Super Sculpey FIRM Grey Polymer Clay, 1 x 1lb block


Super Sculpey Firm Grey Polymer Modelling Clay is great news for Sculptors. The firmness of this product enables fine detailed modelling with good shadows - unlike Super Sculpey translucent.

Sculpey SAYS: Many Sculptors desire an extra firm clay that can be "carved" and used for projects that require fine details. Super Sculpey FIRM is the extra firm sculpting clay that is grey in color, allowing sculptors to create fine details and photographers to catch these fine points on film. Unique in both form and color, this sculpting clay brings creative options to the sculpting world.

This ceramic like sculpturing compound oven bakes to a shatter and chip resistant finish.

Used by movie animation studios and professionals worldwide for prototypes, maquettes, and all kinds of dolls. Super Sculpey has a long track record as a superb clay for sculpting. The finest detail is achievable and added clay can be smoothed in seamlessly.


Super Sculpey Firm Grey is designed to NOT be an easy to condition polymer clay as it is designed for insitu sculpting. It should be carved and features fine tooling and detailing characteristics, and does not "fill in" after tooling. If you opt to paint your cured piece, we recommend acrylic paint or the application of water based glaze prior to painting with oils. Paint should be applied in thin washes rather than thick coats for the best paint to clay bond. After curing, Super Sculpey bakes to a ceramic-like hardness and can be sanded to a fine smoothness.


Super Sculpey should be cured in a preheated 275 degree F (130 degree C) oven for 15 minutes per quarter inch of thickness. DO NOT MICROWAVE. For example, a piece of ½" thickness would be cured for 30 minutes. The layering method is recommended for larger pieces of construction.


Because of the fine tooling and detailing characteristics of Super Sculpey, it is frequently the chosen clay for making prototypes from which moulds are made from the Super Sculpey sculptures; then reproductions are made using the molds. Additionally, artists are producing finely detailed finished sculptures using Super Sculpey.


Sculpey polymer clay products should remain fresh if properly stored in a cool place, away from heat and direct sunlight.
