Johnsons were good clay but that was it imo think they buy a lot of tiles in nowdays

Not sure if you'd experience too much problem fixing brickbond on a tile of 360mm.
It's the glaze which can cause concern; faults, chips, bits missing, soft - are all to be found on these tiles and as they are now manufactured in the EU (Greece) we rest our case!
But unlike others I've never been a great fan of Cristal (H&R Johnson's - Johnson's) or any English tile.
Buy British - but only if it's of quality.
