铜红釉的科学研究——由钧窑说起

On Scientific Study of Copper-red Glaze

铜红釉以铜的氧化物作为着色剂还原烧成。钧窑创造性地使用铜的氧化物作为着色剂,在还原条件下烧制出窑变铜红釉,并由此繁衍出多种窑变色彩,彻底改变了以往青釉类瓷器的单色格局。铜红釉主要包括钧红、祭红、钧红花釉、郎窑红、三阳开泰、美人醉、郎窑花釉、玫瑰紫、火焰红、釉里红等。铜红釉的各种基础釉料对呈色有不同的影响,还原气氛的轻重、还原时间的长短、温度的高低对釉面色调的影响更为关键,必须对这些因素严格掌握和控制。

The reductive firing of copper-red glaze is based on the use of copper oxide as colorant. By using cop- per oxide as colorant creatively, furnace transmulation copper-red glaze of Jun kiln can be obtained and various furnace transmulaiton colors can also be generated, which totally changed the single color of green glaze china. Different basic glazes may produce different influence on color generation, and reducing atmosphere, reduction time and the temperature all play critical roles in the generation of glaze hues. Therefore, a strict and careful control of these factors should be exercised.
