Forming Method Mold Blowing
Mold blowing employs the same process as blowing, except the final form is achieved by blowing the prepared glass into some type of mold or formwork. The mold can be made from a variety of materials, such as plaster-silica, plywood, cherry wood, graphite, iron, copper and bronze. Some detail is lost when glass is blown, and the mold may not have any undercuts. The mold needs to take into account the moil, or "neck," left after the glass has been blown. The moil is the result of allowing space within the mold for the blowpipe to enter. After the piece has annealed, the moil is cut off in the cold shop using a diamond saw. |
