Setup, Compatibility & Care
Sterilization: Before filling, it is essential to sterilize these glass jam jars. You can do this by washing them thoroughly in hot, soapy water, then rinsing. Place them in a preheated oven at 140°C (285°F) for at least 15 minutes, or boil them in water for 10 minutes. Ensure the lids are also cleaned; typically, they can be submerged in boiling water for a few minutes (check specific lid material compatibility if unsure). Allow jars and lids to cool before filling.
Filling: Fill jars with your prepared preserves or other contents, leaving a small headspace at the top as recommended by your preservation recipe. Wipe the rim of the jar clean before applying the lid.
Sealing: Screw the lid on tightly to create an airtight seal. For best results, ensure the jar is warm when sealing.
Care: These jars are made of durable glass. They can be washed in a dishwasher (top rack recommended for lids if unsure). Handwashing with warm, soapy water is also effective. Avoid using abrasive cleaners or scouring pads that could scratch the glass. Inspect lids periodically for any signs of rust or damage that might compromise the seal.
