How to make glass crafts

is blown glass, and the other is blow molding. It is to take out an appropriate amount of glass solution, put it on one end of the iron blowing tube, blow it while rotating, and use a pair of scissors or pliers to form it.

many kinds of. The main component is sodium silicate; potassium glass, the main components of glass are strontium sand, soda ash, sodium carbonate, potassium carbonate, lime and alumina, lead dan and so on. Bottle glass belongs to it; lead glass, instrument glass belongs to it. The meteorites in the Hsinchu area are produced in the Kansai area. However, in recent years, the iron content is high and the quality is slightly poor, so most of them are still imported from Australia and Malaysia. First, sand, lime, soda ash, etc. are placed in a crucible kiln at a high temperature of 1,450 degrees Celsius for 16 hours. After being mixed and melted into a thick liquid, it is placed on a mold to form it. After 12 hours of cold, add and treat. During the period, sandblasting, coloring, embedding gold foil, grinding, carving, immersion and other decorative techniques are applied. In addition, various metal coloring agents are used in the firing, and the glass which is produced has just a different color.

Glass forming method:

In order to make it cool and form, the glass generally forms a liquid viscous liquid after combustion and dissolution of the glass raw material. Most of them use the type of blowing method, using various materials, such as wood, clay, metal, etc., to pre-form the required type of material, pour the molten glass into the model, and then open the model after cooling, generally Appliances that cannot be made by blowing glass are used in most factories and can be mass produced.
