Slip (ceramics)

A slip is a suspension in water of clay and/or other materials used in the production of ceramic ware.[1] Deflocculant, such as sodium silicate, can be added to the slip to disperse the raw material particles. This allows a higher solids content to be used, or allows a fluid slip to be produced with the a minimum of water so that drying shrinkage is minimised, which is important during slipcasting[2]. Usually the mixing of slip is undertaken in a blunger[3] although it can be done using other types of mixers or even by hand.

An engobe is a material similar to a slip, with somewhat lower clay content, higher proportion of flux, and added filler, and in some cases a colorant.[4]

Use

A slip may be made for various purposes in the production and decoration of ceramics. Slip can be used:
