I am going to do my best to keep a kiln firing log.
My kiln is a 13amp plug in top loader called Little Chief. You may find this post useful if you are considering buying the same kiln.

- Stoneware glazes used:
- Buff stoneware clay from Commercial Clay
- VitraClay White Throwing Clay (2 smallest cups)
- Programme = Normal speed (mid) but with 20 min soak instead of 40 mins
- Max temperature went up to 1222°C during soak (for a short period time)
- Some unwanted bubbles on the brown tall vase but 20 min soak produced better result than firing #12 and #13
- Reactive White (inside) * Lagoon Blue (outside) on Buff clay is 👍 (4th photo)
- Rusty Mottle came out more like brown this time

- 1 tall vase, 1 small vase and 6 yunomis (1 kiln shelf)
- Tall vase had chipped foot ring due to glaze contacting kiln shelf
- Also glaze bubbled (brushed too thick or dust on the pot?)
- Be very careful when getting glaze off shelves!
- Programme = Slow more cautious stoneware firing
