The hand blowing glassware is divided into two kinds: rotary blowing and static blowing. The former one is to blow into a large bubble into a certain shape of the mold, and then blow it evenly while rotating the steel pipe that carries hot glass. Static blowing is to put the big bubble into a certain shape of the mold, do not make rotary blow molding. 

Rotary blowing method is mainly used for the production of round water cups, vases and other products; The static blowing method is mainly used for blowing thin-walled products with different geometrical shapes and surfaces with embossed or debossed patterns, such as square and curved products. The surface of those glassware produced by rotary blowing method is smooth, you can not see the mold of the suture, its appearance is more beautiful. 

static blowing method of blowing products, because in the mold blowing does not rotate, so the product can be clearly seen in the mold of the stitching, the appearance is not as smooth as that of rotary blowing glassware, but we can make debossed or embossed logo on its surface,which is everlasting on the glass cup
