Lengthy Production Procedures: The production of a finished glass handicraft usually involves numerous elaborate and complicated manual procedures, including material selection, ingredient mixing, crushing, clay preparation in the shade, clay mixing, stabilizing work, kiln firing, glaze application and so on. Each procedure needs to be strictly controlled to ensure the precision and stability of the products.
Handmade: The production of glass handicrafts requires workers to master exquisite techniques. Each process has its own variable factors, and repeated experiments are needed during the production process. Therefore, the production difficulty is extremely high.
One Mold for One Piece: Due to the complexity of the production process of glass handicrafts and the heavy reliance on manual operations, one mold can only be used to fire one piece of work and cannot be reused. For large and complex works, it may even be necessary to open molds and fire multiple times to complete them.
High-temperature Firing: The firing of glass handicrafts requires melting carefully selected raw materials into various colored crystal glasses at a high temperature above 1,400 °C. After multiple rounds of careful selection and cleaning, the materials are placed into molds according to the proportion required by the work, and strict heating and cooling curves are set. The furnace temperature must be controlled within 1,000 °C ± 5 °C. The firing process lasts for more than 15 days, so that the crystal raw materials can be precisely refined down to every tiny detail, thus ensuring that the works are delicate, ingenious, three-dimensional, realistic, with flowing and elegant lines and clear shapes.
Never Fading: The colors in glass are formed by high-temperature sintering of various metal oxides, and there will be no aging phenomena such as fading or oxidation.
Full of Bubbles: The bubbles in glass works offer more room for imagination and make the works more lively. It is a common understanding in the field of glass art that bubbles are like the breath of glass
