Making Bricks
"Before standardisation, effectively-
totally free, yes, you made a brick having consulted with the works concerned
and looked at what they themselves wanted, they had probably got drawings
of bricks that they used, and if you wanted to get business out of them
you sort of said- well, we could do that and made them to the drawings
that the works provide."
"These were all pressed bricks and we had hydraulic
presses where you'd got a bse and then above it a platen as one would
call it- it could apply hydraulic pressure downwards, more sophisticated
presses had pressure applied from both sides...there was a lot of frictional
resistance at the side of the mould and therefore the pressure applied
to the top didn't always get to the bottom because of this frictional
thing, some of the pressure was taken by the side of the mould."
Brick Production
"Our bricks were lining the kiln they were sort of made with
tapers on them so that they- as you went round the circle they fitted
the circle. At that time initially they were made completely specially
for most individual cement works- the cement industry later on, standardised
a great deal...The bricks supplied to a given works was a constant width,
but not otherwise, it was only later after the standardisation that had
come in that most bricks were made to standard sizes, but some kilns wanted
a thicker lining, for example than other kilns, therefore in order to
be able to give a thicker lining you have to have a brick thicker in that
direction and tapered on the other sides."
