**Please note – 5.5″ Luna Glass Crock Weights are intended for fermenting vessels with an interior diameter of at least 6 inches**
Introducing Luna Glass Crock Weights! Stone Creek Trading developed these lead-free glass weights as an alternative to the traditional porous ceramic weights which are sold with most fermenting crocks. With traditional ceramic porous weights, the unglazed surface can absorb anything present in your ferment. When something goes wrong in the fermentation process, it can be absorbed into the porous stones. We’ve tried washing, boiling and setting them out in the sun, but it can be very difficult to clean the porous ceramic stones. As an alternative, glass is non porous and will not absorb anything! This means you never have to worry about transferring anything between batches.
The Luna Glass Crock Weights are a Stone Creek Trading exclusive item and patented. In addition to being non-porous, the Luna Glass Crock Weights are 10% heavier than the traditional porous ceramic weights. The added weight helps keep your ferment submerged where you want it!
The size of the Luna Glass Crock Weights indicates their diameter, or the dimension along the straight edge of an individual weight. We recommend ordering weights which are at least 1/2″ smaller than the interior diameter of your fermenting vessel. Luna Glass Crock Weights come in 4 sizes – 5.5″, 6.5″ (for a 5L Boleslawiec fermenting crock), 7.5″, and 8.5″ (for a 10L or 15L Boleslawiec fermenting crock).
These glass weights are individually handmade, which may result in a small variation in size. As pictured, you will receive a set of 2 weights.
These weights are a great way to upgrade your fermenting set up. No more worrying about using the same stones in different recipes or how to clean them!

Customers say
Customers find these glass weights fit perfectly in 5.5-inch crocks and work well in gallon-sized fermenting jars, appreciating their good weight and thick glass construction. They are easy to clean, with customers noting they can be washed and dried completely, and one customer mentions they keep fermenting vegetables submerged in brine. Customers describe them as beautiful and solid, though opinions on value for money are mixed, with some finding them worth the price while others consider them pricey.
