Installation Maintenance and Best Practices
Step-by-Step Setup Guide
Setting up your Gotrays Cordierite-Mullite kiln shelves is straightforward. Start by cleaning the shelves to remove any dust or debris. Place them evenly on your kiln supports, making sure they sit flat without rocking. For best results, stack shelves with proper spacing to allow air and heat circulation.
Kiln Wash Application and Glaze Protection
Applying kiln wash helps protect your kiln shelves from glaze drips and firing residue. Here’s what to do:
- Clean shelf surface thoroughly before applying kiln wash.
- Use a brush or spray to apply an even, thin coat.
- Let the kiln wash dry completely before firing.
- Reapply kiln wash after several firings to maintain protection.
This practice keeps your shelves clean and prevents glaze from sticking, extending their life.
Troubleshooting Warp and Longevity
Cordierite-Mullite shelves are designed to resist warping, but a few tips help boost shelf lifespan:
- Avoid rapid temperature changes to reduce thermal shock risk.
- Load shelves evenly with balanced weight distribution.
- Don’t overload shelves with heavy or uneven loads.
- Inspect shelves regularly for cracks or chips and replace if damaged.
- Use appropriate kiln furniture and supports compatible with Cordierite kiln shelves.
By following these simple steps, your shelves will perform reliably, firing after firing.
