Sand-blasting treatment for cultery made of stainless polished metal. In contrast with the metal part of the cultery, the lower part thereof is plastified with liquid insulation material. Cultery is placed into a special sand-blasting chamber to be treated for 3 to 6 seconds with special sand along their arm (non-plastified region) by means of a gun (BECK). The advantage of said invention is that the arm of the cultery acquires a high-quality mat appearance; finally, cultery is not shining but endowed with a mere transparent tone. |
