Most glass crafts are made by blowing glass, and another type is formed by blowing. Take an appropriate amount of glass solution and place it on one end of the blowing iron tube. At the same time, blow air and rotate it, skillfully shaping it with scissors or pliers. Now let’s take a look at how to make glass cup handicrafts.
glass
There are many types. The main component is sodium glass; Potassium glass is mainly composed of silica sand, soda ash, sodium carbonate, potassium carbonate, lime, bauxite, lead, etc. Glass bottles belong to; Lead glass, instrument glass. The siliceous rocks in the Hsinchu area are produced in the Kansai region, but in recent years, their iron content has been high and their quality has been slightly poor. Most of them are still imported from Australia and Malaysia. Firstly, silica sand, lime, and soda ash were put into a crucible kiln at ℃ for 16 hours in 1450. Mix and melt them into a thick liquid, then place them on the mold to form. Then, slowly cool for 12 hours before adding. During this period, decorative techniques such as sandblasting, coloring, inlaying gold foil, grinding flowers, carving, and soaking in medicinal solution were adopted. In addition, various metal colorants were used during the firing process, resulting in glass with different colors.
Glass forming process:
Glass is formed to cool it, usually forming a liquid viscous liquid after the combustion and dissolution of glass raw materials. Mainly using blow molding method. Models made of various materials, such as wood, clay, metal, etc., are used to make the required molds in advance. Pour the molten glass into the model, cool it down, and then open the model. It is usually used for vessels that cannot be blown with glass. Most factories adopt this method and can produce in bulk.
