# Would An Oven Be Able To Catch Fire If Put On 400 Degrees For 20 Minutes

Will a block of wood burst into flames if placed in a 350 degree oven?

If you're talking farenheit, you might get smoke but you're not going to get flame. Paper has a flashpoint of 451 degrees Farenheit. For wood, it depends on the type of wood - it differs somewhat, but there are some general guidelines: typically you're going to need a temperature of at least 572 degrees F. (So if you mean 350 C, it's possible, depending on exact conditions). Oak, however, has an autoignition point of 900F (482C), so it wouldn't even come close. (Fuels and Chemicals - Auto Ignition Temperatures)Fire requires three things to occur: heat, oxygen, and a fuel source (Fire triangle). Actually, it also requires a chemical reaction to occur (fire tetrahedron), but that usually happens when you have the other three. Many people don't know this, but solid objects don't burn. Rather, they reach a state where outgassing of combustible compounds occurs, and it is these gaseous compounds that mix with oxygen and burn. This occurs practically in contact with the solid object, so it looks like the solid object is burning.You need this to start happening, which requires heat. You're supplying that. You also need the gasses to mix at the right ratio with oxygen. So, if you are able to get the wood hot enough it could start burning. Briefly. An oven is a closed space. Although it isn't airtight, there isn't really anywhere for the spent combustion gasses to go, and there isn't enough opening for enough oxygen to enter. So if you somehow managed to get the wood hot enough, it would most likely smoulder and smoke, but not actually ignite. At least, it's not likely as long as the oven is closed.But you should absolutely not test this yourself. It is incredibly dangerous:Once you have the wood hot enough, the oven will fill with combustible gasses. It won't burn, because the concentration of gasses is too high - there is not enough oxygen mixed in to allow combustion. But once you open that oven, the story changes. You have now introduced a source of oxygen to the mix of hot gasses, and they will almost instantly achieve flashover and explode. Look up videos of a backdraft if you want to see what could happen.I'm a volunteer firefighter - we discussed this sort of thing in a recent fire behavior training class. We didn't do the exact scenario discussed here, so I'm explaining based on theory from the class, but I can say with certainty that I would not try this experiment on my own, even with full gear and equipment standing by.

How long do you bake a chicken breast at 350 degrees?

How long it approximately takes to an oven to catch fire if there's no food in there?

How dirty is the oven? (Overflows, spillage, grease) Then it could take 30 minutes to hours depending on how much crud is in there. If it's clean, then theoretically never. My husband and I once had to leave the oven on all day, empty, to warm up the house while our furnace was being fixed.

Is it safe to put toothpicks in the oven?

Since you're putting your "clay" in the oven, I'm supposing you're using either polymer clay (which *must* be heated in an oven to harden) or one of the many air-dry clays (which *can* be put in an oven, but that would only be to speed up their natural drying).

Either one would be using a very low oven temp, and much lower than it would take to make wood burn in any way. So yes, you can put toothpicks in an oven on low heat as long as you don't place them near the oven coils or other places where the heat is much higher. (No soaking required for this use at this heat level.)

As for putting the toothpicks in your clay and baking that way, yes that again won't be a problem for burning, but air-dry clays shrink so that may affect the depth or position of the toothpicks (polymer clays with toothpicks inside, between, under, etc, are fine).

Can you use ceramic plates in an oven?

That depends on the plate. Most ceramic dinnerware plates can be placed in a cool oven and warmed slowly. Fine china or bone china should not be used in the oven. The thickness of the plate is also a factor. If the plate is thin and light, it could crack.Stoneware or earthenware plates should be fine as long as you proceed slowly and use them for warming and not cooking.

Can I put a cardboard pizza box in the oven?

Try it, I'm sure you will be able to. Don't lose hope!Just kidding.It all depends on the temperature of the oven!If it's off, then yes, without any hesitation. I wouldn't recommend keeping it in an even set over 200 degrees centigrade though. Cardboard burns at roughly 220 degrees centigrade, but this temperature again varies with the type of cardboard used,  the altitude of the location and so on and so forth.If you were putting the pizza box solely for the purpose of reheating the pizza, then there shouldn't be much of a problem. However, baking a pizza from scratch on a cardboard box would be foolish, of course, unless you wanted a cardboard flavoured pizza, along with a dash of fire.Enjoy the pizza btw! :D

Can leaving the oven on actually start a fire?

There is the risk of cooking unattended, which can lead to a fire. Cooking needs to be carefully watched. Perhaps a reason why most every microwave oven has a cook timer on it, so as to not cook the food for too long.There is also the risk that any high-powered appliance could have the potential to overheat and cause a fire. An electric clock that does not get warm at all, is a lot less likely to catch on fire, than a hair dryer, when those are left on unattended, well unless there is a short circuit or something.There is an added risk, that ovens were not designed to be a heat source for heating a cold home. I have heard of people having a fire, because they left the oven door open for too long, and the nearby wood cabinets overheated and caught on fire. When I use the oven, even though I am finished with the oven and have turned it off, I still close the oven door after taking the food out of the oven, and let it cool gradually, rather than leaving it open and having that blast of heat or risk of burning my hand.just a few internet images

Can you bake bacon in the oven without foil?

The oven is the only way I make bacon anymore.

No, you don't NEED foil but it sure makes clean-up easier.

If you don't have foil, I recommend using a glass Pyrex container like a lasagna pan. It will keep the fat from leaking out all over the oven.

If you make bacon this way, the easiest way to clean the pan after is to let it cool to room temperature, then put it in the refrigerator or freezer. Then you can just wipe out the fat with a paper towel.

I usually bake bacon at 400F for about 20 minutes or so. It depends a bit on the thickness/quality of the bacon.

Is it safe to bake chicken on wooden skewers in the oven?

to be on the safe side, i would soak the skewers in water for 30 min
