Our kitchen is fully tiled including windowsill etc.

Tiles are Pilkingon, a little under 200mm square and about 6mm thick.
They appear to be glazed gloss ceramic with an indented diamond pattern.

They appear to be obsolete.

No idea how they are fixed.

We want to make some changes to the kitchen. We need a few tiles for
areas that were not previously tiled but do not need at least 30 of the
tiles that are currently in place.

Anyone know if there is any chance of getting tiles off in one piece so
they can be re-used? Photo at:
