Kiln Furniture

Kiln furniture plays a crucial role in the ceramic firing process, providing support and protection to your pottery during the firing.

• Supports pottery during firing
• Prevents warping and deformation
• Ensures even heat distribution
• Protects kiln shelves from glaze drips
• Variety of types for specific purposes

Choosing the right kiln furniture for your projects is essential to achieving optimal results. Consider the size, shape, and type of your pottery, as well as the firing temperature and atmosphere.

Supports Pottery During Firing

One of the primary functions of kiln furniture is to provide support to your pottery during the firing process. This is especially important for larger or heavier pieces that may be prone to warping or deformation if not properly supported.

• Prevents sagging: Kiln furniture helps to prevent your pottery from sagging or collapsing under its own weight during firing. This is particularly important for pieces with delicate or thin walls.
• Maintains shape: Kiln furniture supports the shape of your pottery, preventing it from warping or becoming misshapen during the firing process.
• Reduces stress: By providing support, kiln furniture reduces the amount of stress on your pottery during firing, which can help to prevent cracking or breaking.
• Ensures even firing: Kiln furniture helps to ensure that your pottery is fired evenly by allowing air to circulate around all sides of the piece.

Choosing the right kiln furniture for your pottery is essential to achieving optimal results. Consider the size, shape, and weight of your pottery, as well as the firing temperature and atmosphere, when selecting kiln furniture.

Prevents Warping and Deformation

Another important function of kiln furniture is to prevent warping and deformation of your pottery during the firing process. Warping occurs when the pottery becomes distorted or misshapen, while deformation occurs when the pottery loses its original shape.

• Provides a stable base: Kiln furniture provides a stable base for your pottery to rest on during firing, which helps to prevent warping and deformation.
• Supports walls and structures: Kiln furniture can be used to support the walls and structures of your pottery, preventing them from collapsing or sagging during firing.
• Reduces thermal stress: Kiln furniture helps to reduce thermal stress on your pottery during firing, which can help to prevent cracking and deformation.
• Maintains shape: Kiln furniture helps to maintain the shape of your pottery during firing by providing support and preventing it from moving or shifting.

Choosing the right kiln furniture for your pottery is essential to achieving optimal results. Consider the size, shape, and weight of your pottery, as well as the firing temperature and atmosphere, when selecting kiln furniture.

Ensures Even Heat Distribution

Kiln furniture also plays a crucial role in ensuring even heat distribution throughout your pottery during the firing process. This is important because uneven heating can cause your pottery to crack or warp.

• Allows air to circulate: Kiln furniture allows air to circulate around all sides of your pottery, ensuring that it is heated evenly.
• Prevents hot spots: Kiln furniture helps to prevent hot spots from forming in your kiln, which can cause your pottery to overheat and crack.
• Reduces thermal shock: Kiln furniture helps to reduce thermal shock on your pottery, which can occur when the pottery is heated or cooled too quickly.
• Improves glaze consistency: Even heat distribution helps to ensure that the glaze on your pottery is applied evenly and consistently.

Choosing the right kiln furniture for your pottery is essential to achieving optimal results. Consider the size, shape, and weight of your pottery, as well as the firing temperature and atmosphere, when selecting kiln furniture.

Protects Kiln Shelves From Glaze Drips

• Providing a barrier between the pottery and the shelf: Glaze drips can damage the surface of the kiln shelf, but if you use kiln furniture, the glaze will drip onto the furniture instead.
• Distributing the weight of the pottery: Kiln furniture can help to distribute the weight of the pottery, which can prevent the shelf from bowing or breaking.
• Protecting the shelf from thermal shock: When the kiln heats up and cools down, the kiln shelf can experience thermal shock, which can cause it to crack. Kiln furniture can help to protect the shelf from thermal shock by insulating it from the direct heat of the kiln.

Variety of Types for Specific Purposes

• Shelves: Kiln shelves are used to support pottery during firing. They are typically made of refractory materials, such as alumina or zirconia, which can withstand high temperatures.
• Posts: Kiln posts are used to support shelves and to create space between the pottery and the kiln walls. They are typically made of the same materials as kiln shelves.
• Cones: Kiln cones are used to indicate the temperature inside the kiln. They are made of a ceramic material that melts at a specific temperature. As the kiln heats up, the cones will begin to bend and eventually collapse, indicating that the desired temperature has been reached.
• Furniture for specific types of pottery Kiln furniture is also available for specific types of pottery, such as tiles, beads, and mugs. This furniture is designed to support and protect the pottery during firing.
