But why do some vintage mugs have concave bottoms? I'm sure just about anybody who has vintage mugs have noticed this. And vintage Mr. Bali Hai mugs have versions with both concave and flat bottoms. All of the modern mugs that I have seen have flat bottoms. Was this a manufacturing issue? Was it a way to allow restaurants to serve smaller portions? Perhaps to strengthen mugs for the constant slamming onto tables by hundreds of customers? They are a real pain in the neck to clean, particularly when one is found in the wild that 35 years worth of accumulated grime.
