Promat differs from Sculpey in being firmer in texture - harder to condition, but less prone to smearing, stronger when fired, and flexible in thin sheets. Promat is made by the same company as Sculpey.


There is also a soft formulation of Fimo that comes in a different selection of colors. Fimo has a very beautiful selection of colors, including two transparent clays, six "stone" textured clays, a glow-in-the-dark, and metallics ("perlglantz"). When fired, Fimo has a slightly glossy, "plasticky"-looking surface. Fimo's firmness lets it hold very fine detail in canework smearing is rare. It is the stiffest of the clays and the most difficult to condition. Fimo comes in 58g (about 2 ounces) and 350g (about 12.5 ounces) packages. Premo was developed by the Clay Factory, and earlier versions were known as Clay Factory Clay (CFC).įimo is a widely-available polymer clay and probably the most popular among clay artists, although you may not be able to find all of the colors locally. The colors are drawn from a "painter's palette" of warm and cool blues, yellows, and reds, so those with a background in color theory will find it easier to mix custom colors to their own specifications. This brand is fairly soft and easy to condition, but holds detail in canes well. This replacement for Promat is the newest of the clays. This clay comes in about 30 colors, including translucent, brights, metallics, and fluorescents. The light colors seem to be mixed with white and can be a little dull. The colors are strong and may overwhelm colors in other clays when mixed if you're mixing Sculpey III with another clay brand, start with small amounts of the Sculpey III and watch the color. (You can work around this problem by chilling your Sculpey canes before slicing them.) Sculpey III develops a slightly porous, matte finish after firing, which looks especially good with dark colors, but does not buff to as high a shine as finer-grained clays and is not as strong when fired. Sculpey III is the softest and easiest to condition of the commonly available clays however, it gets softer the more it's worked, and easily smears when used in canes. It comes in about 40 colors in 2-oz packages, and is usually easy to find. Sculpey III is most often used by clay artists.It's stronger and more flexible when fired than original Sculpey, sometimes used for doll-making. Super Sculpey comes only in flesh-tone in 1-lb boxes.It is a soft clay, very brittle and chalky when fired, and is the least expensive of the clays. The original Sculpey comes only in white, in 2-lb boxes.Some of the available brands are: Sculpey Polyform Products Co. There's no one answer to this question each clay brand has its own strengths and weaknesses, and different clay artists have different preferences.
