Glazed and polished porcelain tiles

A. Hi cousin. I don't know whether you are still in high school doing a general technology science project, or whether you are an intern at a tile manufacturing plant and already know 10X as much about the subject as the rest of us :-)

If the former, I found:

-- it's very interesting, and it ought to tell you everything you need to know for your report.

If the latter, you need books which fully describe these technologies ... sorry, I'm not personally aware of any.

If you have some specific questions, a reader skilled in this subject may find your question and offer help ... but realistically nobody is going to spend hours explaining "in detail". Best of luck!

Regards,
