FC-120
The FC-120 clay is a special selection for sanitaryware. It is very fast casting and is designed to use in combination with the C-33A or other finer particle size distribution clay. The FC-120 provides excellent casting rate in a sanitaryware formula while maintaining a long plasticity range for trimming and finishing operations. The unique mineralogy of FC-120 also provides god dry strength by comparison to the fast casting rate.
