A Long History of Glass Making for Preserving Fresh Produce
The Kerr brand began in 1904, even though the company did not manufacture their own glass jars in their own factories until 1909. From 1909 to 1992, when the company was bought by Ball, Kerr continued to make all kinds of glass jars but became known for their fruit preserve jars. The company also later made ‘self-sealing’ jars and their most loved wide mouth varieties that even Ball copied.
Kerr Wide-Mouth Jars are Perfect for Canning and Preserving Natural Foods
Kerr’s canning jars were refined and developed over the years to be the best product that home cooks could use for their canning purposes. The jars are freezer-safe, phthalate-free and made in the USA. They’re perfect for all kinds of homemade treats and goods including salsas, syrups, sauces and fruit and vegetable preserves. But they can also be used creatively for gift giving, creative décor and for serving.
Easy to Use and BPA-Free Lids Means Easier Canning for At-Home Cooks
Kerr switched to BPA-free lids many years ago but also made another change that maybe many of their customers don’t know about – they’ve made it easier to use their glass jars for canning by eliminating the need for sterilizing the jars beforehand or for preheating the lids. The change was made in 1969 but still doesn’t seem to be widely known by most customers. This eliminates one of the steps of the canning process and makes it easier to preserve fresh produce at home.
