Generally speaking, the materials of ceramic cups are divided into bone china, magnesia reinforced china, white china and stoneware china. Our most common ceramic cups are mainly made of white porcelain and reinforced porcelain.
Bone china is a raw material containing beef and sheep bone powder. The fired product has better light transmittance, the product has a delicate glaze, and the product is light green. Bone china is a high-grade material.
Strengthened porcelain is a medium and high-grade material second only to bone china. The main raw materials are talc powder, feldspar powder, etc., which are fired in an oxidizing atmosphere at 1350 degrees Celsius. The product is suitable for large temperature difference (between -20℃-240℃), small deformation, high flexural strength (220MPa), good thermal stability, wide firing temperature range (40℃), etc. Its glaze is The frit glaze with high gloss and transparency makes the product high in whiteness, strong in hardness, fine in glaze and good in transparency.
The main raw materials of white porcelain are kaolin and Pengyang porcelain stone powder.
The main raw materials of stoneware porcelain are quartz powder, Mashan soil, etc., and the firing temperature is between 1180 degrees Celsius and 1270 degrees Celsius.
