Fast Fire Glazes For the Tin Can Kiln:
OBS! These are just test-glazes for now, I will develop them further.
The Tin Can Kiln reaches 1000 – 1100 degrees Celsius. It starts from cold – to hot – to cold again in a maximum of 3 hours. Some glazes handle it, and some don’t, here I throw in some receipts to get an indication.
The short timespan gives some glazes problems with gas bobbles since they cool down quickly. In this kiln, every fire can have variations in the maximum temperature, so the glazes also need a broader temperature span.
So far Wash and thin-layer glazes work best since the clay doesn’t fuse together that easily.
All receipts are registered in volume!
