Mutton Fat Jade Porcelain is an ancient material for porcelain-making that is known for its unique texture and exquisite design, making it a popular choice among collectors and porcelain enthusiasts. When identifying Mutton Fat Jade Porcelain, it's important to distinguish between the two different firing techniques: unglazed and glazed firing. Let's take a closer look at their differences.
Unglazed Firing of Mutton Fat Jade Porcelain:
Unglazed firing refers to the process of firing the porcelain body to white color at high temperatures without applying any glaze. Mutton Fat Jade Porcelain that is unglazed fired has a smooth and delicate surface texture, and a soft and gentle feel. A light blue hue can be seen through the porcelain, and the porcelain body's shape and texture are clearer, as there is no glaze layer to cover them.
Glazed Firing of Mutton Fat Jade Porcelain:
Glazed firing refers to the process of applying glaze to the surface of unglazed fired porcelain and firing it at high temperature again. Glazed fired Mutton Fat Jade Porcelain has a smoother surface texture due to the application of glaze, and is more durable than unglazed fired porcelain. The glaze layer also has an impact on the color of the porcelain, making the entire piece more colorful and layered.
How to Differentiate:
To Differentiate Between Unglazed and Glazed Firing of Mutton Fat Jade Porcelain, the Following Methods Can be used:
1. Observe the surface texture: The surface of unglazed fired porcelain is smooth and delicate, while glazed fired porcelain has a more glossy and shiny surface.
2. Observe the color layering: Unglazed fired porcelain has a relatively simple and single color, while glazed fired porcelain has more color layering and variations.
3. Observe the porcelain texture: The texture of unglazed fired porcelain is clearer, while glazed fired porcelain may have a slightly blurred texture.
4. Observe the translucency: Unglazed fired Mutton Fat Jade Porcelain has better translucency and may show a faint blue hue, while glazed fired porcelain has poorer translucency.
5. Observe the weight: Unglazed fired Mutton Fat Jade Porcelain is relatively heavier than glazed fired porcelain.
In conclusion, distinguishing between unglazed and glazed firing of Mutton Fat Jade Porcelain requires careful observation and comparison from different aspects. By doing so, we can better understand the production techniques and cultural values of Mutton Fat Jade Porcelain, and also evaluate its quality and value more accurately.
