Wet Screening

The clay slurry (also called slip) is then double screened into a large holding tank. (This tank holds 5 batches of slurry.) Large contamination, rocks, roots, etc., are removed using the first screen, the slip is then passed through a fine 60-mesh screen, which removes any remaining pebbles or undissolved clay leaving a smooth, creamy liquid. Wet blunging and screening allow Blackjack to remove contamination from the clay material. The same contamination that Blackjack screens off, is ground and bagged with the ground clay bought in the standard 50 pound dried clay bags. This dried clay is then used to make clay bodies and sold by ceramic suppliers to potters.

The wet blunging and screening is the defining difference between a clay "processor" and a clay producer. This processing is a difference you can
feel!
