After being polished and polished, the nested glass bottle products are very beautiful because of the color and the base glass. They are commonly used to produce high-grade art glassware, and the nesting materials are generally blow molded.
On white transparent glass, one or two layers of color glass or opaque glass are generally referred to as nestings.
First, pick a colorless material to make a small bubble. After it is slightly cold, smear the coloring material in another sputum, then roll the blister in the usual way and blow it into a shape. This method is simple and easy, but the disadvantage is that the color layer is not uniformly distributed, which makes it difficult to grind a deep colored glass product.
The color glass is blown into a bowl shape, and then the color glass bowl-shaped outer skin is adhered with a colorless glass frit so that the color layer can be evenly distributed. Sometimes a multi-layer nesting is required. The first layer is colorless, the second layer is milky white, the third layer is color, and the fourth layer is colorless.
