Hi John,
Nice Plate!
Just took a look at your roaster and was wondering if you'd considered
castable refractories for encasing the elements?  I've seen them used with
great success by kiln builders.  McMaster-Carr stocks them on catalog page
3320.  They're not cheap but home-brew formulae are readily available.  One
that might be worth trying :
2 parts Fire Clay
2 parts Grog (pulverized fired ceramics)
2 parts sawdust of various sizes
1/2 alumina hydrate
1/2 portland cement
enough water to allow you to form a self-supporting ball doesnt crack under
moderate pressure(too dry) or flatten by itself (too wet).  This formula
should be tamped into a mold.
  There are also soft refractory bricks that can be easily cut and/or gouged
by hand also available a pottery supplies.  AP Green is the manufacturer I
believe.
Nice piece of work by the way!

great tag John, I didn't know we were not allowed to attach pictures. I
guess I should read the list rule.

My sister in law just described them too me.  Thanks for the recipe.  At 
the moment, Mimi Newhouse (met her at the PNWG and is Mark Neuhausen's 
cousin) is seeing if porcelain would work for me.  I hope it will.

Thanks
