Bekro Candle Dye - 10g Bag. We recommend using Bekro dye at 0.4%, so this 10g bag will colour approximately 5kg of paraffin wax. Soy and other vegetable waxes may require additional loading to achieve deep colour. The image shows an approximation of the dye colours when used in paraffin wax. Actual colours will vary with the wax and additives used. Experimentation is encouraged.
