they are the best that has ever been made.
i would not want to be without my 15.
but, after seeing bob fritz' kiln totally destroyed...and
nils lou almost killed....and that kiln blown to bits...
i would rather scare a few, than be casual about
water and advancers.
bill is my shelf guru. i would take his advice on
anything related to shelves.
but, don't get your advancers wet...soak them or
wash them. stay out of damp places.
store as bill has suggested. on wood, in a dry place.
if you are concerned...do a slow bisque firing of them
in an electric kiln.
or, in your oven at home, if they fit.
just be careful...and you will love your shelves forever.

I just have to chime in on this and share my experience with Advancers. I ran a busy parks program in Portland OR. Just up the "hill" from Nils. I fired my advancers more than 300 times and never had an issue like this. I had a couple crack in the kiln during cooling but never any explosion. Here's where it gets interesting, I would regularly hose down the kiln yard to clean it,spraying water on the shelves. I would every week as I was loading the kiln spray water on my shelves with a spray bottle and than grind off any drips. I would load the shelves right into the kiln and start it within a couple of hours! I didnt know any better so I did what I thought was the right thing. Never did any shelve blow up. I had both Advancers in use and the slightly chaeper ones that I forget the name of. In my opinion those who have had this happen were firing thier kilns too fast. I would fire overnight starting at around 9:30 and come in in the morning around 7am and
start body reduction. So around 9 hours for the first 1700 degrees. I would than always let the kiln cool slowly and NEVER open the door until the kiln was below 400 degrees. I mentioned this to the Donna Turbos, the Advancers distributor an NCECA and she agreed that going too fast in either direction was probably the culprit in thes events. Just so you know.
