I have seen 4oz and 8oz muth jars. The ones from Dadant and from other companies, but I have yet to see a 1lb muth jar. I know they were manufactured at one time because I have one sitting in my kitchen on the counter. Does anybody know a site that sells these because I have been itching to get my hands on thse for a long time. And if not then could somebody please tell me the the site that sells the 4 and 8oz for the cheapest price. Thanks in Advance.
