![811 Cone 6 Porcelain Casting Slip](http://psh.ca/cdn/shop/files/C8113_{width}x.jpg?v=1691675707)
811 Porcelain slip fires off-white and translucent at cone 6. It is highly vitrified so larger forms are more prone to deforming or slumping than other slips. For large forms, firing to cone 5 still produces a vitrified body suitable for functional ware while being more resistant to slumping.
