Preparation method of glazed Buddhist utensil

Abstract

The invention discloses a preparation method of a glazed Buddhist utensil. The preparation method comprises the following steps of designing a product drawing designing, manufacturing a loam mold, modeling a silicone mold, casting to obtain a wax model and taking out the wax model, repairing the wax mold, manufacturing a plaster mold, removing wax to manufacture a fire-resistant plaster hollow female mold, preparing raw materials, firing at high temperature, stripping the mold, cutting and grinding, refining products, and polishing the products, Wherein the preparation method also comprises a product core mold manufacturing step between the step of repairing the wax mold and the step of manufacturing the plaster mold, and also comprises mold separation and assembly steps between the step of removing wax to manufacture the fire-resistant gypsum hollow female mold and the step of preparing the raw materials. The preparation method is suitable for demolding and firing of large hollow products, reduces residual fingerprints and paint, and adopts a precision annealing process thus products prepared by the preparation method have heat-resistant and cold-resistant capabilities and are not easy to crack.

Description

technical field [0001] The invention relates to a method for preparing a glazed Buddhist vessel. Background technique [0002] Liuli, also known as "Liu Li", refers to a crystal product prepared by using artificial crystals of various colors as raw materials and using a lost-wax casting process. Its colors are flowing and beautiful, and its quality is crystal clear and dazzling. In view of the high appreciation value and collection value of glazed products, the preparation process of glazed products has increasingly become a research hotspot in the field. [0003] The traditional glass crafts generally have the following steps: 1. Design product drawings: draw graphic design drawings according to the creative concept or according to customer needs; ;3. Making silica gel molds (returning silica gel molds): On the surface of the clay mold prototype, evenly coat silica gel layer by layer, and wait for 2 to 4 hours (even for large products, it takes 10 to 24 hours) to solidify...

Problems solved by technology

[0004] However, the glazed Buddhist vessels prepared by the above-mentioned traditional techniques are generally only suitable for making incense burners or solid Buddhist vessels with large openings and single shapes.

However, Buddhist utensils are generally large in size, and if they are solid, they are cumbersome and difficult to carry. However, for relatively complex Buddhist utensils that require a large inner hollow shape and a small opening, the traditional glazed process cannot complete demoulding and firing. Moreover, even if the existing glazed Buddhist ware has been polished, it is easy to leave fingerprints or oil paint on it during the process of taking or frequent use, which will affect the cleanliness and beauty of the external surface of the glazed Buddhist ware; moreover, traditional The process of annealing the material is not precise enough, which makes the glazed Buddhist ware products have low cold and heat tolerance and are easy to crack
