A highly concentrated blue colour liquid candle dye in a 10ml dropper bottle for easy dispensing. Our dyes are oil based and designed to be used in paraffin wax, vegetable wax, soy wax, gel wax. Our liquid dyes are a professional grade and the most soluble colourant available. Use them when you want a candle to be dyed throughout (not over-dipping). They can be easily mixed together to create other colours. They are extremely concentrated. 1-5ml of dye wax will colour approx 1kg of wax. The more drops you use the more intense the colour.
