Abstract
Abstract Cultured onyx, cultured marble, and like mineral-appearing products are provided, as well as intermediates and components and methods therefor through the combination of a locally discontinuous phase comprising a synthetic organic resin portion hardened to a predetermined hardness and a visually distinguishable continuous phase comprising a synthetic organic resin portion separately hardened to the predetermined hardness with the discontinuous phase intimately distributed therein, to form shaped structures having surfaces simulative of onyx, marble, or like naturally occurring mineral in appearance, which surfaces are uniformly polishable in phase undifferentiated relation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
76 words
The method of manufacturing a cultured onyx, cultured marble, or like mineral-appearing surface structure which includes combining with a first hardenable synthetic organic resin portion, a second visually distinguishable pre-hardened particulate synthetic organic resin portion, said first resin portion being hardenable to a like hardness to said second resin portion, hardening said first resin portion with said second resin portion distributively disposed in situ therein to said like hardness in the desired form of said structure.
Claim 2
Independent Claim
76 words
The method of manufacturing a cultured onyx, cultured marble, or like mineral-appearing surface structure which includes combining with a first hardenable synthetic organic resin portion, a second visually distinguishable pre-hardened particulate synthetic organic resin portion, said first resin portion being hardenable to a like hardness to said second resin portion, hardening said first resin portion with said second resin portion distributively disposed in situ therein to said like hardness in the desired form of said structure.
Claim 3
Dependent Claim
22 words
The method according to claim 1, including also, adding colorant, hardening said second resin portion and triturating to the desired size particulate.
Claim 4
Dependent Claim
22 words
The method according to claim 2, including also polishing the surface of the structure to a gloss in gel coat free relation.
Claim 5
Dependent Claim
55 words
The method according to claim 2, including also hardening a polyester resin as said second resin portion, triturating the hardened resin portion to a particulate mass having an average mean particulate size diameter of less than about 50 U.S. mesh and combining said second resin portion with a first resin portion comprising hardenable polyester resin.
Claim 6
Dependent Claim
32 words
The method according to claim 1, including also proportioning the first and second resin portions so that the said second resin portion constitutes from 25% to 50% of said structure by weight.
Claim 7
Dependent Claim
41 words
The method according to claim 1, including also depositing said combined resin portions into a structure-defining form prior to hardening of said first resin portion, and thereafter hardening said first resin portion with said prehardened second resin portion distributively disposed therein.
Claim 8
Dependent Claim
24 words
The method according to claim 6, including also maintaining a passage within said combined resins during hardening of said first resin into a structure.
Claim 9
Dependent Claim
29 words
The method according to claim 7, including also disposing a preformed passage-defining element in said combined resins prior to hardening of said first resin to maintain a passage therewithin.
Claim 10
Dependent Claim
23 words
The method according to claim 6, including also disposing a preformed element in said combined resins prior to hardening of said first resin.
Claim 11
Independent Claim
69 words
The method of manufacturing a cultured onyx, cultured marble or like mineral-appearing structure, which includes confining in a forming zone a previously hardened, particulate polyester resin, a colorant, and a visually distinguishable, liquid, hardenable polyester resin in distributively commingled relation and in such relative proportions as to provide an onyx, marble or other mineral simulative surface appearance, and hardening the hardenable portion while confining the resin within said zone.
Claim 12
Independent Claim
69 words
The method of manufacturing a cultured onyx, cultured marble or like mineral-appearing structure, which includes confining in a forming zone a previously hardened, particulate polyester resin, a colorant, and a visually distinguishable, liquid, hardenable polyester resin in distributively commingled relation and in such relative proportions as to provide an onyx, marble or other mineral simulative surface appearance, and hardening the hardenable portion while confining the resin within said zone.
Claim 13
Dependent Claim
9 words
The product made by the method of claim 10.
