Lac Extract - is a red dye extract from the scale insect Laccifer lacca which is found throughout India, South East Asia, Nepal, Burma, Bhutan and South China. It is found both in the wild and is cultivated. The female lac insects invade host trees (mainly fig and acacia) and the insect secretes a resin that contains the red dye. This is known as stick lac. The resin is also used to make shellac. The dye must be extracted from the resin before it can be used to colour cloth. Lac extract yields crimson to burgundy reds to deep purples. The colourant is similar to cochineal but colours achieved are warmer, softer, and more muted. The lac dye has high light and washfastness on silk and wool. 15-20% dye to wof is all that is needed for a medium depth of shade.    All measures in dyeing are based on the weight of material to be dyed. This is known as the Weight Of Fibre (WOF). WOF gives a convenient way to state how much dyestuff is needed for a given shade, regardless of whether the dyer wants to colour a few yarns or several metres of fabric. The weight of dyestuff is expressed asa percentage of WOF.    For example, to dye a medium-red with madder, we would use 50% WOF. Hence, if we had a pound of cotton (450 g) we would need a half-pound (225 g) of madder.^
