1. Composition difference:
The main components of lime glaze are calcium oxide and calcium carbonate, while the main components of plant ash glaze are calcium oxide and calcium carbonate. In addition, plant ash glaze also contains a small amount of silicate.
2. Appearance difference:
The appearance of lime glaze is usually brighter than that of plant ash glaze, because its glaze contains more metal ions. The appearance of plant ash glaze is dim because it contains more calcium and silicate.
3. Corrosion resistance:
The corrosion resistance of plant ash glaze is better than that of lime glaze, because it contains more silicate and can better resist the corrosion of corrosive substances such as acid and alkali.
4. Crack resistance:
The crack resistance of lime glaze is better than that of plant ash glaze, because it contains more calcium oxide and can better resist hot cracking.
In a word, lime glaze and plant ash glaze are common ceramic glazes, and they are different in composition and appearance. When choosing which glaze to use, you need to choose according to the specific requirements and uses.
