## Abstract

A method for impregnating rock or mineral with scented and/or colored fluid. To impregnate the rock or mineral with scented fluid, the rock or mineral is heated to dehydrate it, and cooled to an ambient temperature in a dehumidified chamber, and then placed in a pressurizable container which is filled with scented fluid. The pressurizable container is placed under pressure for a sufficient time that the scented fluid is forced into the interstices of the rock or mineral. When the rock or mineral is removed from the pressurizable container, it has been impregnated with scented fluid and emits a pleasant odor. The rock or mineral may be cleaned using water or a solvent.

## Claims

### Claim 1

A method of impregnating a hydrated or porous rock or mineral with a scent, which comprises:
(a) dehydrating the rock or mineral;
(b) cooling the rock or mineral to an ambient temperature in a dehumidified chamber;
(c) placing the rock or mineral in a pressurizable container;
(d) filling the pressurizable container with a scented fluid;
(e) pressurizing the container for a preselected period of time, and at a preselected pressure to impregnate the rock or mineral with the scented fluid;
(f) depressurizing the container;
(g) removing the scented rock or mineral from the pressurizable container.

### Claim 2 (depends on 1)

The method of claim 1, wherein the rock or mineral is cleaned with a solvent after being removed from the vacuum.

### Claim 3 (depends on 2)

The method of claim 2, wherein the solvent used to clean the rock consists of an alcohol.

### Claim 4 (depends on 3)

The method of claim 3, wherein the scented fluid consists of an aqueous solution of water plus a scenting agent.

### Claim 5 (depends on 1)

The method of claim 1, wherein the rock or mineral is dehydrated in a dehydrating chamber.

### Claim 6 (depends on 5)

The method of claim 5, wherein the dehydration step takes place in a sintered container.

### Claim 7 (depends on 5)

The method of claim 5, wherein the dehydrating chamber consists of a vacuum oven.

### Claim 8 (depends on 5)

The method of claim 5, wherein the scented fluid is also colored.

### Claim 9 (depends on 1)

The method of claim 1, wherein the rock or mineral is heated to approximately 220.degree. F. to dehydrate the rock or mineral.

### Claim 10 (depends on 1)

The method of claim 1, wherein the scented fluid consists of an organic solution of an oil and a scenting agent.

### Claim 11 (depends on 1)

The method of claim 1, wherein a hydraulic cylinder is used to pressurize the scented fluid and rock or mineral.

### Claim 12 (depends on 1)

The method of claim 1, wherein the container is pressurized to within the range of 1000 to 1500 p.s.i.

### Claim 13

A method of impregnating a hydrated or porous rock or mineral having a rock or mineral matrix, with a scent which comprises:
(a) placing a rock or mineral in a container;
(b) dehydrating the rock or mineral;
(c) filling the container with a scented fluid;
(d) pressurizing the container for a preselected time and at a preselected pressure to impregnate the rock or mineral with a scented fluid;
(e) depressurizing the container;
(f) removing the rock or mineral from the container.

### Claim 14

A scented rock or mineral which comprises:
a dehydrated rock or mineral having pores; and
scented fluid impregnated into the pores of the rock or mineral.
