Cross-linked gel modeling composition
First Claim
1. A cross-linked gel modeling composition which is cohesively strong yet ductile and pliable comprising water, a buffer system to control the pH range for hydration and cross-linking polygalactomannan, a cross-linking agent for polygalactomannan and wood flour, wherein the polygalactomannan and cross-linking agent are present in the amount ranging from about 1% to about 10% and wood flour is present in the amount ranging from about 5% to about 25%, and water is present in a major amount, said percentages being based on the total weight of the composition.

- 9. A process for making a cohesively strong yet ductile and pliable modeling composition comprising the steps of mixing a buffer component on the acid side, water, wood flour, guar gum, and a cross-linking agent for the guar gum of the boron oxide type until complete hydration of the guar gum occurs, and then combining with additional water which is premixed with a buffer component on the basic side until cross-linking of the guar gum occurs.
