The original method should be to manually blow the glass, use a stainless steel hollow tube to pick an appropriate amount of high-temperature molten glass water, blow it into a spherical shape like blowing a balloon, and then put it into the prepared mold and continue to blow it into the same shape. The mold fits the shape of the mold, then open the mold, use a clip to clamp the cup into the annealing kiln to remove the stress of the glass, and then cut, edge, install (foot or handle), and polish to get the finished double layer. glass.
The principle of machine blowing glass is the same as that of manual work, except that it is blown by a human blower into a bubble blower.

There is a punch hanging above to be fixed. The glass water drops into the mold, and then turns to the bottom of the punch when the punch falls to press the glass into shape, and then takes it out manually and puts it into the annealing kiln, and the finished double-layer glass comes out.

Of course, if you have some special requirements for the glass, you can also customize one to make the glass meet your own preferences.
