Abstract
Abstract A process of inlaying a design in molded simulated marble or the like comprising the steps of applying a release coating to the inner bottom surface of a mold, applying a transparent gel coat on said release coating, smoothing a piece of porous flexible sheet material bearing the design on one face thereof on the gel coat in the mold to conform to the surface of the gel coat with the one face of the piece of cloth bearing the design toward the gel coat, and casting a hardenable marble mix in the mold over the piece of cloth. The marble mix is then allowed to harden for removal of the resultant simulated marble slab from the mold, the piece of sheet material being embedded in the slab with the design viewable through the transparent gel coat.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
152 words
A process of inlaying a design in molded synthetic marble comprising: applying a release coating to the inner bottom surface of a mold; applying a transparent gel coat on said release coating; placing a piece of porous flexible sheet material bearing said design on one face thereof on the gel coat in the mold, with said one face toward the gel coat; smoothing said piece of sheet material on said gel coat to contour it to the surface of the gel coat and to remove any air trapped beneath it, with any such air escaping up through the porous sheet material; casting a hardenable marble mix in the mold over the piece of sheet material; and allowing the marble mix to harden for removal of the resultant synthetic marble slab from the mold, said piece of sheet material being inlaid in the slab with the design viewable through said transparent gel coat.
Claim 2
Dependent Claim
152 words
A process of inlaying a design in molded synthetic marble comprising: applying a release coating to the inner bottom surface of a mold; applying a transparent gel coat on said release coating; placing a piece of porous flexible sheet material bearing said design on one face thereof on the gel coat in the mold, with said one face toward the gel coat; smoothing said piece of sheet material on said gel coat to contour it to the surface of the gel coat and to remove any air trapped beneath it, with any such air escaping up through the porous sheet material; casting a hardenable marble mix in the mold over the piece of sheet material; and allowing the marble mix to harden for removal of the resultant synthetic marble slab from the mold, said piece of sheet material being inlaid in the slab with the design viewable through said transparent gel coat.
Claim 3
Dependent Claim
18 words
A process as set forth in claim 1 wherein said transparent gel coat is approximately 0.010-0.20 inches thick.
Claim 4
Dependent Claim
30 words
A process as set forth in claim 1 wherein said piece of flexible sheet material is smoothed on the gel coat in the mold prior to gelation of the latter.
Claim 5
Dependent Claim
28 words
A process as set forth in claim 3 further comprising the step of allowing said gel coat to gel prior to casting the marble mix in the mold.
Claim 6
Dependent Claim

Dependent Claim
17 words
A process as set forth in claim 4 wherein said sheet material is approximately 0.001 in. thick.
Claim 8
Dependent Claim
51 words
A process as set forth in claim 1 further comprising the steps of allowing the gel coat in the mold to gel and then coating with a transparent gel said one face of the piece of sheet material, all prior to smoothing the piece of sheet material on said gel coat.
Claim 9
Dependent Claim
36 words
A process as set forth in claim 7 further including the step of allowing the gel on said one face of the piece of sheet material to gel before casting the marble mix in the mold.
Claim 10
Dependent Claim
16 words
A process as set forth in claim 8 wherein the sheet material is a stretchable cloth.
Claim 11
Dependent Claim
16 words
A process as set forth in claim 9 wherein the cloth is a polyester knit cloth.
