridges and added reptile wiring. We were then able to set a constant 21-degree temperature for the cooling and setting of all our candles. The beauty of the fridges meant we could hold at least 100-200 candles per fridge at any given time [number relates to candle container size].

I should end this blog by saying, its really important you educate your clients so they understand that frosting is naturally occurring in all-natural candle wax products. 

It is not a FLAW, it's not a DEFECT, and it's not a candlemakers INEXPERIENCE!
