Honeycomb nuggets measure approximately 13.3 x 9.3 cm. Blank solder plates measure approximately 14.5 x 11 cm. Suitable for handmade jewelry. Please check the refractory specifications before purchasing. Brick size information: The honeycomb jewelry making board is primarily made of ceramic, resistant to temperatures up to 1450 degrees Celsius. The other board is primarily made of quartz, resistant to temperatures up to 1700 degrees Celsius. Both materials are heat resistant, durable, and long lasting. Our jewelry welding kit can be widely used in jewelry making and also serves as an auxiliary tool for jewelry repair, metal welding, and similar applications. Slight surface cracks may appear on the refractory bricks; this is normal due to the material properties and does not affect performance. Handle the board with care during transport and use.
