When preserving with the Fowlers Vacola method, lids are placed on the bottle on top of the preserving ring and secured with a clip. When first put on the bottle, the lid appears convex, which will change to concave after processing, indicating the vacuum seal has formed.
Standard Lids are tin-plated with a lacquer coating, double-coated on the inside to food grade and single coated elsewhere.
Stainless Steel Lids provide a ‘longer life’ alternative and should be used for all high acid preserves, including pineapple and pickles.
