How to make glass tea set
Put the powder and clinker mixed according to the glass composition into the crucible kiln or pool kiln (see glass melting kiln) for melting, after melting, clarify into a uniform glass liquid without bubbles, stones and streaks, and then cool to suit The viscosity range required by the molding method allows for various molding operations.
There are two methods of manual and mechanical blow molding. During manual molding, a hand-held blow pipe picks material from the crucible or the kiln feed port, and blows it into a shape in an iron or wooden mold. The smooth and round products use the rotary blow method; the products with convex and concave patterns on the surface or the shapes that are not round are used the static blow method. First pick the colorless material to blow into small bubbles, and then use the small bubbles to pick up the color material or the opacified material to blow into the shape of the device is called sleeve blowing. Dip the color fusible material particles on the opacifying nesting material, and the natural melt flow of each color can be blown into a natural scenery utensil; dipping the ribbon-shaped opacifying material on the color material can be blown into a brushed utensil. Mechanical forming is used to blow large quantities of products. After the blowing machine receives the material, the iron mold is automatically blown into a device shape, and the cap is removed after demolding to form a vessel. Press-blow molding can also be used, the material is first blown into small bubbles (prototype), and then continue to blow into the shape of the device. It has higher efficiency and better quality than blowing with a blowing machine alone.
During manual molding, the material is manually picked and cut into the iron mold, the punch is driven, pressed into the shape of the machine, and the mold is released after setting. The automatic production of mechanical forming has large batches and high efficiency. Compression molding is suitable for small-sized products with large bottoms that can withdraw from the punch, such as cups, plates, and ashtrays.
The material is received in the rotating mold. The centrifugal force generated by the rotation causes the glass to expand and adhere to the mold. It is suitable for forming large glassware with uniform walls.
Also known as moldless molding. Use artificial picking materials to repeatedly bake and modify or thermally bond in front of the kiln. Because it is not in contact with the mold, the glass surface is bright, and the shape of the product is smooth. The finished product is also called kiln glass product.
