Monu-Melt brings all of the qualities of Clayette – a sulfur-free, non- hardening, tack-free, odor-free, and flexible clay – into a formula that can be melted and applied by brush. By popular demand this material has been introduced in a Dark Forest Green color. Monu-Melt will not oxidize and can be left out or heated and cooled repeatedly without any significant change. Will not dry or crack. Monu-Melt should be melted in a range from 180-200°F. Keeping the clay above 200°F will result in bubbling of the liquid clay. This bubbling is mostly aesthetic, and will not affect the characteristics of the cool clay. Hard hardness, green/gray color.
