I was watching Corrie tonight and a scene showed a court building - it was an area that was built of white tile faced bricks. It got me thinking - at one time they were so common - used in Public Toilets, Schools, Railway and Tube Stations, Public Buildings, etc.
I can't think of any modern building material that is so robust or practical. They may not be fashionable now - but I wonder if they could still be cost effective - they are both structural and cosmetic, easy to clean, colour fast, robust, etc.
Does anyone know the time period when these were so heavily used?
Are they still made?
Did many manufacturers make them?
Etc.
