Best Luna Glass Jars

**Please note - 6.5" Luna Glass Crock Weights are intended for fermenting vessels with an interior diameter of at least 7 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 bacteria present in your ferment. When something goes wrong in the fermentation process, the bad bacteria or mold 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 sanitize 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 - bad bacteria, mold or smells and flavors. 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! Luna Glass Crock Weights are protected by US Patents D812,426 and 10,034,483 B2
