Know before you buy
Yes. The combination of the rubber ring and the metal clamps creates a secure, airtight seal, making them excellent for preserving sourdough starters, dry goods, or fermented foods.
While the glass is durable and freezer-safe, it is best practice to let the jar reach room temperature before placing it in the microwave to avoid thermal shock.
The rubber rings are durable, but they will eventually wear out with repeated use and heat exposure. If you notice the seal becoming loose or the rubber cracking, it is time to replace them to maintain an airtight environment.
The jars are dishwasher safe, but for the best longevity, we recommend hand-washing the metal clamps to prevent potential rusting or discoloration over time. The glass jars themselves can go right into the dishwasher.
Yes, 28.7 oz is a generous size for a sourdough starter, providing plenty of room for the starter to double or triple in volume during fermentation without overflowing.
