Is Potassium Chloride safe to burn?

[Martrex]

I make my own candles and while having different coloured wax is fun I was wondering if I could make a candle burn with a coloured flame.

I am looking at using Potassium Chloride to create a purple flame and decided to ask someone here if it is safe to add to wax and burn (I have googled the subject fairly thoroughly but I keep getting contradictory answers).

Also; is it likely to cause problems when adding to the wax? After the wax is melted it is usually poured into a mould while at around 70 degrees Celsius.

Any help/advice is appreciated.

Combustion of potassium chloride will yield potassium chlorite. The product is not at all harmful. However, when potassium chloride, a crystalline solid, is added to wax, the combustibility and therefore the ability to give the desired purple color may not be hindered. The best way to learn more about it is to give it a try even on just a small sample of candle/wax.
