High-quality soluble pigment dye for candle wax, in red, from the German company Bekro, is added to melted wax at a ratio of approximately 2 g per 1 kg of wax. This dye is used to colour the whole product, although the fragrance concentration in the candle can also affect the pigment's colouring power. We therefore recommend testing the final colour on a small sample before making the whole product.Technical data sheet available for download here.
