Review: Great pizza stone - We bake pizza every other weekend or so. And I’ve long been looking for the ideal pizza stone. This one is it. The size it amazing. Fits the entire oven. The weight and thickness hold the heat exceedingly well. I’ve got two of these now and I put one on each rack so I can bake four homemade pizzas at a time. Some tips; * Put the stone in before you heat the oven to 500-550 degrees. They need to heat up gradually and you need all that heat. * Preheat them for an hour. It does take that long to get them to retain all that heat exceedingly. * Don’t wash with soap. All you need to do is scrape them clean with a rubber or plastic scraper and then rinse with hot water. * Let it dry thoroughly before putting them away. Highly recommend.
Review: Great pizza stone - Great for my outdoor gas grill. Large enough to make a big pizza. I put it on the grill and let it come up to maximum temperature for the grill, about 600 degrees. Less than 9 minutes to get a great result. The pizza stone is thick and will retain the heat.

## Questions & Answers

**Q: Is this width exactly 20"?  We have a 27" wall over with a 20" wide rack.  I'd like to put this on lower rack but it only allows 19.75" item on top.**
A: Mine measures 20”X13.5”. You should always place a pizza stone on the lower or middle rack of your oven. If placed on the top rack the moisture from cooking will render your dough soggy, not crisp.

**Q: Can I cook things like biscuits, pigs in a blanket, and baked brie with puff pastry with the stone?**
A: Yes, but since you typically want the stone in the oven while it's preheating and you are assembling the biscuits or pigs in the blanket ahead of time it's probably easier to put on a baking sheet. However, you can certainly just put these directly on the stone. The puff pastry or other products that are oozing fats will discolor the stone, but shouldn't hurt it.

**Q: Can this stone be used over an open fire?  Thanks**
A: I would be cautious 
It requires a regulated temperature and I don’t believe that using it over an open flame such as a campfire or pit would no be able to regulate temperatures

**Q: can it be cut with a concrete saw?**
A: You could but why? You would expose the reinforcing fabric and who knows whats in that.

### ⭐⭐⭐⭐⭐ A must have
*by R***3 on June 22, 2025*

I use this for baking bread, rolls, to pizza. It is well made and performs great. Our bread and pizza come out with a crispy crust that tastes terrific. Simply put it in the oven with about one hour of preheating time. We then bake as usual. Simply try making your favorite bread or pizza with out it, then with it. The results are like night and day. This make a world of difference. It is also super easy to clean. We kept the original box for storing it which is also well made. If you love to make pizza and breads, this is a must have in my opinion. stars from us.
