I still am not up to par after knee replacement....hurts a lot, takes =3D
forever to get over --at least for me, at this age--but all worth while.
However. As soon as I can "do" the stairs I get back to rewiring the =3D
big Knight kiln. Now some pieces of the brick came out, and I need to =3D
make some sort of shapeable mix to replace missing brick. =3D20
I know--i.e. remember--that there are simple mixes of either ground up =3D
soft brick, or clay/grog both with clay and something else to make a =3D
mortar. Is it sodium silicate? What is it?
Yes, I could look it up, but I would be grateful if someone would tell =3D
me. Exhaustion still dominates me right now.
All good wishes to all of you. Whatever you celebrate, celebrate it =3D
big, celebrate it holy. And all blessings for new year.

Be of good courage

You can cement broken firebrick pieces with kiln repair cement. That is
probably more practical than filling a large area with a cement and grog
mixture.
The key to successful firebrick repairs is to shape firebrick pieces so
they precisely fit into the damaged section. Use a small sanding block.
You can also cement broken sections back together.
Apply the kiln cement by dipping the firebrick repair piece into the
cement. This is much faster than applying cement to the firebrick with a
spatula, and speed is essential. Otherwise too much moisture in the
cement will absorb into the firebrick piece.
As you press the repair piece against the damaged firebrick section, try
to squeeze out the excessive cement from the repair joint. Wiggle and
twist the piece into place. This motion will not only squeeze out
excessive cement but will also press the cement into the firebrick pores
for a stronger repair.

I mitigate the absorption of moisture from the cement by doing a "slow dip"=
=3D
of the brick or patch piece into water=3D2C then towel pat excess surface =
we=3D
tness before dipping into cement. Dampen the receiving surface or cavity =
=3D
as well. The cement will stay fluid a bit longer and facilitate squeezing o=
=3D
ut excess cement and forcing cement into the brick pores as Howard says.
=3D20
Best to all=3D2C
