LC Light clay plastic smooth to 35–40% touch; slight resistance to shearing between thumb and forefinger; will form ribbon of 50–75 mm. LMC Light medium clay plastic bolus; smooth to 40–45% touch; slight to moderate resistance to ribboning shear; will form ribbon of about 75 mm. MC Medium clay smooth plastic bolus; 45–55% handles like plasticine and can be moulded into rods without fracture; has moderate resistance to ribboning shear; will form ribbon of 75 mm or more. MHC Medium clay smooth plastic bolus; 50% or more handles like plasticine; can be moulded into rods without fracture; has moderate to firm resistance to ribboning shear; will form ribbon of 75 mm or more. HC Heavy clay smooth plastic bolus; 50% or more handles like stiff plasticine; can be moulded into rods without fracture; has firm resistance to ribboning shear; will form ribbon of 75 mm or more.
