Abstract
Modeling compounds and methods for making the same are described. The modeling compounds, in some embodiments, comprise about 20% to about 40% by weight starch-based binder, and about 0.15% to about 1.2% by weight microspheres dispersed throughout the compounds. In some embodiments, the modeling compound further comprises vinylpyrrolidone polymers.
