Pectin is used in preserving fruits for jam and jelly making. This is used with paraffin wax to seal the tops of canned fruit and jelly.

Lime is not used in jam. Lime used to be used in pickles to make them crisp. However, the USDA no longer recommends using lime in food processing for home preserving.
Food is jammed by the act of preserving it into a "jam". These are made by boiling or simmering the food until it thickens or reduces to a syrup.
There are many retail stores that offer Preserving Jars, including ULINE, Ace Hardware, Target, Crate and Barrel, Kmart, Wal-Mart, Amazon, eBay, and Jam Jar Shop.
