odd-sized canning jars

Asked September 24, 2013, 3:37 PM EDT

I have a number of 10 oz. canning jars with a 2-1/4" opening, the same as the "old" #63 canning lid size. Do you know where I could purchase lids for these jars? They were manufactured for MW Polar Foods, but Polar's website states they will not advise who manufactures their screw-on lids. These jars are considered either a 2 or a 4-screw type. I know #63 flats and rings can still be purchased via the Internet, but the #63 rings will not work. My husband suggested the possibility of using #63 flats, drilling a hole in a commercial lid (which does fit), and using the water canner to preserve jams and jellies. If possible, I'd like to avoid using wax.

The #63 lids and corresponding jars were used for home canning at one time, but are no longer recommended for that purpose. The jars and one-piece lids are still available for commercial food processing. The information I found about these jars and lids indicates that they are specifically manufactured as single-use jars with single-use, one-piece lids that were made for commercial canning. The suggestion of drilling a hole in a flat lid is not recommended. Use of wax for sealing jars of jelly is also not recommended. We can recommend only mason jars and two-piece lids (flat lids and screw bands) for home food preservation. Process jams and jellies in a boiling water bath for the recommended amount of time, according to the recipe.
