Reusable mold making material

A composition used for mold making to form a thermoreversible colloidal gel comprising an aqueous solution of a humectant, a protein, and at least one nanofiller.

A flexible mold making composition comprising:

• a matrix including a gelling hydrocolloid system, humectants, firming agent, and a nanofibrous material embedded in said matrix.

A process for making at least two different moldable parts, which comprises forming a first mold for making a first moldable part, said first mold being made from a moldable composition comprising a thermoreversible resin including a gelling hydrocolloid system and humectant, and at least one nanofiller, molding said first moldable part using said first mold, removing said first moldable part from said first mold, heating said first mold to melt said first mold to return said first mold to said moldable composition, forming a second mold for making a second moldable part at least in part from said moldable composition, and molding said second moldable part using said second mold.
