There are a plethora of ways to think of terracotta & glazed brick.  Let’s start with the nomenclature. Is it terracotta in one word or terra cotta used as two words? Is this really Mexican tile that looks like adobe? Are we thinking of Italian red material? Well, both spellings are recognized as correct and as to origins, terracotta tiles can be Mexican, Italian, French, Catalan, Californian etc., etc. Loosely, we can translate the term as “baked earth” or “cooked earth”.
