Frequently Asked Questions

Kilner CZ891 500ml clip-top square jar FAQs

What is the Kilner CZ891 500ml clip-top square jar designed for?

The CZ891 jar holds 500ml, or 0.5 litres. It is a useful size for chutneys, pickled fruit, sauces and smaller quantities of dry ingredients such as rice, lentils, sugar or spices.

Its square shape uses shelf and cupboard space efficiently and lines up neatly when several jars are stored together.

Is the Kilner 500ml clip-top jar airtight?

The stainless steel clip applies tension to a durable rubber seal, creating a secure airtight closure when the rim and seal are clean and correctly seated. This makes the jar practical for pantry storage and suitable preserving methods.

Inspect the seal before each preserving use and replace it if it becomes cracked, stretched or damaged.

What is the Kilner CZ891 jar made from?

The jar is made from clear soda-lime glass with consistent wall thickness, an embossed Kilner logo, a high-grade stainless steel clip and a removable rubber seal. The glass is BPA-free and does not absorb odours, flavours or stains.

Because the contents remain visible, stock levels and food condition can be checked without opening the jar.

Can the Kilner clip-top square jar go in the dishwasher?

Yes, the glass jar is dishwasher safe. Remove the clip assembly and rubber seal if directed by the care instructions, and make sure every part is thoroughly clean and dry before reassembly or storage.

Regularly check the glass rim, body, clip and seal for damage, particularly before preserving food.

Can I pour boiling liquid straight into the Kilner CZ891 jar?

No. Do not pour boiling water or boiling food directly into the jar. Sudden temperature change can place glass under thermal stress and may cause it to crack or break.

Use the jar only with an appropriate preserving method and follow the preparation, heating and cooling guidance supplied with the product and recipe.

What are the dimensions of the 500ml square Kilner jar?

The jar measures approximately 125mm high x 115mm wide x 115mm deep. The compact square footprint is useful for shelves where round jars would leave more unused space between containers.

Allow a little extra room above the jar to raise and release the clip mechanism comfortably.

Is the Kilner CZ891 intended for repeated use?

Yes. The robust glass body and replaceable-style sealing components are designed around repeated filling and reuse rather than single-use storage. Glass also remains clear and resists retaining food smells or colours.

Long service life depends on careful handling, correct temperature practice and replacing worn seals rather than using damaged components.
