Confusing Information on using and caring for pizza stones.

I recently inherited 4 pizza stones of different sizes and configurations. Two flat, one deep dish and one rectangular with a lip. Went searching for instructions and here is what I came up with.

First off, always heat the stone with the oven. If you put a cool stone into a hot oven,
not only is there a chance that the stone will crack, but your food will cook unevenly.

Do not preheat stone.(Pampered Chef)

Because stone is unglazed and can absorb cooking oils, we recommend that you use your
stone only for baking pizza, breads and other "low-fat" baked items. Avoid recipes
calling for shortening (butter, lard or margarine) or oil. (Pfaltzgraff)

For best results, bake high-fat foods (e.g., refrigerated biscuits) or lightly brush
with cooking oil for the first several uses. (Pampered Chef)

Rub a generous amount of oil onto the cooking surface of the stone. Not so much that oil
is dripping of the edges. Place the stone in a hot oven and bake it until the oil has
been completely absorbed.

Prior to cooking pizzas on your stone, lightly oil the surface with olive oil. Do this
every time you use it, and your stone will take on a deep brown and golden tone with an
old world look. If you take care of your pizza stone it will last you a lifetime.

You can season a stone by spraying vegetable oil on it.

Aerosol nonstick spray is not recommended; it will create a sticky residue which is
difficult to clean. (Pampered Chef)

Generally speaking, pizza stones should not be treated with oil or nonstick spray.

How to use a pizza stone...Put the stone in the oven...crank the heat to maximum...and
come back in an hour!

Do not cook at temperatures exceeding 425 degrees Fahrenheit.
Clean the stones by placing them on the bottom rack of a 425 degrees Fahrenheit oven for
4 hours and scouring them, after cooling, with baking soda.

If consumers use oil on the stones and clean them using a 550 degrees Fahrenheit oven or
using the oven's self-cleaning cycle, as currently recommended in the instruction
booklets accompanying the stones, the stones can catch on fire.

Keep the pizza baking stone in the oven itself during the self cleaning cycle. It helps
to make the pizza stone cleaning process much easy.

To avoid a possible fire hazard we recommend you do not use any type of oil directly on
the stone and under no circumstances heat to higher than 475 degrees Fahrenheit. Do not
place in the self cleaning cycle of your oven as some self cleaning cycles heat rapidly
to over 700 degrees Fahrenheit and may cause the stone to break, a fire to result , or

  1. Without knowing exactly which baking stones you have, it's hard to say what you should do for each baking stone.

    With that said, regarding general use of and care for most natural baking stones, preheat your oven with the stone in it. To clean, simply wait until the stone is cool and scrape excess food from the stone using a paper towel, plastic or wooden scraper, or firm bristle brush. You can also clean them by leaving them in the oven and running the self-cleaning cycle then wiping off the carbon residue with a dry paper towel.

    Do not oil your stone or let excess fat drip onto it. Instead, use a dry "lubrication" method such as flour, cornmeal, or, my favorite, semolina.

    Do not wash your stone with water. As a matter of fact, properly cared for, you should never even have to get your stone wet (past a manufacturer's possible direction for an initial rinse and dry).

    You can leave your stone in your oven at all times, even when baking something else on another rack. However, if you think there will be spill-over, simply cover the stone with foil.

    It is actually a good idea to always leave your stone in the oven. It acts as a heat sink meaning it will work to even out your oven's temperature despite door openings. Also, many baked goods (pies especially) do very well when baked directly on the baking stone (again, preheated). With pie, the hot stone gives the bottom a big head start resulting in a pie with a bottom crust that is actually browned (instead of blond or soggy). With risen batters , the stone gives the batter a chance to start cooking and rising before the heat from the oven sets and crusts the top resulting in a higher, better risen product.

    This does not necessarily apply to proprietary composites or unusual baking stone materials (granite, etc.). You should find out what the manufacturer of each stone says regarding their particular stones in those cases.

    1. I got a nice chuckle out of those varying instructions. Mine would be leave it in the oven all the time, don't cook real buttery things on it and scrape off crud when necessary--though we regularly have our oven up to 500 for various reasons and the stone stays pretty darn clean.

