Is This the Easiest Furnace Upgrade? How to Make Furnace/Forge Hotter.
Vložit
- čas přidán 17. 04. 2020
- Few moths ago I made a furmace from junk on my main channel "Odd Tinkering" ( • How I turned TRASH int... ). It was a very simple design and good for casting aluminum and other metals with low melting point. However I wanted to power it up so it can easily melt copper, brass and other common casting metals. I won't even try to melt iron this time because it will need some more upgrades, but making my own cast iron items would be really cool. Previously had never measured 1000 °C with the furnace and my previous attept at melting copper failed barely. This time I was able to get it to melt but it wasn't enough for proper casting the copepr would cool way too fast and it woudn't set to the bottom of my mold.
In order to make the furnace hotter I have 2 options. Make my burner more powerful or to reduce the loss of heat in the process. The higher the temperature difference between the furnace and the outside, teh faster it cools down. At some point the furnace reaches the point where the heat from the burner equals the heat loss of the forge. Then the temperature stops rising and once you shut the burner the temperature cools rapidly. I decided to try to a product I found. It is called ITC 100HT. On the internet I red peoples experiences and some said the y had got their forge even 200 °C hotter with it. The product is a ceramic coating that will reflect the heat back instead of letting it escape. The coating will also help to reduce damage to the fire wool making it last longer. Because the heat is reflected back it might also help to keep the furnace hotter if I have to open the lid.
A free way to support my channel is access amazon/ebay to do your regular shopping through these links. I will get a small fee from each product bought on amazon after clicking these links, whether it was the linked product or a different one.

Tools needed:
4:50 - Pinkie out? You classy.
7:12 - oh, no, you just odd.
You can preheat your molds to ensure no moisture is present when pouring. This is likely what caused your mini explosion.
Yes it was actually snowing a bit when I started but it had stopped at that point but probably a flake or two had landed on the mold which caused that
when in doubt pinky out!
Haha
I don't know why but I expected a sip from the cup
Always heat your Mold before pouring the liquid copper not to get any surprise by splashing. And take on safer shoes. Yours will burn very fast & well...
I love this furnace. Please upload more often of stuff now that we are all quarantine.
Thanks! I will see what I can do. Last week there was no video because of a failure but I can't do more than 1 video per week and sometimes even that fails. It's a lot of work to get everything done
Put a couple thin fire bricks in there surrounding the crucible and it will work even better.
Very creative! Never stop building👍👍
Thanks! I won't!
Hey odd experiments, I think that if you watch some videos of “bigstackD casting” your skills about casting will increase because he’s melting aluminum and copper
if you are considering building a new forge i would suggest having a look at Alec steele's videos on building forges as they are very in depth and fun to watch.
I know if I were to touch the glowing hot furnace equipment I'd lose my hand, but the light just makes me wanna touch
Good to see how well it worked. I would treat your Koawool with rigidizer though for your safety and also to stop bits flaking off. Kaowool once in the lungs stays there forever.
what type of wool is that as if its k-wool then the main concern is that the individual fibres are small enough to penetrate deep into the lungs and possibly lead to the development of lung cancer
I made one from a beer keg, with a single torch and it had no problem melting an entire 3kg copper statue and keeping liquid enough for pouring
Very interesting video. Also, to help with unmolding, you might want to spray a light coating of graphite in before you pour.
Towards the end I was thinking, "wow I really like how it glows". Then you say the same thing lol.
Looks like Mordor 🙂 awesome video!
My thoughts also
Please continue doing videos, I love this! Could you do a video explaining the parts of a gameboy or something like that? It's just an idea I will watch whatever you do! ❤
Great video as always :) Hopefully now we'll see the furnace more in action for Tinkering videos? :D
If I have projects where I need it. I will post new video where I use it in few hours but I will only heat an item rather than melt or even get it red hot
I think you should angle the inlet so it swirls around the crucible, rather than hitting it straight on and then heading straight out the top.
It actually is an slight angle and it swirls around but maybe it could have been even more like that
I know I’m late, but The King Of Random, has a few videos on making Foundries. I made one with my dad a few years ago, based off Grant’s original design and it was easily able to melt copper!😅
This is kinda a guess but the reason it stuck to the mold is probably because there was a small amount of water in there which is why it did a splatter when pouring but I could be wrong keep up the awesome videos
Now that you mention it, I think there was a tine bit of snowing before I did the pour so that is definitely possible.
