Ceramic Firing: High-temperature vs. Low-temperature

Just like molding or shaping greenware, ceramic firing also plays an important role in the production of ceramic products. Aimed at improving the quality, durability, and aesthetics, firing is considered to be a very important process in a professional daily-use ceramics factory like Jinhua and which focuses on the ceramic firing method in producing various kinds of ceramic products. We will discuss the difference between high-temperature and low-temperature firing and uncover their advantages and disadvantages to provide a more fundamental grasp of how ceramic products are produced.

The Overall Concept of Low-temperature and High-temperature Firing

The ceramic firing process involves transforming an unfired piece of clay into a durable ceramic by heating it in a kiln at elevated temperatures. In terms of the range of temperatures used, ceramic firing is divided into high-temperature firing and low-temperature firing.

• High-temperature firing: generally refers to the 1100°C to 1400°C firing. Fine porcelain, ceramic tableware and certain high-temperature resistant ceramic products can be fired at high temperatures.
• Low-temperature firing: The low-temperature firing is generally 800℃ to 1000℃. Low-temperature firing is generally used for manufacturing daily-use ceramic products such as ceramic flowerpots, and plain ceramic tableware.

Characteristics of High-temperature Ceramic Firing

• Hardness and durability: high-temperature firing can harden ceramic products and make them stronger and more durable against impacts. Such ceramic products are suitable for long-term applications, especially tableware, baking pans and other products that need to be subjected to high temperatures frequently.
• Texture and luster: Due to the heat effect when high-temperature firing is accomplished, a shiny glaze develops on the surface of the ceramic, with more texture and luster. This makes high-temperature fired ceramic products more sophisticated and meets the requirements of the luxury market.
• Resistance to pollution: high-temperature fired ceramics also have good resistance to staining because their surface is denser and so stains will be unable to enter it.

However high-temperature ceramic firing is a comparatively complex process, which requires more energy consumption and longer firing time, as well as higher production cost.

Characteristics of Low-temperature Ceramic Firing

• High production efficiency: low-temperature firing requires less time and energy, so the production efficiency is higher. Low-temperature firing is suitable for the production of large quantities, a single type of ceramic products.
• Color expression: Low-temperature fired ceramics can better express a wider range of colors and patterns, as glazes stand a better opportunity to integrate with the ceramic surface at lower temperatures and create rich color effects.
• Lower cost: Due to low energy usage by low-temperature firing, the production cost is relatively lower, hence beneficial for bulk production of daily-use ceramic products.

But the low-temperature firing of ceramic products is relatively low strength, prone to external force and cracking or breakage, for light and more decorative products, e.g., ceramic flowerpots, candle holders and similar.

High-temperature vs. Low-temperature Ceramic Firing Selection Criteria

When choosing the firing temperature, Jinhua selects high-temperature firing or low-temperature firing scientifically according to the usage needs and design requirements of the ceramic products. For example:

• For long-term use and high durability, ceramic baking trays and tableware, Jinhua applies high-temperature firing to ensure the durability and strength of the products.
• For its application in decorative ceramic products such as ceramic vases, candle holders, etc., JH uses low-fire to impart richer colors and patterns.
