Ball Mason Jars — Buy in Bulk & Save | Australia's Favourite Preserving Jars

Yes. Ball Mason Jars are specifically engineered for home preserving and are the most tested, trusted canning jar in the world. They are BPA-free, food-safe, and designed for use with Ball's two-piece lid system to create a reliable vacuum seal. Always follow tested Ball or USDA-approved preserving recipes for safe results.

Ball Mason Jars are available in a range of sizes to suit every recipe and storage need. Common sizes stocked at OzFarmer include 125ml (4oz), 250ml (half pint), 500ml (pint), and 1 litre (quart), available in both regular mouth and wide mouth options.

Regular mouth jars have a 70mm opening — ideal for liquids, jams, sauces, and runnier preserves. Wide mouth jars have an 86mm opening, making them better suited to whole fruits, large pickles, fermenting, and easier cleaning. Both sizes use Ball's two-piece lid and are equally safe for all preserving methods.

Yes. Ball Mason Jars are freezer safe. When freezing liquids, leave at least 2cm of headspace to allow for expansion. Use wide mouth jars for freezing where possible, as they are easier to fill and defrost. Avoid moving jars directly from freezer to a hot surface to prevent thermal shock.

Ball screw bands (the ring part of the lid) can be reused many times provided they are free from rust and dents. Ball flat lids (the disc that creates the seal) are designed for single use in preserving — always use a new flat lid for each batch of preserving to ensure a safe vacuum seal. Flat lids can be reused for dry storage where no vacuum seal is required.

Yes. All Ball Mason Jars sold at OzFarmer include Ball's two-piece lid system: a flat lid (disc) and a screw band (ring). Replacement lids and bands are also available separately in our store.

After processing, leave your jars to cool undisturbed for 12–24 hours. A properly sealed jar will have a concave (inward-dipped) flat lid and will not flex or "pop" when pressed in the centre. You can also remove the screw band and gently lift the jar by the flat lid — a sealed jar will hold firm. Any unsealed jars should be refrigerated and used within a few days.

Yes. Ball Mason Jars and screw bands are dishwasher safe. It is recommended to wash jars in the dishwasher or hot soapy water before first use and before each new preserving batch. Flat lids can also be washed in the dishwasher, but should always be inspected for damage before use.
