ABSTRACT:
Method of making a sculptured plastic encasement with curved transparent optical quality front and rear faces formed by separately casting each face, then encasing an object within one of the face castings. Afterward on each casting a flat open to the air surface is formed and thereafter the flat surfaces are laminated together. The unitary casting is then trimmed to size, in a way which leaves roughened edge surfaces that can hold a tint.
The encasement is made from room temperature curing transparent resin, and the object encased may be a scene sculpted from fragile materials like grass, seeds, etc.
