Overview

A rectangular cordierite pizza stone from Unicook measuring 15 x 12 x 0.53 inches in a beige, natural stone finish. Cordierite is the same thermal shock resistant ceramic used in most baking stones sold for ovens and grills.

Unicook's BP1512R follows the standard cordierite baking stone format: a flat rectangular slab meant to sit on a grill grate or oven rack and hold steady, even heat under a pizza crust. At just over half an inch thick, it carries enough mass to store heat through a baking session without cracking under normal temperature swings, which is the main reason cordierite gets chosen over ceramic or metal for this job.

Who it's for

Suits anyone baking pizza on a grill or in a home oven who wants a crisper crust than a metal pan produces. Less useful for someone who only occasionally bakes pizza and does not want to store a 15 x 12 inch stone.

Pros and cons

Pros
  • Cordierite holds even heat for crisp crusts
  • Rectangular shape fits standard grill grates
Cons
  • 0.53 in thick stone adds noticeable weight
  • Fixed 15 x 12 in size, not adjustable

Performance notes

Cordierite absorbs and holds heat evenly across the slab, which draws moisture out of pizza dough and helps the crust crisp rather than steam. The material also tolerates the rapid heat swings a grill produces better than ceramic, reducing the risk of cracking with normal use.
