Yes, your grandmother’s china might have crazing on it. Many vintage pieces do—including plenty of our beloved blue & white transferware pieces.
Crazing is the fine web of hairline cracks that can develop in the glaze over time, often as a result of age, moisture, and temperature fluctuations in how the pieces are stored. (Yet another reason to get the good china out of the basement and actually enjoy it!)
It doesn’t necessarily mean the piece was dropped, damaged, or structurally compromised. From a foot or two away, you’d probably never notice it.
So why should you care about crazing?
Because those tiny cracks in the glazed surface can trap food particles and bacteria, and in some cases may allow trace elements like lead—present in older glazes—to leach more easily. For that reason, we don’t recommend eating directly off plates with noticeable crazing or using them as everyday dinnerware.
But that definitely doesn’t mean they need to be retired.
In fact, once food is out of the equation, crazing is practically irrelevant to how you enjoy your pieces. Hang them on the wall. Turn a teacup into a candle or planter. Make a bird feeder for the garden. Give that gravy boat a new job holding lemons, soap, or whatever else you can dream up.
A little crazing doesn’t make a beautiful piece any less worth keeping—it just invites a new way to use it.
And if you still want to use a crazed piece for serving, simply create a barrier between the food and the surface—a doily, liner, or even another plate layered on top. A crazed dinner plate can also make a beautiful charger underneath a food-safe plate.
