Abstract

A method of forming a simulated combustible fuel element including covering at least a part of a surface of a master with a material selected to produce a mold, and then removing the master from the mold. A predetermined amount of a liquefied body material that is less than a volume of the mold is introduced into the mold. A body including the body material is produced with one or more cavities therein and an exterior surface simulating at least the part of the surface of the master. The body material is allowed to solidify, at least to the extent that the body material is self-supporting, and the mold and the body are separated. One or more fuel light sources are positioned to direct light therefrom in the cavity. At least a portion of the exterior surface is coated so that the portion simulates a combustible fuel element.

Claims (42)

1. A method of forming a simulated combustible fuel element comprising:

(a) covering at least a part of a surface of a master with a material selected to produce a mold defining a volume therein;

(b) removing the master from the mold;

(c) introducing a predetermined amount of a liquefied body material into the mold that comprises less than the volume of the mold;

(d) producing a body comprising said body material and at least partially resembling the master, the predetermined amount being sufficient to provide the body with at least one cavity therein and an exterior surface simulating at least said part of the surface of the master;

(e) allowing said body material to solidify, at least to the extent that said body material is self-supporting;

(f) separating the mold and the body;

(g) positioning at least one fuel light source to direct light therefrom in said at least one cavity; and

(h) coating at least a portion of the exterior surface such that the portion simulates a combustible fuel element.

2. A method according to claim 1 in which the mold is resiliently flexible.

3. A method according to claim 1 additionally comprising, after step (f), the step of forming an access hole in the body in communication with said at least one cavity, to permit said at least one fuel light source to be at least partially inserted in said at least one cavity through the access hole.

4. A method according to claim 3 additionally comprising, after said at least one fuel light source is at least partially positioned in said at least one cavity, the step of inserting plug material into the access hole to substantially block the access hole.

5. A method according to claim 1 in which the material of step (a) is silicone rubber.

6. A method according to claim 1 in which said at least one light-transmitting part is colored reddish.

7. A method according to claim 1 in which the light from said at least one fuel light source is reddish.

8. A method of forming a simulated combustible fuel element comprising:

(a) covering at least a part of a surface of a master with a material selected to produce a resiliently flexible mold defining a volume therein;

(b) removing the master from the mold;

(c) introducing a predetermined amount of a liquefied body material into the mold that comprises less than the volume of the mold;

(d) producing a body comprising said body material and at least partially resembling the master, the predetermined amount being sufficient to provide the body with at least one cavity therein and an exterior surface simulating at least said part of the surface of the master;

(e) allowing said body material to solidify;

(f) separating the mold and the body;

(g) positioning at least one fuel light source to direct light therefrom in said at least one cavity such that light from said at least one fuel light source is transmittable through the cavity, to resemble glowing embers of the combustible fuel at the exterior surface.

9. A method according to claim 8 in which the body comprises at least one light-transmitting part through which the light from said at least one fuel light source is transmittable to simulate glowing embers.

10. A method according to claim 8 in which the body comprises at least one aperture through which the light from said at least one fuel light source is transmittable.

11. A method according to claim 8 in which at least a portion of the exterior surface of the body is coated in accordance with a predetermined exterior surface pattern such that the portion of the exterior surface resembles the surface of the master.

12. A method according to claim 8 additionally comprising, after step (f), the step of forming an access hole in the body in communication with said at least one cavity, to permit said at least one fuel light source to be at least partially inserted in said at least one cavity through the access hole.

13. A method according to claim 12 additionally comprising, after said at least one fuel light source is at least partially positioned in said at least one cavity, the step of inserting plug material in the access hole to substantially block the access hole.

14. A method according to claim 8 in which the material of step (a) is silicone rubber.

15. A method according to claim 8 in which the light from said at least one fuel light source is reddish.

16. A method of forming a simulated combustible fuel element comprising:

(a) covering at least a part of a surface of a master with a material selected to produce a resiliently flexible mold defining a volume therein;

(b) removing the master from the mold;

(c) introducing a predetermined amount of a liquefied body material into the mold that comprises less than the volume of the mold;

(d) producing a body comprising said body material and at least partially resembling the master, the predetermined amount being sufficient to provide the body with at least one cavity therein and an exterior surface simulating at least said part of the surface of the master, the body comprising at least one light passage;

(e) allowing said body material to solidify;

(f) separating the mold and the body;

(g) coating at least a portion of the exterior surface of the body to simulate at least said part of the surface of the master; and

(h) positioning at least one fuel light source to direct light therefrom in said at least one cavity such that said at least one light passage is located in a path of light from said at least one fuel light source, said at least one light passage resembling glowing embers of the combustible fuel upon transmission therethrough of light from said at least one fuel light source.

17. A method according to claim 16 in which said at least one light passage comprises at least one light-transmitting part.

18. A method according to claim 16 in which said at least one light passage is located at a translucent portion of the body.

19. A method according to claim 16 in which said at least one light passage comprises at least one aperture extending between the exterior surface and said at least one cavity.
