Cracked jars are one of the most frustrating things in home canning. You’ve prepped, filled, and sealed… only to hear that dreaded clink as a jar breaks in the water bath. The good news? It’s easy to prevent with one smart technique: the Staggered Load Method.
Why Jars Crack
The most common cause is thermal shock: adding cool jars into boiling water or pulling hot jars into cold air. Glass expands and contracts quickly, and if the temperature change is too fast, jars break.
How to Use the Staggered Load Method
-
Stage Jars Properly
-
Always keep jars hot before filling (your oven at 200°F or simmering water works).
-
Fill jars one batch at a time and keep them on a towel to avoid cold counter shock.
-
-
Stagger Placement in the Canner
-
When adding filled jars to the boiling water bath, don’t put them all in at once.
-
Use your Hungry Artisan Jar Grabber to lower 2–3 jars at a time slowly into the canner, giving the water a moment to equalize.
-
Add the rest in stages until the canner is full.
-
-
Equalize Before Removing
-
Once processing is complete, turn off the heat and let jars rest in the hot water for 3–5 minutes before lifting them out.
-
Again, use the Jar Grabber and remove jars in small batches to avoid sudden temperature shifts.
-
Why This Works
-
Reduces thermal shock by allowing water temperature to stabilize
-
Keeps jars intact for better seal success
-
Saves time and ingredients that would otherwise be lost
