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)

Holy moly! My June woodfiring was shorter than that! But then again, I had part of the roof collapse, which pretty much put the brakes on the whole thing, but I still had cone 10 down in front after 11 hours. I even fired my first oil drum kiln to cone 10 in 2 hours and I routinely fire my small Olympic updraft in 4-6 hours. Even the large gas kiln over at GFU fires in 9-19 hours and it's probably at least twice the size of yours. Although if you're single-firing, that may be different. Then again, almost all my experience with glaze firing has been in fuel-burning kilns. Still, I would expect something closer to 8 hours with a kiln that size.

I first read this as: "My June wedding was shorter than that, but then again I had part of the roof collapse....etc
Sounds like good times.

I think the slow culprit is my studio wiring, which was pieced together, needs re-wiring.

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.
