Old Hickory Wilco-SLU Kaolin Clay (discontinued **)
Categories:	Ceramic; Clay; Kaolin Clay
Material Notes:	Wilco SLU is an aqueous suspension of kaolin produced at 70% solids content. The slurry is deflocculated and rheology stabilized with sodium silicate. The Wilco SLU grade is a highly permeable selection and recognized for its coarse particle size distribution. In a ceramic casting formulation, it offers fast casting rate for reduced casting times and quick firming of the piece upon drainage of the mold and removal of the piece for drying.
