To guard the curve powerfully against this danger,
would it not be possible to case them on the
outside with a coarser kind of porcelain, such
as that of which the tiles called Dutch tiles are
made of? Q The difficulty would be to get them the casing
to stay on without being liable to crash by the
vicissitudes of temperature. If it were practicable
the best way would be to have them of the same length
with the iron so tubes they inclose: viz: at the
utmost 12 foot: or at least some very considerable
length. They Each length might be made in two pieces only
which which being semicylindrical would by
their junction compleat the tube. ⊞ To keep the
junction joint airtight these might be ⊞ The keeping the junction constantly air-tight might be a work of some difficulty, but I should hope not impracticable. Suppose it were by something of a
mutual insertion contained at the junction with
a hollow channel all the way down which might
be filled up with plaister of paris introduced in
a liquid state with an extra pin run through surrounding an iron pin which
it while get fluid for strength sake should
an addition be if deemed necessary, might be inserted for strength sake.

composed of, or cased over with, a sort of white porcelain
in appearance like the Dresden, in very
large pieces, if not all of a one piece.
