Overview
The Outspark PZST16 is a cordierite stone measuring 16.7 by 20.5 by 0.5 inches, built as a flat baking surface for pizza and bread on a grill or in an oven rather than as a standalone cooker.
Cordierite is the same ceramic material used in most dedicated pizza stones because it holds high heat evenly and tolerates thermal shock better than regular ceramic. At half an inch thick and beige in color, this stone is sized to sit on a grill grate or oven rack rather than serve as a complete cooking appliance.

Who it's for
Fits anyone using their grill or oven to bake pizza, flatbread or bread and wanting a stone that holds steady heat. Not the right pick for someone expecting a standalone cooker or grill, despite the outdoor cooker category listing.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cordierite holds even heat for crisp crusts
- Large 16.7 x 20.5 in surface fits full size pizzas
- Resists thermal shock better than standard ceramic
- Listed as an outdoor cooker but functions as a baking stone
- Half inch thickness means careful handling to avoid cracking
Performance notes
Cordierite absorbs and holds heat evenly across its surface, which helps produce a crisp crust by drawing moisture out of dough, and its resistance to thermal shock makes it more tolerant of the temperature swings common in outdoor grilling.
