[Stoves] Re: Improving longevity of steel stoves; Chiwicla-lining

[jason marshall]

Hilbertz has a reputation for being difficult to get ahold of.

I was a member of a group some years back that was interested in
growing seacrete.  I suspect his intentions overlapped theirs (and
given that bio, I'm now certain of it), and they never got a
satisfactory dialog going with him.

All I recall now is that a couple of the critical elements were 1)
having costal access for experimentation, 2) maintaining constant
current, not voltage, and 3) maintaining circulation even as the pores
begin to close. 4) lots of patience

If you want to build up any sort of a 3 dimensional structure, it may
be tricky preventing large voids from forming in the structure, since
it's going to grow outward from the wires, and the wires conduct much
more freely than the calcium does.  In all likelihood, you probably
have to build up a layer, shape it, and apply a second layer of wire
to the surface, lather rinse repeat.
