How to Use Zinc Lids on Mason Jars

Zinc lids that fit canning jars can be identified by their one-piece style and the placement of the sealing ring. In modern, two-part lids, the sealing ring fits tightly on the top of the jar's rim; with zinc lids, the ring contacts the shoulder of the jar. Zinc lids should not be used for home-preserving, as the technology and materials have been greatly improved for safer canning.

Instructions

1. • 1

     Use zinc lids on jars for storing dry goods with a long shelf life like pastas, grains and cereals. They work well to keep out pests and keep this type of food fresh.

   • 2

     Clean the lid thoroughly to remove any dirt or oxidation before using it for consumables.

   • 3

     Place the lid over the rim of the jar mouth as with any screw-top lid. Tighten it with a clockwise twist, and loosen with a counterclockwise twist.
