Hi all
I just wondered if anyone has had experience of using non-standard (of best product) clay pavers?
You can PM me if you like :;):

are you talking tegula style clays?
all clays are fired rather than cast so there is a tolerance when laying them
they should be checked for alignment every 4-5 courses
no need for a PM

Hi LLL
I was referring to 'seconds' or pavers which are not considered best quality.
Cheers!

Thanks LLL
Well I've been offered some clay pavers that are what I would call seconds. They are as I understand from the same batch as firsts - but have colour variation (reds when they should be completely blue) due to their position in the kiln as I understand? As such they aren't guaranteed against frost etc.
I'm assuming they won't have reached the correct temperature in the kiln - hence the colour differences? Also isn't this how they generate multi colour clay pavers anyway?
Perhaps someone could shed some light on the process - and if it would be too much of a risk to use them.
Pic below of an example - these should be completely blue.
Thanks!

well i have used Blenheim blues,which are completely blue,and Buckingham brindles,which look similar to what you have there
the fact that they dont want to guarantee them should worry you
it worries me
we used to buy regrades for footings,bricks that were either over or under fired in the kiln
normally the hottest part of the kiln produces darker colours and the cooler parts lighter hues
