Cast iron spreads heat evenly. If you but it on a stove the handle will get hot.

With that being say the "modern" cast iron pots have insolated handles

Cast iron's heat transfer is quite poor. It's about 1/5 of aluminum and 1/10 of copper. You can test this yourself if you have a laser thermometer. Heat the pan for a bit and then scan the pans surface with the thermometer. You'll see a fair amount of variation.

That would mean it wouldn't be suitable for cooking. Proper cast iron spread out heat very well, that why it is used.

I think people understand this property and rotate the pan to get an even hest distribution. Any case ... Could be wrong, but I looked up the heat transfer coefficient and its a fraction of copper and aluminum. On the other hand, it's really good at staying hot once it gets hot.

Here's a thorough answer on an engineering stack exchange.

/c/TenFoward: Your home-away-from-home for all things Star Trek!

Re-route power to the shields, emit a tachyon pulse through the deflector, and post all the nonsense you want. Within reason of course.

~ 1. No bigotry. This is a Star Trek community. Remember that diversity and coexistence are Star Trek values. Any post/comments that are racist, anti-LGBT, or generally "othering" of a group will result in removal/ban.

~ 2. Keep it civil. Disagreements will happen both on lore and preferences. That's okay! Just don't let it make you forget that the person you are talking to is also a person.

~ 3. Use spoiler tags. This applies to any episodes that have dropped within 3 months prior of your posting. After that it's free game.

~ 4. Keep it Trek related. This one is kind of a gimme but keep as on topic as possible.

~ 5. Keep posts to a limit. We all love Star Trek stuff but 3-4 posts in an hour is plenty enough.

~ 6. Try to not repost. Mistakes happen, we get it! But try to not repost anything from within the past 1-2 months.

~ 7. No General AI Art. Posts of simple AI art do not 'inspire jamaharon'

~ **8. Political commentary is allowed, but please keep discussions civil. Read here for our community's expectations.

Fun will now commence.
