A while back (4 years ago) I was in the old Hayes gravel pit scraping up crushed stone for the foundation of my kiln and came upon a pile of decomposed iron red rock that was mostly dust so I saved it for when I started glazing later...

The throwing still is coming along but it seems I'm a lot slower than I usta be, maybe it just seems that way because this kiln needs twice and a half as many pots as the first Hobagama...

I think I might have discovered a materials mixup when I found a whole bucket of blond EPK I had stashed and forgot about. I think I took my kiln wash and some glaze EPK from a sack that had been mixed with fireclay and kyaite/mullite for lag but I read the bag and thought it was the clean EPK, although I felt it was looking different. I wonder what effect the fireclay will have on the kiln wash in the back half of the load if the alumina hydrate was increased. My guess is the mix has 25% or less of fireclay so it could be refractory enough to stand ^10 in the tail. Can't think which glazes I used it in but we will know when I fire eh? Oh well, guess I'll just have to leave it for now and make new wash for the front of the load and make new glazes with the clean EPK.
Later so stay in there eh!
