Wooden shape

from Wikipedia, the free encyclopedia

The glassmaker uses a wooden mold to create the raw shape for a glass productset. The glowing glass is blown or poured into the mold and thereby shaped. The forms can be in several parts. To prevent the wood from burning, the mold is soaked in water before it is used. The wooden mold is repeatedly immersed in the water between individual production processes. A layer of charcoal forms on the inner wall of the mold, which is particularly good at storing water. When the glowing glass is brought in, the water forms a layer of vapor that gives the glass its smooth surface. The wooden mold still burns out with every use, so that only a very limited number of glasses can be produced with one mold. After that, the mold is burned out. Molds for blowing in often do not completely enclose the glass. The glass is rotated when blowing in them.
