• 6 glass weights! Ships by 1-3 day Priority Mail. Our fermentation weights perfectly fit into a wide mouth Mason jar to hold your fermenting vegetables under the brine and press out any air pockets, leaving a tiny space around the edges to let out fermentation gasses. Glass does not leach anything into your food. Dishwasher safe.
• The weights are cut from sheets of high quality tempered soda-lime glass, the same material Mason jars themselves are made of. Most competing discs are not tempered, which is much cheaper to produce but less safe. Air bubbles and other imperfections in lower quality glass can cause it to crack, break, or chip. Many competing products are also too small and let bits of fermenting vegetables around them too easily, or too light.
• Big, thick, and heavy! They are 69mm (2.72 inches) in diameter and 12mm (.47 inches) thick. They weigh 110 grams (3.9 ounces).
• If you fill your jars up to the neck, one weight will perfectly cover your ferment. You can stack more than one weight if the jar isn't completely full or if you want to displace more brine to bring the level up to the neck of the jar. Because they have straight sides, these work best in wide mouth pint and pint & half jars.
• Your entire Mason Jar Lifestyle order ships for a flat $3, or free over $35 (you are almost there!). Check out our other products! Ships same or next day via USPS Priority Mail (1-3 days) from Denver, CO.

We experimented with different sizes and decided this is the ideal size. These just barely fit into the jar, but they are still easy to remove with clean fingers or a tongs. Be sure to also check out our all silicone fermentation lids for wide mouth Mason jars, now available on Amazon!
