There are many options when it comes to choosing a brand of clay, and each brand has different properties and benefits. I keep a few different brands in my own stash. Hopefully this list can help you decide which brand is right for your project:
Sculpey III: This clay has a wide variety of beautiful colors, and is low in cost. Though it is also considered more brittle/fragile than other brands, it is a great choice for beginners.
Premo! Sculpey: This brand is strong and flexible when cured, and the colors are brilliant. This is the preferred brand of many clay artists.
Super Sculpey: This clay is a pinkish-beige sort of color that is somewhat prone to “plaquing.” The addition of a stronger more opaque clay can eliminate most problems.
FIMO Classic/Soft: Soft is easier to condition than Classic, but both types will hold the finer details of cane work. Great colors available that come in blocks of 8 segments allowing for easier cutting and blending.
Cernit: The German clay is one of the strongest on the market, and has a wide range of flesh tones. It is soft and sticky when warm, so it is better suited for doll-making than cane work.
Kato polyclay: Being one of the newer brands on the market, this clay is both strong and flexible. It can be difficult to sand, and it has a strong vinyl odor.
Liquid Sculpey: This product has many different uses including smoothing surfaces, attaching two pieces, and creating faux materials. The translucent brand can be tinted to any color desired.
Tomorrow I will post my tutorial for making polymer clay Rorschach Focal Beads using Sculpey III!
