A process for producing two decorative articles including, for example, a flower or plant container or holder, from a single rock, in which a core drill bit is used to drill into the rock to produce a cylindrical core, and the core is then removed from the rock to leave a cavity in the rock so that the rock becomes a decorative container suitable for accommodating a plant or flowers. The core itself is polished to provide a further decorative article, and may also be drilled to suit it for use as a candle holder or cut flower holder. The invention also provides apparatus for performing the core drilling, including an enclosure having walls capable of surrounding the rock, and clamps within the enclosure for firmly holding the rock during the drilling. The walls may be fixed to a cement or concrete floor which also carries the drill.
Procédé utilisé pour fabriquer deux types d'articles décoratifs, notamment un pot à fleurs ou à plantes, à partir d'une roche dans laquelle on perce un trou cylindrique à l'aide d'une mèche de forage. Le trou est évidé de manière à former une cavité dans la roche, qui devient alors un contenant décoratif pouvant recevoir une plante ou des fleurs. La surface de la cavité peut être polie pour constituer un autre article décoratif et être percée en vue de former un bougeoir ou un contenant pour fleurs coupées. La présente invention porte également sur un appareil utilisé pour forer le trou. Il se compose d'un boîtier, dont les parois entourent complètement la roche, et de pinces intérieures qui retiennent fermement la roche pendant le forage. Les parois peuvent être fixées à un plancher de ciment ou de béton sur lequel sera également installée la foreuse.
