The Difference Between Manual Blowing and Machine Blowing of Glassware

Some friends who are interested in the glass industry, may often hear about machine blowing glassware. We often encounter machine blowing glassware, but because many people don’t know much about the glass industry, all sorts of problems arise around it. We’ve compiled this article to help you get a better understanding of blowing glassware and solve your problems.

1.The Difference Between Manual Blowing and Machine Blowing of Glassware


If it is a water cup, it can be distinguished only by the joint line and the thickness of the cup wall. Generally, there is no joint line in the cup when it is blown manually, and most of the cups have thin walls with slight bubbles and streamlines, and the sizes are slightly different.

If it is a goblet: for domestic glassware, the mechanism is thick and straight, with thick wall, and the cup shape is small, so it looks relatively heavy (or rather heavy). However, the cup made by hand is thin and thin, with many shapes and looks more delicate. Of course, there may be bubbles and streamlines.

If it is a foreign well-known brand of goblet, the mechanism of the cup is better than artificial blowing: thin, thin wall, no bubbles, streamline, modeling and other aspects are no different from artificial blowing.

2.Types of Glassware Blowing Process

According to the processing method is divided into heat treatment and cold treatment;

According to the effect can be divided into mouth processing, bottom processing, texture effect, combination and paste, and other material combination, grinding, carving and decoration.

Mouth treatment mainly includes: opening, Fried mouth, cabbage mouth/flower mouth/socket mouth/oval mouth/mouth deformation, cutting mouth/crushing mouth, pulling mouth, skirt hem mouth, drawing mouth/small turning mouth, flanging mouth, cutting mouth, small drying mouth, pouring die mouth, blasting drying mouth, mouth winding silk/winding ring.

Bottom treatment mainly includes: pump bottom grinding, big bottom grinding, bowl pump, pinch pump, drilling hole.

The color materials mainly include: plain, porcelain cover/white porcelain inside and outside of two colors, wrapped silk/wide band/sticking point/hook wire, color material transition port, two-color transition, three-color cylinder, beach material sticking piece, cover leather/covering material, inserting silk, color material reducing silk, hand-kiln glass, jade material/check pattern.

Porcelain powder mainly includes: internal adhesion/external adhesion, mixed porcelain powder, porcelain powder tape/silk/point, ballast point/big glass piece, porcelain powder and alkali external adhesion archaize, external adhesion reduction, porcelain powder iron plate flower, mixed ballast hook wire (wood grain), color powder.

Texture effects mainly include: outer wrapping ring/outer wrapping coarse silk, internal and external hair edge, inner optics (Yin and Yang mold)/outer optics, rose thorn, pineapple thorn/moon ring, porcelain powder water deep-frying/point deep-frying, sticky flower head/glass flower, sticky flower dot material, nail mold bubble/dense nail mold, pressing pit, cold spot, drilling hole and blowing.

The combination paste mainly includes: cold stick, hot stick, sticky ear/handle, cap container, pile cover, double eyelid, flat, solid candlestick, hollow candlestick, perforated rivet (for multi-material combination, plate, etc.).
