King Arthur sourdough storage crock 1-Quart — glazed ceramic, non-reactive for starter care

King Arthur's Classic Sourdough Storage Crock is a 1‑quart ceramic container with a non‑reactive glaze designed to store and protect sourdough starter on the counter or in the refrigerator.

Keep your active sourdough starter organized and ready to bake with a purpose‑built crock that balances durability, safety, and everyday convenience. The King Arthur 1‑quart crock is made from glazed ceramic that resists reaction with acidic ferments, tolerates high temperatures, and offers an easy‑to‑clean surface. Sized to hold enough starter for multiple loaves, it works equally well for routine feedings, fridge storage, and short rises on the countertop.

How does this crock preserve sourdough starter quality?

The non‑reactive glaze prevents metallic taste transfer and shields starter from contaminants, while the ceramic walls moderate temperature shifts. Its 1‑quart usable capacity gives enough room for bubbling and expansion without overflowing.
