It’s not just Cleopatra that benefitted from a milk bath, your old china tea cup with a small crack in it can really benefit from being bathed in milk.

When dealing with vintage china small cracks are quite a normal discovery, buts instead of just waiting for the day that the small crack develops and inevitably breaks for good, try giving it a milk bath.

The idea is simple. You place your cracked piece in a heavy bottomed pan and cover it with full-fat milk. Next, warm over a very low heat for an hour. Allow the cracked china item to soak in the milk whilst it cools to cool. When the milk is cold remove the china item and rinse in clean water then remove and rinse.

As long as the crack wasn’t too far gone, it should now have resealed itself!

Top Tip

A slow cooker is great device to use for this technique if you don’t want to use a saucepan

How does it work?

The idea is that the protein in the milk expands when heated and fills in the cracks. It then bonds with the surfaces and as it cools bonding the china back together.
