Abstract
A composition with the required chipping characteristics can be formed into a solid block surrounding objects to be exposed by chipping away the material of the block to define a paleontology or similar toy. The composition contains rounded granite particles of two different mesh sizes, a wax filler material in the interstices between the particles and a separate binder to form the structure into a solid block.

A chipable composition for use in a toy for excavating a recoverable object buried in the composition comprising:
- a particulate mineral material having particles sized to a mesh size in the range up to 30 mesh;
- a non-toxic wax filler material in interstices between the particles of the particulate material, the amount of the wax material being greater than zero but less than 4.2 percent of a total weight;
- and a non-toxic binder acting to bind the particulate materials and the filler into a solid block, the binder being used in an amount such that the composition can be manually chipped away from an embedded object to expose the object to be recovered from the composition, the amount of the binder being greater than zero but less than 7 percent of the total weight.
A method of forming a chipable composition for use in a toy for excavating a recoverable object buried in the composition, the method comprising:
- providing a particulate mineral material having particles sized to a mesh size in the range up to 30 mesh;
- providing a non-toxic wax filler material, the amount of the wax material being greater than zero but less than 4.2 percent of a total weight of the composition;
- providing a non-toxic binder, the amount of the binder being greater than zero but less than 7 percent of the total weight;
- the wax filler material being supplied as an emulsion in water;
- intimately mixing the particulate material and the wax filler material emulsion so that the wax filler material enters into interstices between the particles of the particulate material;
- and activating the binder with a catalyst to bind the particulate materials and the wax filler material into a solid block, the binder being used in an amount such that the composition can be manually chipped away from an embedded object to expose the object to be recovered from the composition.
