Years ago, I bought a small set of pottery dishes in Mexico which had a curious design. They were rimmed. The plate was divided in half by a ridge down the middle. One of the halves was further divided in half, such that it created three compartments: one half the plate size and two each a quarter of the plate size.

The dishes were hand painted in many bright colours (on reddish clay), which was their demise. It turned out that those darned things were decorated with lead-based paints and were useful for decoration (and slowly poisoning your enemies) but not for serving Mexican food to friends.

One supposes that glazing technology has improved since the seventies and that similar plates are available which are not toxic. One would like to find such plates by doing an Internet but the problem with Internet shopping for odd items is that one must know/guess the precise name under which the vendor lists the item sought. Which I don't, when it comes to these plates.

What, pray tell, is the name of a plate divided into one half compartment and two quarter compartments, in the Mexican fashion?
