Process for manufacturing glass craft by using ceramic mold

Abstract

The invention discloses a process for manufacturing a glass craft by using a ceramic mold. The process comprises the following steps: (a) preparing an ordinary ceramic tile and washing the ordinary ceramic tile; (b) engraving required patterns in the surface of the ceramic tile by hands or laser; (c) putting the manufactured ceramic mold into a furnace, sweeping the surface of the ceramic mold with a bristle broom to remove dust, spraying a mold releasing agent or isolating powder on the surface of the ceramic mold; (d) cleaning a piece of glass, irradiating the tin coating of the glass with a lamp, putting the glass in the furnace, wherein the glass is put on the ceramic mold with the tin coating upward; and covering the furnace with a furnace cover; (e) starting the furnace for casting, increasing the temperature of the furnace to 700 DEG C, and keeping the temperature at 700 DEG C for 25 minutes (f) decreasing the temperature of the furnace to 60 DEG C and shutting down the furnace; and (g) taking the product out of the furnace. The repeated utilization factor of the mold is high and the manufactured glass craft has a good effect.

Description

technical field [0001] The invention relates to glass handicrafts, in particular to a process for making glass handicrafts using ceramic moulds. Background technique [0002] Glass handicrafts, also known as glass handicrafts, are products with artistic value made by processing glass raw materials or glass semi-finished products by hand. They are often used as decorative materials or high-end business gifts, and have a good effect on decorating and beautifying the indoor environment. The majority of consumers love. [0003] Glass handicrafts generally need to form various beautiful patterns on the glass by heating up the furnace and die-casting, which requires the use of molds, while sand molds are generally used in traditional technology. The production process is relatively complicated, the mold reuse rate is not high, and the produced glass handicrafts may have defects such as sand spots, which can no longer meet the needs of mass production.
