Product Selection Differences for Kiln Furniture

When selecting kiln furniture, which includes shelves, supports, setters, and other items used for loading and firing ceramics in a kiln, several key factors should be considered to ensure optimal performance and longevity:

1. Material: Kiln furniture is commonly made from materials such as silicon carbide, cordierite, mullite, alumina, and zirconia. Each material has its own strengths and weaknesses in terms of thermal shock resistance, strength, and chemical inertness.

2. Thermal properties: Consider the thermal conductivity and expansion characteristics of the kiln furniture material to ensure compatibility with your firing process and the specific temperature ranges you will be working with.

3. Durability: Select kiln furniture that can withstand repeated thermal cycling, mechanical loading, and chemical exposure without warping, cracking, or failing prematurely.

4. Size and shape: Choose kiln furniture that is the right size and shape for your kiln and the products you will be firing. Adjustable or customizable options may offer greater flexibility.

5. Surface finish: The surface finish of kiln furniture can affect the way pieces move and are supported during firing. Smooth surfaces may be preferable for delicate items to prevent damage.

6. Cost: Consider the initial cost as well as the long-term value of the kiln furniture in terms of durability and performance to make an informed decision.

7. Supplier reputation: Select a reputable supplier known for high-quality kiln furniture and reliable customer service to ensure a smooth purchasing experience.

By carefully evaluating these factors, you can choose the right kiln furniture for your specific needs and optimize the firing process for your ceramic work.
