Masontops Pickle Pebble Glass Infinity Weights for Fermenting - Wide Mouth Mason Jar Pickling Weight Set
Masontops' Pickle Pebble Infinity glass weights for wide mouth mason jars, with a finger hole design for easy removal.
Weights hold the vegetables under brine, which is where fermentation goes right and mold does not. Between products the differences are real: glass discs versus ceramic stones, plain tops versus notched handles, and diameter tolerances that either fit your jar mouth or sit crooked in it. Some are heavy enough to hold a springy cabbage down, others ride up once gas builds. A weight that traps one leaf above the line defeats its purpose. We checked actual mass and diameter against common wide-mouth and regular-mouth jars, then looked at how easy each one is to lift out of a full jar with wet hands. Handles and finger notches matter more than they sound. Glass discs suit most quart and half gallon ferments; heavier ceramic stones earn their price in gallon jars and crocks, where a light disc simply floats off the vegetables.
