The quartz box bowl in the kiln is curved and funnel-shaped.Quartz box bowl is one of the earliest shaped boxes in China,which differs from other kiln mouths in that its bottom is pointed,determined by its small ring foot and hat shaped characteristics.What are the features of this product.
1.The previous firing method directly exposed the substrate of building lighting fixtures to open flames,making the surface of building lighting fixtures prone to contamination;The quartz box bowl effectively isolates the lamp from open flames,allowing the lamp to react freely inside and produce mysterious and unpredictable changes on the glaze surface,without being contaminated by other dust.
2.The quartz box bowl has good sealing performance and can effectively control the oxygen intake,allowing the lamp to be fired into porcelain in a uniform high-temperature environment.At the same time,it can avoid a sudden drop in temperature inside the kiln when external cold air enters,which can cause the lamp to shrink and crack.Maintain the internal temperature and keep the atmosphere within a good range.Atmosphere and temperature are decisive factors in lighting a good lamp.If these two factors are well controlled,the quality of the lamp will naturally improve.
3.The shape of the quartz box bowl in the Song Dynasty is peculiar,with a funnel-shaped shape and a pointed bottom.There is a reason for this design.During the heyday of kilns in the Song Dynasty,tea bowls were mainly used for firing,and the shape of tea bowls was basically small with a big mouth and big feet.By using this funnel-shaped pointed bottom,the upper bowl can be more tightly attached to the lamp surface of the next lamp,improving the sealing performance.And it is made of refractory materials,with a thick body and strong load-bearing capacity,which can stack one product after another on the top of the kiln,maximizing the use of space inside the kiln.
The above are the three main characteristics of quartz bowls.Through this article,I believe everyone must have gained new understanding and recognition of quartz bowls.At the same time,I hope this article can provide help to everyone.If you have any other questions,please feel free to contact us at any time.
