Tempering glass is expensive, but we think it's worth it. We have seen many glass fermentation weights that had air bubbles crack while in use.
These weights were designed to be the very best on the market for fermenting in wide mouth Mason jars. They are 68.5mm (2.7 inches) in diameter and 18.5mm (.73 inches) thick. They weigh 6 ounces each (170 grams).
The weights are cut from sheets of high quality tempered soda-lime glass. Mason jars themselves are made of untempered soda lime glass.
Most competing discs are not tempered, which is much cheaper to produce but less safe. Air bubbles and other imperfections in lower quality glass cause them to crack during use.
If you fill your jars up to the neck, one weight will perfectly cover your ferment. You can use 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. With more active ferments, you might not want to fill the jar into the neck to avoid overflowing brine. Then you will probably want to use two weights.
Glass does not leach anything into your food.
Dishwasher safe, boiling water safe, oven safe, microwave safe. Avoid sudden temperature changes.
International shipping is $5 extra to Canada and $10 extra everywhere else.

My husband loves to ferment things and we had a bumper crop of cucumbers this year. They came in time for our next batch. He really liked them.
My experience with Mason Jar Lifestyle has been "hands down" - exceptional. The products I ordered and received were of top quality and the customer service is exceptional. I give them a 5-Star vote to do business with!
I would love to try this product and I’m waiting for you to re-supply. When might this happen?
I bought these to weigh down my fermentations in Fido jars. The diameter is the perfect size; I can get my fingers in the jar to easily lift it out. They are nice and heavy. I do wish they were made in the US instead of China but the company states they do hand sand the edges. They are very nice and I would buy again.
I bought the fermenting lids & rings, and the weights. I love kimchi but it's a long drive from our home 'out in the boonies' to the nearest Oriental store so I started making kimchi at home about five years ago.
Most often my fermented foods were OK but not great -- because I wasn't keeping the leaves pressed down enough & fermentation was incomplete.
These glass weights fixed that issue right away! And the soft plastic valve tops kept the gas balance just right...both batches I've made since getting the items are at least 100% tastier than any I've made before.
