Corks for ceramics and pottery

Cork stoppers for ceramics and pottery

Tapered corks for thrown bottles, lidded pots, ginger jars and glazed vessels. Fired openings are rarely perfectly round, so a tapered cork is more forgiving than a rigid stopper.

Fired openings are never exact

Clay shrinks as it fires, and rarely evenly. Measure the finished piece rather than working from the thrown dimension, and measure across two axes — an opening that is 40mm one way may be 42mm the other.

A taper absorbs the difference

Because a tapered cork wedges rather than slots in, it accommodates an opening that is slightly out of round. That is why cork suits studio pottery better than a machined stopper.

Glaze changes the fit

A thick glaze inside the neck can take a millimetre or more off the opening. Measure after glazing, not before.

Common questions

If yours is not here, call 01895 717195 or email sales@just-cork.co.uk.

My opening is not perfectly round — will a cork still fit?

Usually yes. A tapered cork compresses as it is pushed in, so it takes up a small amount of ovality. Measure the narrowest axis and work from that.

Can I order corks in bulk for a production run?

Yes. Volume pricing applies automatically at checkout, and for regular orders we can hold stock of a particular size so it ships immediately.

Do you make corks to a specific size?

We do. If nothing in the standard range fits, we make bespoke sizes to order — useful when a run of pots all share the same opening.

Just Cork have a great range and I found exactly what I was looking for. Service was excellent with my parcel arriving quickly.
