3. Setup

Initial Cleaning:

1. Before first use, wash all jar components (glass jar, glass lid, rubber gasket, and metal clips) with warm, soapy water.
2. Rinse thoroughly and allow to air dry completely, or dry with a clean cloth.
3. Ensure rubber gaskets are free from any residue or damage.

4. Operating Instructions

Assembling the Airtight Seal:

1. Place the rubber gasket onto the rim of the glass jar.
2. Position the glass lid directly on top of the rubber gasket.
3. Secure the lid by attaching two metal clips to opposite sides of the jar, hooking them over the lid and under the rim of the jar. This creates a secure, airtight seal.

General Storage:

For general food storage (e.g., dry goods, leftovers, yogurt), you can use the jar with or without the airtight seal. For items requiring an airtight environment, use the rubber gasket and clips. For items needing air circulation (like sourdough starters), you may simply rest the glass lid on top without the gasket or clips.

Canning:

WECK 743 Mold Jars are suitable for both water bath canning and pressure canning. Ensure proper canning procedures are followed, including sterilizing jars and lids, and using new rubber gaskets for each canning cycle to ensure a reliable seal.

Sourdough Starter:

The wide mouth and straight sides of the WECK 743 jars make them ideal for sourdough starters, allowing for easy feeding, stirring, and monitoring of growth. For sourdough, it is often recommended to simply rest the glass lid on top without the rubber gasket or clips to allow for gas exchange.

5. Maintenance and Care

• Dishwasher Safe: All glass components (jar and lid) are dishwasher safe.
• Microwave Safe: The glass jars are microwave safe. Remove metal clips and rubber gaskets before microwaving.
• Freezer Safe: Jars can be used for freezing. Ensure contents have adequate headspace to prevent breakage due to expansion.
• Gaskets: Rubber gaskets are reusable for general storage but should be replaced for canning to ensure optimal seal integrity.
• Cleaning: The non-porous glass material resists absorbing odors or stains, making cleaning simple.

6. Troubleshooting

Common Questions:

• Scratches, Divots, or Swirls: Small imperfections are normal and do not affect the integrity or performance of the jars.
• Rubber Rings Stretching: Rubber rings are made of natural rubber. Contact with oil-based substances can cause them to stretch.
• Achieving an Airtight Seal: Process the canning jars with the glass lid, rubber ring, and metal clamps in a water bath.
• Avoiding Breakage: Avoid drastic temperature changes to prevent thermal shock. Keep the temperature difference under 122°F (50°C).
