Kilner Butter Crock

The Kilner Glass Butter Bell offers a traditional yet clever solution for keeping butter fresh and soft at room temperature. With a 200ml capacity, it’s perfect for storing standard-sized blocks of butter in a way that keeps them ready to spread—without refrigeration.

How it works:
Pack softened butter into the bell-shaped lid, press firmly to eliminate air pockets, and fill the base with 70ml of cold water. The water creates an airtight seal that keeps butter fresh for up to a week. Simply change the water every 2–3 days.

Key Features:

200ml capacity – ideal for standard butter blocks

Made from durable soda lime glass

No refrigeration needed – keeps butter fresh and spreadable

Airtight seal created by cold water barrier

Clear glass design with classic Kilner styling

Easy to use, clean, and refill

ORIGINAL AND THE BEST 
The glass jar is made from high quality sodalime glass material with pristine clarity and consistent wall thickness ensuring no weak points.

GLASS IS BEST AND SUSTAINABLE 
Glass is best for storing / preserving and transporting food and drink. It is made from natural ingredients so no harmful chemicals or toxins can leak into the food. Glass is BPA free and does not absorb odours, flavours or stains. Not only is glass a healthier option, it is made to last and never for single use. Kilner® continues to tackle plastic waste with our ethos of REUSE, REFILL, RECYCLE.

THE KILNER STORY 
The original Kilner Jar, invented by John Kilner and Co. in England is as much loved and successful now as it was over 180 years ago.