Odd Experiments glad I could help!
12:00 we got a restoration video in this one too!!
I think one big issue is the size of your forge, it's got a lot of volume, and so it'll be a lot harder for the one torch to heat everything up to snuff. Unless you really need a big crucible, you shouldn't use one.
Awesome you should make more videos here!!! keep it up :D
Love the Video!
...but i am slightly concerned about the lack of protective gear, I was sure you would get a hole in your foot in your canvas sneakers. Stay safe out there:-D
Btw, what do your neighbours say about a lit furnace in the backyard at night ;-) you set the mood for the whole neighbourhood
Yes I had to stop at that point because it was late and it is kind of loud
I was wondering if instead of painting the ceramic coating onto the wool, could you make a tubular liner to fit inside and coat the smooth interior of the liner? Would steel work as a liner under the coating?
I almost watched all episodes on your two CZcams channels , I learned a lot beside too much fun to watch , but please keep the information subtitle little bit more longer 10 sec , thanks
you have to bend the flame insertion .. so that a vortex is created inside, to increase the heat
Thanks for the foundry knowledge hookup and the link. You rock 🪨 🎸 💪
some improvements you can try :
- give an angle to the torch income to create a whirlpool in the furnace, the flow of heat will stay longer inside
- make an inside wall of heat refractory and heat resistant stuff, the mix of "ceramic" is too thin
Quickest restore on the channel, the mold :D
Looking at the ingot you made, it looks like there's a few tiny dents in it. Maybe the mould wasn't completely smooth, and the copper got stuck on a tiny indent. Or the coating on the metal did something to make it stick or something like that.
Anyway, nice video! Reminds me of the old King of Random forge videos.
I'm guessing it might be the coating as I have not used that pan many times yet.
This is cool
Thanks April! It was a lot of fun and interesting to see if such thin coating of what essentially looks like clay can actually work
@@Odd_Experiments Your welcome 😁!
The ceramic paste looks like homemade chocolate ice :D
Было интересно! It was interesting!
could you make a tutorial on how to clean a computer monitor?
I've watched a few videos on making a furnace. Almost all of them use a powdered coating called "Satanite." Might want to look into that. I believe I is more of a paste than what you were using
Hope you didn't spend too much on that high-temp coating. $0.20 of clay + others would have achieved the same thing. Also, try spraying the 1st coat next time - might have been a little tricky in the tight space, but easier. Also, use a drill attachment to mix the coating, unless you like squishing it in your hand.
My lungs burn just watching the first 10 seconds. Cover that wool.
Looks like now you have to repair the steel mold hehe
How does the wool not burn?
You should check the bigstacked channel for big improvement... nice one anyway 😄
maybe one of these days you should get yourself one of those permanent furnaces for stuff like forging and blacksmithing lol
Liquid ice 🤣🤣. You almost got me...
When next experiment
You forgot the chocolate chips! :D.
have you try to use another gas like hydrogen, i know it is a bit dangerous but is very hot 🔥
30k subs with 3 videos challenge
Actually he passed
Wolo = we only live once 😅
Your furnace is huge compared to the crucible. Make a smaller furnace and you will be able to get it hotter. Also, copper is hard to cast, use bronze (copper and tin)
Get a Devil-Forge!
u suppose to use a refractory first then put itc 100 on it
7:12 😂
you forgot to spray pam
Can I please have one of the game boy's you restored on your other channel please please and what is liquid ice
Liquid ice is just what you think it is 😂 the liquid form of ice, water
it is wet not vet check it at 5:45
You need to upgrade your mold to cast iron
1 cup 1 guy
King of random?
Why didn't you just empty all of it into a bigger tub and use the tub it came in to measure out the water it would have saved you a whole lot of hassle lol still it was a cool video
I didn't know if I will need all of it. If I needed only half of it I could then use the other half later for something. That tiny bucket costs something like $60. You will save that sum in gas etc pretty fast but still I don't want to waste half of it
@@Odd_Experiments I see your point
fire wool is dangerous for health!
like 1000
Steal mold = muffin tin. 🤣🤫
But it's steel. There are also aluminum ones which would have just melted away
I never doubted you... just pointing out all the different uses for a muffin tin😀
@@Odd_Experiments Should have greased it first 🤣
3:56 🤣 you joke
