How to use

Before first use, wash the jars in hot soapy water and rinse thoroughly. For canning, prepare jars and lids according to standard sterilization instructions: immerse jars in boiling water or place them in a hot oven as appropriate, and keep lids and sealing components sterilized. Fill jars with hot preserves while still warm, leaving recommended headspace for the recipe, then close using WECK lids and clips to form an airtight seal. After cooling, check seals and store jars in a cool, dark place. For everyday storage, clean jars after each use and inspect for chips or cracks before reuse.

Usage recommendations

Use heat-resistant handling tools when working with hot jars, avoid sudden thermal shocks (for example placing hot jars on cold surfaces), and replace any lids or seals that show wear. Do not use jars with visible damage. For best preservation results, follow tested canning recipes and safety guidelines for boiling-water or other processing methods.
