Question: Can you reuse canning jars?
Answer:
Canning jars may be reused, if they have been inspected and found to be in good condition.
Discard any jars with cracks or chips along the rim, since these have an increased likelihood of exploding during the canning process, and may not seal properly.
Also avoid using any jars over 10 years in age – they're fine for food storage, but not for canning.
