What is the manufacturing process of glass lampshade

1. Reclaiming

Pick up the preheated blowpipe and go deep into the 1300-degree crucible furnace, not too greedy, not too little. Just the right ball of hot glass, attached to the blowpipe with the heat, sunglasses, headscarf, fully armed, ready to turn your blowpipe, over and over again.

2. Forming

Put the obtained material into the mold, luck, blow the air into the glass through the iron pipe, and hold it out.

3. Edging

The edge of high-quality glass will not cut your hands if you touch it by hand. Of course, because of the increase in this process, the price of the product is also different, because the loss of this process is very large.

4. Annealing

The glass cannot be allowed to cool down naturally, because when its surface is cooled by air and shrinks, the inside expands due to the retention of heat, and rapid cooling will cause uneven pressure and cracks.
