"Not up to the task" star star_border star_border star_border star_border I bought two of these stones and both have shattered while backing pizzas. They were heated and cooled down as per instruction. The temperature of the oven was quite high, but not far over 220 and pizzas need a high heat to crisp up successfully. I will be claiming a refund, but I think it should be made clear that this really is not suitable for pizzas. Mrs Guerrier - 22 September 2021 support_agent A note from the team We understand that you followed the instructions with regards to not heating them up too quickly, but another reason this can happen is excessive moisture, perhaps from the pizza or from cleaning the stones. We're sorry that both the stones had cracked and we see we've now been able to help you with a refund.