      1. Really gives a person faith in manufacturers' instructions. For what it's worth, here's my experience...

        I've had a few rectangular flat pizza stones. One cracked spontaneously, apparently while cooling down. The others have lasted a long time (one died when I dropped it) and I don't baby them. The only concession I make is that if a stone is wet after being washed off (something I do rarely) and I'm going to use it the same day, I preheat it at about 200 degrees for a while before turning it up higher. Otherwise, I cook whatever I want on them and just scrape off any residue. I use them on my gas grill to make pizza (where they must get well over 500 degrees) and in my oven to make bread at 425 to 500 degrees, depending on type of bread. When I run my oven through its self-cleaning cycle I leave the stone in the oven and it does fine, producing the same fine ash on the surface as seen elsewhere in the oven. These are unglazed stones about 3/8" thick.

        1. Good information left here. "Pizza Stone" has become a generic name that covers many kinds of sizes, shapes and materials. One reply pointed that out, follow instructions included with any of the brand names and unless one wants potential problems, should get brick or ceramic stones that are of known materials; not to just find some flat stone and stick it in the oven. some kinds of stones will explode or crack. Even some commercially available stones have clear instructions regarding handling and cooling/heating procedures-and should be followed. I worked in restaurants which had coal/wood fired brick ovens some were well over 40yrs old probably older. Only ordinary care was taken, some bricks were cracked some areas had a real dark, mahogany patina. the center was mostly light colored where it must have been hottest and mostly pizzas were cooked. some oil splatter stains or burnt cheese marks. It was scraped with an ice breaker or scraper and swept with a push broom nightly. Modern ones can be allowed to cool down and more care can be taken; the coal and wood fired ones didnt ever really get too cool for days on end.
          At home, as another reply noted, it is a matter of choice and cooking habits. I leave mine in the oven all the time take it out to scrape off spillage when it happens and brush off the corn meal i use as pizza lubricant material. It is not necessary to wash my type, a commercially manufactured full oven sized 3/8" or 1/2" thick tile of the same material that would be laid inside a 'brick oven' style pizza stove. It is rated to be able to take heats over 1000°, i forget exactly since my oven only gets to about 600° maximum. I do not care about looks, I like how it preforms and allowed it to get that dark center area. does help my pies, quiche or as the other writer stated avoid the blond wet bottom crusts. for my pizzas, i may spend half hour or 45min to heat the stone, which i always bring up to temp with the oven, and my 17-18" pizza with the thinner type crust cooks in under 10, usually 8mins. i can only fit one at a time in. i cook directly on the stone, though have cooked on the aluminum pizza pans. I do not care for the deep dish type but would think this stone would be a superior way to cook them in the deep dish pans I have seen for sale.
          I never used any oven cleaner on the stone, but read there are some kinds which can clean it but the oils that have built up on mine over the years are inside the porous brick and have actually seasoned the stone to almost non stick. cheese does not stick to it, comes right off as do any sugary materials though that rarely happens it has and found this non stick benefit by accident. It will smoke rarely and not very much, but there is a distinct aroma when it is heating up and not unpleasant. I clean it with the metal dough scraper after it has cooled down for most drippings.

          1. First of all there are a lot of conflicting comments here.
            I have used the stone at 550 degrees & NEVER put oil on it.
            I always put it in when I turn the oven on, I don’t see a point of putting it in later. If you preheat the oven only that won’t do any good to get the pizza stone up to temperature. The stone needs to be in there 45-60 minutes for it to get to temperature. I would never remove the stone from the oven when still hot. Leave the oven open for ½ hour and then it should be easier to handle.
            I also use semolina for the ease of sliding the pizza onto the stone in the oven.
            I don’t see how anyone can say that oils make it non stick. Anything that is in the pizza stone such as oils will give off a smell and taste to anything that touches it. Cheese does not stick but the oils from it soak into the stone and is noticeable by the brown mark on the stone. So in thinking about it. Nothing sticks to the stone. Its porous and stuff gets absorbed in it. It is not a cast iron pan.
