BCT are at least 40 years behind any other tile manufacturer, if they made cars they would still be churning out the likes of Austin Allegros etc. Size inaccuracies force a uncommon larger joint, glaze imperfections too common, material far too soft and vulnerable ( was the oven even switched on or just air dried, or are the coal miners still on strike). Stop stating they are ok for floors, you are simply lying, I would not use on a concrete or sand and cement floor let alone go anywhere near any kind of wooden subfloor. Glaze not to full edge of tiles, making it vulnerable to any kinda water penetration ie behind even a domestic sink let alone modern power showers, wall jets, waterfall heads etc
So come on BCT take the flared trousers, paisley shirt, kipper tie off and stop these crimes against tiling or Inspector Jack from the flying squad should be coming for you saying you’re nicked son!!!
