I encountered some relatively cheap ceramic donuts at a farmers market - still they were more expensive than I thought they should be. Something like $20 a piece. Their purpose is to hold down the veggies or fruit while doing the crucial part of home canning (heating things up). There is a name for these things - forget now what it is - but when I googled it I found that most are not donuts but just simple shapes. Might have to get some if I encounter them again. I think they would look quite cool but something that handles vibration as well is probably better.
