The Hidden Reason Pizza Stones Crack After a Season Outdoors – And the Long-Lasting Fix to Ensure Artisanal Pizza Year after Year

Cooking a pizza in a pizza oven.

In my opinion, there is no better summer appliance than a pizza oven. But after months spent outside or in outdoor storage over winter, you might return to find the all-important pizza stone has cracked.

The culprit is often moisture, says pizza expert Vickie Hawley, founder of Delivita. Repeated exposure to fluctuating temperatures – especially during early spring use – allows moisture trapped in the stone to expand and contract, eventually causing it to crack and bringing this year’s pizza parties to a halt.

Fortunately, the fix is simple: A well-fitting cover that protects your best pizza oven year-round. Here’s how to keep your oven safe and ready for summer cooking.

One of the biggest pizza oven mistakes is assuming that, because many models are designed for outdoor use, it is fine to leave them exposed year-round or simply tuck them into outdoor storage. In reality, temperature fluctuations can quickly damage the stone – especially if you do not clean a pizza stone properly after its last use.

Vickie, founder of Delivita, explains, 'Pizza stones can crack due to thermal shock caused by rapid temperature changes and moisture exposure. If a hot pizza stone is left outside and temperatures suddenly drop, especially overnight, the combination of retained heat and moisture can weaken the material and lead to cracking.

'Moisture can also cause the stone to crack when reheated, as any trapped water expands under high temperatures.'

The trick is to find the perfect cover for your pizza oven, so that it seals tightly around the base to protect against harsh temperature fluctuations, she explains. A durable, weatherproof cover helps shield the oven from sudden temperature swings and keeps moisture out, protecting the stone and ensuring your oven is ready for use.

Beyond choosing the right cover, Vickie also stresses the importance of curing your stone after prolonged disuse, before the first use, and after cleaning a pizza oven.

'The curing process involves gradually increasing the oven's temperature using kindling and an eco firelighter, maintaining a steady temperature of 200-250°C (392-482°F) for four to five hours, and avoiding hardwood logs during this time,' she explains.

This slow, controlled heating process helps evaporate any residual moisture trapped in the stone, reducing the risk of cracks.
