Has anyone tried using melted wax in place of a lid? This is how my grandmother canned jellies. If this worked, then people could can in any sort of container.

I've not seen this tried for solar canning but I as well have family that use was for jellies, and it does indeed work. the preceding unsigned comment is by (talk • contribs) 03:16, 19 May 2007
I think it would only be safe for foods like jellies and jams since the seal is not very good. Wax contracts faster than glass as it cools and leaves a small gap around its circumference. Jams and jellies are dry and very high in sugar so only a few organisms, like mold, will grow. Walter Siegmund (talk) 03:42, 19 May 2007 (UTC)

Has this method been approved by the National Center for Home Food Preservation? I highly doubt it. And reusing spaghetti jars and expecting a good seal is certainly not recommended by anyone. Lemon juice to increase acid? no.

The quote about food spoiling from a lack of preservation methods is silly. Our concepts of preservation in the US are limited to freezing and refrigerating. The rest of the world salts, dehydrates, pickles, smokes, and ferments. We are one of the few societies that doesn't widely take direct action in our homes to preserve foods, until the power goes out. 15:56, October 17, 2012 (UTC)

This method is EXTREMELY unsafe in terms of keeping food from spoiling. Canning should only done according to the guidelines of National Center for Home Food Preservation's guidelines. 11:37, May 10, 2013 (UTC)
