Pickle Weights

Pickle Crocks have suddenly made an appearance in your average kitchenwares shop. I really like the ones with two separate lids, one to keep the contents under the brine, the other to create a water seal. It was actually fairly easy to make. But it then occured to me, why don't they sell just the weights? For use with an ordinary quart-sized glass Ball jar? So I threw about a dozen of these. If anyone would like to try one out, the small weight with the holes in it shown here, let me know and I'll send you one. I'd love to hear what people think of them. Ken
