500mL DARVAN 7

Used to minimize the amount of water needed to produce a free-flowing clay slip. Compared to traditional sodium silicate / soda ash deflocculants, more is required to thin slips (about 0.5% of the dry ingredients) but it is easier on plaster molds and is more forgiving if used in excess.
