How to Load a Kiln (Without Losing Friends)
Loading a kiln is a bit like playing Tetris — only the blocks are fragile, handmade, and possibly still damp. Whether you’re firing bisque or glaze, a well-loaded kiln means better results and fewer heartbreaks.
Here’s how to do it properly — without cracking pots, melting shelves, or cursing under your breath.
1. Make Sure Everything’s Bone Dry
Seriously. Damp pots can explode in the kiln.
Let greenware sit for at least a week if thick or if the weather's been humid.
If in doubt, wait it out.
2. Plan Your Shelf Layout
Use kiln posts and shelves to create layers.
Leave enough space for heat circulation — about 2 cm above each piece.
Arrange similar heights together to maximise space and stability.
3. Stack Wisely (and Gently)
Place heavier, sturdier pots on the bottom.
Don’t stack glazed pots unless you’re using stilts or know what you’re doing.
Keep anything glazed at least 1 cm from the shelf edge or another pot.
4. Protect Your Kiln Furniture
Use kiln wash on shelves to protect from glaze drips.
Double-check for glaze on the pot bottoms — even a tiny drip can fuse.
A little paranoia here saves a lot of shelf-grinding later.
5. Load from the Centre Out
Start at the centre and work your way out evenly.
Balance weight side-to-side so your shelves don’t warp.
Don’t cram — remember, airflow = even firing.
6. Close with Care
Make sure nothing is touching the thermocouple or kiln wall.
Leave some space above the top shelf for airflow.
Double-check everything before shutting the lid.
Bonus Tip: Label Shelves
If you share a kiln, label each layer with a name tag or firing ticket. It keeps things clear and polite — and avoids “who put this here?!” moments.
