a mug, named.
Hover or tap a label to learn what it does and why it matters.
The rim
The top edge.
The first thing your lip touches. A thin rim feels delicate and elegant; a thick rolled rim insulates the lip from heat and signals 'diner.' Rim shape changes how fast coffee hits your tongue.
FAQ
Mug anatomy questions
What are the parts of a coffee mug called?
The main parts are the rim (top edge), lip (drinking surface), body (the vessel), handle, foot (where it sits), and base (underside). Some mugs also have a thumb rest on the handle.
Why do espresso cups have thick walls?
Thick walls hold heat. Espresso is a small pour that cools fast in air, so a thick-walled demitasse keeps the shot warm and the crema intact long enough to drink it properly.
Does rim shape really matter?
Yes. A thin, flared rim spreads coffee across the tongue and feels delicate; a thick, rolled rim concentrates the liquid and signals 'diner mug.' Same coffee, different sip.
What's the foot of a mug?
The foot is the small ring on the underside the mug rests on. It keeps the hot base from touching the table directly and lets glaze pool cleanly without sticking to the kiln shelf.
