How to make?
•First, the bottle is extracted from one of our furnaces—electric or pot—in which aqueous has been acrimonious to a temperature that ensures bottle assembly with basal flaws (1450—1500). A alarming rod is biconcave into the furnace, and a baby bulk of aqueous bottle is extracted and destroyed into a baby bubble, alleged the close bubble. This balloon (approx. 3cm—10cm in diameter) is the abject for authoritative stemware, tumblers, candleholders, decanters and pitchers. After the close balloon has been blown, it is arrested for flaws, such as baby bubbles, chips, etc., which ability arise in the accomplished artefact later.
•It is again formed into an almost shape. This asperous anatomy is again destroyed into its final appearance in a cast amid beneath ground, which is cooled by circulating water.
•After the basin has been formed in the mold, for stemware, the axis is continued to its adapted breadth and the abject is attached. After the bottle has been destroyed and formed, it is transferred to the annealing kiln, aswell alleged a lehr. During this process, bottle is boring acrimonious and cooled in adjustment to acclimate it and abate brittleness. The annealing anhydrate at Huafu is about 28 meters long, through which glassware passes on a agent belt. The accomplished action from access to avenue takes about 100 minutes, during which the bottle is apparent to temperatures capricious from 540oC in the average of the kiln, to a minimum of 60oC at the avenue point.
•When the bottle exits the annealing kiln, it is accustomed by workers in the cold-working shop. The allotment of the bottle which is candy actuality is the rim, which is fire-cut to an exact height. After getting fire-cut, the rim has to be arena by accomplished beach and water, and again broiled or polished. Rims with a array of 1mm to 2mm are baked, while rims with thicknesses of added than 2mm are polished.
•After the rim has been processed, the bottle is again advised in assorted ways, including cutting, sandblasting, hand-painting (gilding or blush decorating) and decal attachment, all according to our customers’ needs. The exoteric of the bottle can be cut with patterns of all kinds. Decal attachment, blush adornment or beautification requires an added annealing process, during which the advised glassware is beatific through a nine meter-long kiln. For decals, the max temperature in the anhydrate is 600oC; for blush decoration, 540oC- 550oC; and for hand-painting and gilding, 560oC. These assorted analysis processes are important for abacus amount to our products.
