My invention relates to the art of making three dimensional impressions and likenesses. More specifically, my invention is an improvement of making three dimensional duplicate of a persons facial appearance and expression. The steps of my method include the formation of a mold by applying a base impression material such as irreversible hydrocolloid to the face of the model; base material being applied in a semi-liquid state and hardening to a gel-like consistency in a short period of time; applying fibrous bonding patches in the liquified base material shortly after the base material is placed on the model and prior to setup; applying plaster of paris strips to the base material, the plaster of paris strips connecting to the mold created by the base material by the fibrous bonding patches which have embedded themselves in the base material and which will likewise embedd themselves in the plaster of paris; allowing the plaster of paris strips to harden; removing the mold from the model's face; and finally filling the mold with a material such as gypsum stone, which is poured into the mold in a liquified form and which will harden in a short period of time to form a permanent duplicate of the model's face and expression.
