How do crystal glass products

Glass main ingredient is silica sand, soda ash, sodium carbonate, potassium carbonate, lime and bauxite, lead, Dan, a lot of species. Generally the main ingredient is sodium glass genus; potassium glass, bottle glass genus; leaded glass, instrument glass genus. Hsinchu area silica produced in the Kansai area, but in recent years, the high content of iron parts, quality bit weak, so most still in Australia and Malaysia imports. After the first of the first silica sand, limestone, soda ash, etc. into the crucible kiln, under one thousand four hundred fifty degrees Celsius temperature 16 hours melt into a thick liquid to be mixed, placed in the mold, shaping, After twelve hours and then slowly cooled after adding Processing. Imposed during sandblasting, add color, embedded gold, wear flowers, sculpture, soaking syrup and other decorative techniques. And various metals in the firing agent color, having just made out of glass of different colors.

Lu Yi glass forming method:

Glass materials are generally formed of glass after burning liquid viscous solution was dissolved, cooled to molding, the most used type of blowing method using models of various materials, such as wood, clay, metal, prefabricated type is required, the melted glass was poured into the model, the model to be cool before opening Serve, generally used for appliances not made of blown glass, most of the factories are using this method, can be mass produced.

Another is a blow molding method, namely blown glass, glass solution is to remove the right amount, put at one end of the iron blowpipe, blowing side, while rotating, and skillful techniques, the use of scissors or pliers to molding.

Production Act of cold work

1. Painted with paint pigments, at room temperature at the surface of the glass pictures depicting some fixing to be heated, and some without. Process can also be coupled gold, silver into the molten metal pigment called decorated with gold painted.

2 glaze is a need to add vivid color temperature techniques in the glass surface to draw the pattern glaze pigments, and then placed in a furnace heated fixed pigment to avoid peeling.

3 of grooves inlaid with leaded wire frame is a combination of thousands of pieces of colored glass techniques, the need to draw a small plan, according to the plan drawn sketches, such as the size of each color to determine the shape and size, cut glass right to the lead wire welded into large mirror.

4 prints the cold without heating, the use of sandblasting and grinding techniques, the figure engraved on the glass, to the plate, or drum machine to print color in tissue paper or watercolor paper pressed into prints.

5. Relief in two or more layers of glass nesting color, three-dimensional relief pattern revealing the background, forming a relief effect.

6 Cut the use of cutting wheels, cutting decoration, block surface, lines on glass and other decorative objects, or Omo cut shape, color and sometimes nesting glass, because the performance of different colors inside and outside of special effects.

7 and grinding with diamond or metal sculpture, carving or engraving pen tool to draw lines on the glass surface decorative pattern and pattern techniques, due to the use of tools can be divided into round engraved, stippling, and other types of flat engraved techniques.

8 etched graphics rendering, sketched lines in the glass, and then chemically etching the acid phased out different shades of patterns.

9 prior to the tape span a sand glass composition, in order to remove the cutter engraved pattern plating unnecessary part, into the blasting machine, the use of high ejection force emery make fog effects in the glass.

10. Grinding wheel is a rotating grinding table, mixing water and carborundum, glass polished planed work.

11 Planing leather wheel to rotate the platform, as for the glass on it, polished planed chunk plane.

12. Glue will work into the heating furnace, the use of the characteristics of the glass, heated to melt the surface brightness.

13 adhesive glue to be bonded into the glass block shape.

14 mixed media using glass and other materials group creation.

Thermal production method

(The melting point (1450 degrees) and Xu cold spots (450 degrees) between the production method, called thermal)

1 compression molding molten hot glass paste injection pressure has been carved into a good pattern mold becomes blocky patterns while also suppress the good.

2 sand casting the model of moderate indentation depth to wet sand sand mold acetylene avoid caving in to the glass paste into a sand mold to be removed and then slowly cooled glass coolish after grinding.

3 embryo heart shaped one of the earliest techniques used to make glass window first hybrid embryos made of mud and horse manure outside the pericardium and then picks up the metal rods become hot glass cream container body, figure out the pattern outline around the glass, and other cold-finished Xu After dug embryo heart is complete.

4 lights in a small gun or torch lights thermoplastic heating torch to help light the torch, also known as thermoplastic, with only color or colored borosilicate glass soda glass color rods to stretch, twist, wound and other techniques, the continuous combined into shape for tiny delicate performance, such as glass beads, animals and plants. Because of the use of a glass rod into different zones: solid, hollow and drawing thermoplastic, in addition, can be used with painted more interesting work.

5 blown originated the first year of the Roman Empire in AD, and now is still the most important glass technology, the most widely used, up to changing production methods. Blown mostly window-based, process refers to the blowpipe picks molten glass paste, inflatable form small bubbles, then use the tool to thermoplastic molding, then picks up another small glass blowpipe end action for bridging connection, Qiaoxia works of Xu cold.

6 After using the lost-wax casting refractory plaster wrap wax mold, raw materials and empty glass in the mold into the oven while heating at high temperature glass slowly into the molding, lost wax placed in a furnace, Xu cold removal of the cast, and then grinding planed completed.

7. Powder casting glass block and glass powder fill predesigned models, into a furnace heated molten glass into the whole works.

8 Design heating furnace is between 750 degrees to 850 degrees heat production techniques.

9 thermoplastic fusion will be a combination of chopped glass or glass ceramic different pattern on the plate into a furnace heated to become a glass version will usually be used with other techniques to change.

10. Curved glass material was first put on a good design modeling clay heated glass gradually softens and begins to sag can freefall molding.
