The clay that comes out of Mexico tends to have a lot more iron oxide which makes the pots a dark to tawny orange.
The clay is usually not fired to full mature temperature so the pots tend to chip or break a lot easier.
The clay from Italy and France is simply superb. I love the pink tones from France and the deeper orange tones from Imperata.
Usually the clay is fired to a full mature temperature so the pots are extremely durable, even in freezing temperature.
Terra cotta from America is as diverse as this country. Most of our commercial terra cotta comes from Kentucky and Tennessee and the factories fire the clay to full maturity making it durable.
One also sees a glaze applied over American made terra cotta. I don't know the reason for this but it strikes me as interesting.
Below is a photo of various terra cotta from around the world.
