Liquitex makes acrylics in three consistencies: Soft Body, Heavy Body, and Super Heavy Body. All three have the same amount of pigment per ounce of product. But, each is mixed with a different medium which controls how the pigment molecules slide past each other when pushed by a brush or painting knife. Liquitex Super Heavy Body Acrylics are handled best by painting knives to achieve 3D and impasto effects with no shrinkage and up to 2 inch peaks. They are packaged in several jar sizes.
