Spirits of Soap is a surfactant comprised of a proprietary blend of soap and alcohol. Spirits of Soap is often misted with a mouth atomizer or sprinkled with a whisk over your pattern to break the colors up into spider veins. Do not mix with your colors! Sold in 2oz bottles or by the pint.  

Safety note: if using with a mouth atomizer, please take care not to inhale the misted vapor.
