At Just Cork, we supply a wide range of natural cork stoppers and lids suitable for ceramic pots, handmade pottery, storage jars and decorative vessels.
Whether you’re an independent potter producing a small collection or an established ceramics business manufacturing larger quantities, we can help you find the right cork stopper or lid to complement your work.
Established in 2010, Just Cork supplies individual makers and businesses throughout the UK and worldwide.
Natural cork works particularly well with pottery and ceramics. Its warm colour, natural texture and understated appearance complement everything from traditional earthenware to contemporary stoneware and porcelain.

Cork is lightweight, renewable and naturally compressible, making it a practical choice for many ceramic containers.
No two handmade ceramic pieces are exactly alike, which is why finding the correct cork size is important.
At Just Cork, we stock 64 sizes of cork stoppers, from very small stoppers to larger sizes suitable for wide-necked containers.
Our corks are generally measured by top diameter × bottom diameter × length, helping you choose the best fit for your ceramic opening.
For tapered stoppers, the bottom diameter should normally be slightly smaller than the opening, allowing the cork to grip as it is inserted.

We understand that ceramic makers work at very different scales.
You may be a small studio producing a handful of handmade jars, or a commercial pottery requiring regular supplies of cork stoppers for an established product range. We welcome enquiries from both.
Just Cork supplies individual makers, small businesses and larger trade customers, with a wide range of stocked sizes and options for discussing more specialised requirements.

Cork is harvested from the bark of cork oak trees without cutting down the tree, making it an appealing material for makers looking to incorporate renewable natural materials into their products.
Its natural appearance complements handmade ceramics beautifully, while its compressibility helps accommodate small variations in container openings.
For products requiring an airtight, food-safe or liquid-tight seal, suitability should be checked for the particular container and application.
