Crass Commercial Announcement

[morgaina]

I don't have a merchant's booth this Coronation.
However, I will have a small ammount of pottery for sale with me.
Please let me know when you are there if you have interest in anything.

(Just waiting for the kiln to finish firing, it's taking longer than I imagined it would, maybe because of the larger size)

This firing the pots were pre-bisqued.
Fuel kilns are definitely able to fire faster than electric, assuming the kiln design is efficient.
That being said 4-6 hrs. is firing too fast for me though. I like my glazes to develop slooooow.

I've noticed that some glazes do indeed require more time to express certain attributes. Rutile blues are one. Copper reds and purples also seem to develop better with longer firings (so long as I don't overfire and volatilize all the Cu). With others, like clear, temmoku, copper green and cobalt, it doesn't seem to matter--in fact, the ones I use are fireable down to cone 8. On the other hand, my propane bisques have been extremely uneven as far as heat distribution, especially the ones I do in the Veragama (I hook up my Venturi burner for this.). In this case, I might indeed need longer firings in the 6-8 hour range or longer to avoid pinholing.
