How do I keep my coffee hot longer, /diy/?

>>1053353
double-walled cups

>>1053361

Do they work as well as insulated mugs? I can't find a single result for an insulated mug that isn't for portable use.

>>1053353
get those thermo cups(maybe thier called insulated) and pre heat it with boiling water, usually while you wait for the coffee to Finnish.
get a lid for it, that insulate good and but some insulation on the bottom of it

>>1053353
Drink it, it'll stay 37 degrees!

>>1053368

I was thinking of insulating the sides of a ceramic mug, but I don't want to cover it. Having some kind of chargeable heated coffee mug would be really cool and the most ideal.

>>1053369

First wall copper, then insulation

While you're checking that out, have a look at Black Blood of the Earth. That guy does some interesting things.

>>1053353
Have you tried setting it on fire?

The lid is the most important bit. Test it out. 2 coffees in regular cups. put a saucer over one. wait 10 mins.

>>1053353
knit a scarf and make it wear it

why not just drink it faster..?

A thermos. Seriously, how is this a topic of debate?

>>1053370

Sure, if it's also easy to disassemble. Otherwise it will be the one mug you never bother to clean. Just get a thermos or a double walled cup.

increase the temperature of the room it is in

I agree. Someone should invent a way to keep my coffee hot in my favorite coffee mug.

>>1053353
Take the heating element out of a hot water heater, solder an appliance cord and on/off switch to it, immerse in coffee.

Profit!!!

2x styrofoam cups with a lid

>>1053353
Well its not diy but those vacuum insulated cups are popular lately.
Alternatively get some pipe, solder it shut so its airtight and put an hvac valve on it. Pull a vacuum and youve made your own vacuum sealed mug for roughly the same price as one at the store.
>but its yours so its better

>>1053797
This. Ceramic & metal mugs suck the heat out of the liquid inside of it. Using a styrofoam cup (especially with a lid) will hold the heat in the coffee.

>>1053376

I'll read about it later.

>>1053377

I have not.

>>1053407

I'll try covering it with something between sips and see if it helps.

Why?

>>1053650

Fair solution.

>>1053665
>Also: what's wrong with using a portable mug?

Most are too big and harder to clean. I would rather have a standard 10-ounce mug with a handle like in your picture.

>>1053666

I'll look it up.

>>1053676

Do you use one? I would like to know more about them.

>>1053695

That sounds complex and dangerous.

>>1053750

What is that made from?

>>1053797

I like the insulation of Styrofoam, but I would rather not drink out of it because of leeching. What if someone made a mug with Styrofoam inside of it? It seems like a cheap and effective way of making a more efficient coffee mug.

>>1053847

I'll read about vacuum insulated cups.

>>1053850

Basically, yes. Ceramic and metal has high thermal conductivity.

>>1053863

But I like California more.

>>1053867
>What is that made from?
It's a heating element. It could potentially boil the coffee and isn't the safest or smartest choice. Most of the answers in this thread are sarcastic, probably including that one.

The only other choice involving electricity is a plug in mug warmer. Batteries wouldn't work because you'd require a ton of current to power elements and keep a liquid hot. It would need a massive battery.

I'd also recommend looking into the vacuum cups. They're the most practical solution.

>>1053864
>Do you use one? I would like to know more about them.

Yes. It works great. I've had mine for years so it's not in those pics but they're pretty much all the same.
I bought several at the same time for less than five dollars each.

I use it a lot less now because I got a vacuum insulated cup with a sip lid for on-the-go use.
It works so well that I tend to use it at home too so I don't have to be near the warmer to keep the coffee hot.
If I worked a desk job I'd have a warmer on the desk for regular use.

>>1053867
>What is that made from?

It's an immersion heater. When plugged in, it MUST be covered in liquid.
If not, it will overheat and quickly burn out.
They're designed to boil water in a cup to make a hot drink.
(coffee, chocolate, soup, etc)
They are/were popular for travel use so you can make a cup of something hot anywhere you have water and electricity.
Not really handy for keeping coffee at a drinking temp because it has no switch and you need a place to put it after taking it out of the cup.
It will be hot and dripping liquid so a saucer works okay but you still have to unplug it each time.

