Last week, we learned about the free blowing. Now, let us know the mold blowing together.
During the first part of the second quarter of the 1st century AD, mold-blowing became an alternative glassblowing method. Firstly, a glob of molten glass is placed on the end of the blowpipe, and is then inflated into a wooden or metal carved mold. Therefore, the shape and the texture of the bubble of glass is determined by the design on the interior of the mold, which is highly different from free molding. Free molding is based on the skill of the glassworker.
There are two types of molds, single-piece mold and multi-piece mold, which are frequently used to produce mold-blown glass products.
