[Clayart] best shelves for wood soda firing

[William Schran]

Maxine, Suggest you look at the different shelves available here:
https://kilnshelf.com/kiln-shelves/ I have worked with this company
for years and they are great in helping you purchase the right shelf
for your application. I might suggest you consider the Cryston TW
shelves. Make sure you are sitting down when you see the price! Rather
expensive up front but will last for many years!

Subject: [Clayart] best shelves for wood soda firing

Yikes just opened my Bruce Bower wood/soda kiln and all the shelves
had
 tipped. Fortunately I lost less pieces than I expected. It turns out
that
 one of the bottom cordierite shelves cracked & caused all the shelves
above
 it to slant.

 I am considering investing in silicon carbide shelves - I am
wondering if
 anyone has used these in wood firing. I looked online and there seem
to be
 3 types: conventional silicon carbide, nitrite bonded silicon carbide
and
 Advancer light shelves.

 If I do it, this is a big investment for me, so I do not want to make
a
 mistake. i would love the light shelves, because the kiln is fairly
small
 and it would give me more space for pots - but I fear the unevenness
of the
 flame might cause them to crack - especially if they were on the
bottom.
 The most shelves I would need are 6 half shelves. I wonder if I could
buy 2
 conventional silicon carbide shelves for the bottom, but use the
lighter
 type above them.

 I am wadding, but wonder if it is best that I coat the silicon
carbide
 shelves with kiln wash, in case I have ash drips - also the wood I am
 stoking the kiln with has soaked in a supersaturated solution of soda
ash
 and kiln wash for 4 or more days.

 Any advice would be greatly appreciated

 many thanks
 with blessings,
 Maxine
