ES40 Handbuilding White has an appearance and firing range similar to ES5 Earthstone Original White. The addition of coarse molochite makes ES40 Earthstone Handbuilding an incredibly strong clay. It is heavily enough grogged to make the most extreme sculptural forms and is highly resistant to warping and cracking. ES40 is an ideal clay body for making hand made tiles and ceramic murals.

• Incredibly strong clay
• Heavily grogged
• Excellent for sculptural forms, handmade tiles and murals