Get a copper mule mug and a candle warmer

Easy fix

>>1053353

Getting enough plutonium might be problematic. It's much easier to just get americium from smoke detectors.

Around 100 million smoke detectors should have enough americium for keeping coffee warm.

>>1053867
>What is that made from?
It's a little heater element that runs off 120VAC. They used to sell them before faggots got all concerned about 'muh safety'. Fuck safety. Nothing else in the world will make your coffee taste as delicious as 120VAC at 60 cycles

>>1053963

I will look at both mug warmers and vacuum insulated cups.

>>1053992

Thank you for sharing your experience. I think I will try a mug warmer first.

>>1053993
>>1054092

Seems inconvenient.

>>1054009

I was thinking of some kind of tea candle powered heater might work, but it may be too hot and a heated plate seems much more convenient.

>>1054015

Seems dangerous.

>>1054020

Interesting.

>>1053867
Vacuum is literally best insulator.

>>1053353
run the cup under hot water for a min or 2 before filling. works pretty good to keep it hot for an extra 5 min or so

Do Americum-Coffee reactors have a negative or a positive void coefficient?
How good of a neutron moderator is coffee?

Just pour a handful of drain cleaner in you coffee anon, then neutralize the solution using vinegar or whatever before drinking.

If you're using a normal mug, fill it with hot water to warm it up, empty, then pour in your coffee.

>>1053353
Use phase change material. They have specialty wax blends that will solidify at a desired temperature and provide a shitload of heat while they do it (like ice cubes but backwards) . You want to encapsulate the wax in something because its probably not pleasant to drink wax with your coffee.

If your a buyfag they sell cups and metal "beans" with this shit in it.

Got your back

I like my Corita mug. Cork outside insulates way better than standard ceramic but doesn't keep it undrinkably scaldingly hot like a thermos.

Warmer plates ruin coffee and should be avoided, just keep it warm with an insulated cup for short term or vacuum insulated cup for long term.

Run your mug or cup under hot water until it heats up. Works for me every day.

you can use whiskey stones in reverse:

Or there's a bunch of the disposable instant heat ones, if those work for you: http://www.hot-can.com/USA/FAQ.html
they're a better choice for drive home coffee/lunch coffee, imo.

Accelerate coffee to close to the speed of light. Should stay warmer roughly 24x longer.

This always confused the fuck out of me. A well insulated mug would make these usb peices of retardation ineffective at best.

I say, that looks much more effective.

I always make a pot of tea, but never drink the whole thing before it gets cold, and microwave/otherwise reheated tea taste like garbage.

Microwave your coffee, Kek. Might as well drink bleach then..

>>1056519

Break open aa battery. Drop in coffee. Will be hot for hours.

>>1056381
>muh insulated cup

Reduce the surface area of the liquid, i.e, use a narrower cup.

Mugs, having a wide neck, allow the liquid to cool faster and the difference can be considerable because the vast majority of the heat is not lost through the cup walls but simply through the top. Reducing the surface area of the liquid will directly reduce the rate at which it cools.

"Coffee mug warmer" in Google's search box will help you my nigger.

>>1053353
Get a better mug. My coffee stays hot way too long because my mugs are THICC

also pour bigger cups, more coffee means more volume to lose heat. big things lose heat slower than little things. square cube etc

That will make your coffee taste like ass though. You don't want to add heat after It's made, just keep it from cooling.

Op: get yourself an old fashioned stainless steel vacuum bottle. Charge it with boiling water while making coffee. Pour small cups at a time. Problem solved. You can make the coffee at 5:30Am, and it'll still burn your lips when you have coffee after lunch.

1: Buy Glass-vacuum Insulated Flask/Bottle/Carafe
2: Buy Vacuum Insulated Stainless Steel Tumbler/Cup
3: Pre-heat interiors of both items using boiling water for 5 minutes.
4: Replace water with hot beverage of choice.

If you want cold stuff to stay cold, just pre-chill with ice water for 5 minutes instead.

Brand names don't matter so long as the flask/bottle/carafe is glass-lined and vacuum sealed and the tumbler/cup is stainless steel and vacuum insulated. The stainless steel-lined flask/bottle/carafe can actually flavor your beverage during storage, if you are okay with that then get one, they are usually cheaper.
