Overview
['The PZST16 is one of the larger cordierite stones in its price range, measuring 16.7 x 20.5 inches at just half an inch thick. That wide, thin profile covers more of a grill grate or oven rack than most competing stones under $60.', 'Cordierite handles thermal expansion without the cracking risk common in cheaper ceramic materials. The beige coloring is natural to the material and will darken with use, which is normal.', 'At $56.99 with a 4.3-star rating from 237 buyers, the PZST16 occupies a solid spot in the mid-range stone category. The review volume gives reasonable confidence in its real-world durability.']

Performance notes
At 16.7 x 20.5 inches and 0.5 inches thick, the PZST16 covers a substantial area on a grill grate. The slim profile means preheat time is shorter than a 0.75-inch stone, though it also releases heat slightly faster. Cordierite pulls moisture from pizza dough through its porous surface, producing the dry, crispy underside that distinguishes stone-cooked pizza. Preheat with the grill lid closed for at least 25 to 30 minutes before placing the pie.
What buyers say
The 4.3-star average across 237 reviews indicates a mostly positive experience. Buyers consistently mention the large surface as a key selling point. A handful report cracking, typically linked to thermal shock from improper cooling or washing while hot, which is a risk with any cordierite product.

Frequently asked questions
Is the Outspark PZST16 large enough for a 16-inch pizza?
Yes. At 16.7 inches on the short side and 20.5 inches on the long side, it can accommodate a 16-inch round pizza with room to spare on the edges. You could also fit two smaller personal-size pies side by side.
Can I use this stone on a charcoal grill?
Cordierite stones work on charcoal grills, but heat control requires more attention than with gas. Let the coals develop a white ash layer for even heat, then set the stone on the grate and close the lid to preheat. Avoid placing the stone directly over a fresh pile of flaming coals, which can cause uneven heating.
