Tempered Glass Fermentation Weights for Lacto Fermenting in Wide Mouth Mason, Ball, Canning Jars by Mason Jar Lifestyle (6 Pack)
Key features
- •6 Pack - Fits *Wide Mouth* (3" internal diameter) Mason Jars - Holds your ferment under the brine, leaving a tiny space around the edges to let out fermentation gasses. Glass does not leach anything into your food.
- •Highest Quality Glass - Tempered soda-lime glass is the same type Mason jars are made from. Most competing products are not tempered. Dishwasher safe.
- •Will Not Crack - Air bubbles in lower quality untempered glass can cause it to crack or break during fermentation. We found the sharp edges could chip, so we are sanding each weight by hand to round off the edges.
- •Big, Thick, and Heavy - 68.5mm (2.7 inches) in diameter and 18.5mm (.73 inches) thick. 6 ounces each (170 grams).
- •Use 1 or 2 Per Jar - If you fill your jars up to the neck, one weight will perfectly cover your ferment. For more active ferments, you will want to leave more head space and use 2 weights.

These are the PERFECT weights for my quart size mason jars!!
HoneyTiger✓ Verified Purchase•January 1, 2017
These are the PERFECT weights for my quart size mason jars!! They are heavy enough to keep my fermentables under the brine easily, and they fit every wide mouth jar that I own - a feat in itself compared to others I have tried. Do yourself (and your ferments) a favor and stop using brine-filled bags, stones, etc. and use these glass weights. They also sterilize beautifully in the dishwasher.
pretty tempered glass weights
Thor✓ Verified Purchase•September 15, 2016
The main reason why I purchased these was because they are made from tempered glass, unlike other sellers' glass weights, and there are no cracks nor bubbles due to this. I read other glass weights that were not made from tempered glass had cracks and bubbles in them. I use them only as weights to keep pickles submerged. I wouldn't recommend using them to press sauerkraut (use a wooden tool for that) or squeeze out bubbles, for fear of breaking/chipping/scratching the glass. The flat side is perfectly clear and the edge side is a clean opaque cut (no jagged edge). They look very pretty and do the job.
Nice quality but I find smaller veggies like chopped celery ...

Nice quality but I find smaller veggies like chopped celery will sneak pass this and float to the surface. Must. Learn. Strategic. Layering. I would buy again unless I figure out an alternative solution.
Agonized over alternatives, finally chose these. Glass cleans up the best!

Excellent shipping packaging. Almost zero chance of cracks or chips from shipping. I will probably plastic wrap these pucks up in groups of 3 or 4 for storage while not in use.
The edges look sharp in the photograph but are actually ground to a bevel (so they are NOT sharp and brittle). The weights are supposedly made of tempered glass (much, much stronger than artisan types of glass) so I don't expect these pucks to shatter, even if carelessly dropped occasionally.
These glass pucks aren't cheap, but they do a great job. No residual stains or unexpected cross-contamination of flavors and pigments or non-vegan ingredients for those who care about such things. Worth it.
I wish that they had a smaller hole in the center to make it easier to remove from a jar of ferment.

... of carrots and these glass weights worked so much better than using cabbage
cocii✓ Verified Purchase•March 24, 2016
I was a little worried they'd be too small and light weight - but just fermented 8 jars of carrots and these glass weights worked so much better than using cabbage!!!! Love this product. I ordered 12 of these so wouldn't be caught short....
