This is Fiesta’s Stackable Mug in White — 16 ounces in the bright gloss-white glaze that anchors the Fiesta lineup. The Stackable is Fiesta’s larger-format mug; the body shape is designed to nest vertically into another Stackable, which saves real cabinet height when the mug shelf already runs tight.
It’s the morning-coffee mug for someone who measures the day in one full cup rather than two refills. White is the piece long-term Fiesta collectors start with — it pairs with every other color in the line, which is why most mixed Fiesta shelves end up half white. Dishwasher, microwave, and oven-safe to 500°F, with a handle sized for a comfortable grip even when the mug is full.
Fiesta has been making this dinnerware at its factory in Newell, West Virginia since 1936 — one of the longest-running domestic pottery operations in the country. Every piece is cast, fired, and glazed at that Newell plant, which is why the colors stay consistent from one collection to the next.
