canning weight

Glass Pickle Pebbles for Mason jars are listed at roughly 2.1 inches in diameter by 1.1 inches high. Stoneware crock weights are specified by outside diameter to match crock sizes, with examples like 5-7/8", 8-1/2", and 9-1/2" depending on the crock.

The common materials are non-porous soda-lime glass for jar weights (Pickle Pebbles) and ceramic or stoneware for heavier crock weights.

Common units are grams, ounces and pounds; many scales also offer kilograms and milliliters (for liquids). Some models include specialized liquid units such as milliliters for milk.

Helpful features include a tare function to zero out containers, clear backlit or LCD displays for easy reading, non-slip feet for stability, and auto shut-off to save battery life.

Weights keep vegetables submerged below the brine, applying gentle pressure to maintain an oxygen-free environment. By preventing exposure to air they reduce the risk of mold and other spoilage.
