Darvan is a liquid deflocculant that is often preferred for use with plaster molds because, unlike some other deflocculants, Darvan does not degrade the plaster. There are different varieties of Darvan. Darvan 811 is a deflocculant that is similar to Darvan 7, but is more powerful. It takes only a small percentage to deflocculate slip.

A casting slip is a delicate balance of water, powder dynamics, deflocculant, temperature and mix energy (as any of these vary so do the properties of the slurry). Once you have used a slip that has been properly formulated, mixed to the right specific gravity and deflocculated for casting you will never go back to using an inadequate one!
