The resulting glass, heated to a higher temperature than standard glass, becomes much more heat resistant and shock resistant. Each teapot is formed by hand from a thick glass tube. The blowing is mechanised. The body is first formed by blowing and stretching by hand over a torch. Then the details are executed one by one with tongs and by turning over the flame.
