Does anyone know where I can get a few glass topped mason jars?

Walmarts has canning jars but I believe they're the metal top kind. Try ebay or maybe hit up some antique stores, most places can't even give them away unless they are of a rare color. Ball is still one of the biggest makers of mason jars maybe they still carry glass tops.

Target has them online http://www.target.com/p/bormio.....56249510050301008005

but think Henry is right, check out ebay or even craigslist. Good luck

They have some Presto glass top canning jars on sale on Ebay and a few other websites.

I will check ebay. Craigslist wants too much money for them. Thanks
