If you measure flame temperature deduct 150C or more to get your metal temperature. Air is a bad conductor of heat and so is the crucible walls and that is why only 5% of the fuel heats up the metal the rest is wasted.
One trick to stop a crucible from sticking to the bottom of the furnace is to put a piece of cardboard under it. The cardboard will burn leaving a layer of carbon that won't stick
Do not be fooled - flame temp is always a lot higher than metal temp. Most dangerous and awkward pouring shank I have ever seen - overhung in two directions 😰 😱- you were clearly having trouble controlling the pour - throw it away and go to the industry standard of a simple hoop on the end of a stout (and straight) rod. Put about 20 thickness of newspaper on the plinth brick to stop the crucible sticking or even better 20 plus pages from a glossy women's magazine - it is weighted with kaolin (usually) and this, plus the paper ash, will stop sticking. Some say hat corrugated cardboard will do too. Bad gas may be a similar thing to what happens with copper it forms copper oxide and this reacts with dissolved hydrogen to give off steam on solidification, but this is only a guess...Martin
Could be Mn2O3 decomposing, happens at temperatures closer to 1000C. Also i think a reductive cover of the metal would be ideal as you melt it. Many people cast magnesium or aluminium alloy containing it by filling the top of the crucible with crushed carbon, sand type grain size. It should prevent a majority of the reaction with oxygen if you use like a cm or two of that.
I also didn't realize that the melting point of manganese is slightly higher than aluminum oxide. This is an incredible accomplishment, so congratulations on your success! *edit*--I see the melting point is just above 1,200 C, so it was a typo of 2,100 C in your video, but you stated the melting point at the correct temp later on.* It's still an accomplishment to be proud of, so I'm not removing my comment. Again, congrats!
Glad to see you with another video upload! I've been working on several in the background and I'm hoping to really grow my channel again with new uploads and hopefully new subs.
I’m really enjoying your videos very much I’ve been Creating videos for the last nine months on pouring copper and silver one of my subscribers has asked me to make something out of platinum do you think I could melt platinum was an Oxy set . Any advice would be very much appreciated thank you 🙏 😎👍
You should be able to melt platinum with an oxy set, a friend of mine uses an oxyhydrogen torch for platinum and the temperature is pretty similar. Small amounts (~5g) shouldn´t be a problem, anything larger might be a challenge.
Hi there. Love your work. I have a question regarding aluminum oxide. What chemicals or oxides can reduce aluminum oxide melting point if you heat them together in a crucible in a furnace? I know this auestion is not in par with the video above but I dont have your email address. I will appreciate your feedback
I'm about to make Cu-based alloy where the raw material is Cu (ingot), Manganese (powder form), and Aluminum (ingot). Do you think it is possible to cast? As there are two different type of raw material that I used. And if so, do I have to melt the Manganese first because it has the highest melting point?
The difficulty here is reaching high temperatures. Perhaps you should look at videos making a big electric furnace for more precise control of the melting process.
You can get it from dead alkaline batteries but it's a hassle opening them up. SomeAustrianGuy used another source for the metal though and they look like chips.
you are by far one of the most interesting channels on CZcams. cant wait to see what you do next! its also important to mention that I would be doing the exact same thing that you're doing if I had the tools, which makes this all the more better because I get to see you do the things that I want to do but cant.
Nice video and very cool furnace (or rather hot). You could use clear glass as flux and see if the manganese ions would colour it. en.wikipedia.org/wiki/Glass_coloring_and_color_marking I once melted some Magnesium which I thought was Aluminium. The resulting alloy of Magnesium and Aluminium is also very brittle.
The glass would just look like slag, I´ve made a lot of glass and you need a really small amount of manganese to see the purple colour. More than 0,5% Mn and you just get black. You´re right about the Magnalium, it´s about as brittle as my manganese ingot.
there is no free energy unless you somehow manage to disprove not just the entire field of thermodynamics but probably most of established physics as well. good luck with that.
Recovering energy would be difficult to do because the refractory ciment is a heat insulator. The only heat you could get is through the top hole and you need a connecting element that can resist high temperatures. I guess you could connect this further to a boiler in your house and collect some heat that way.
Guten Tag, Ich sehe mir ihre Videos seit einer Weile an weil ich meine ganzen Kupferdrähte die ich gesammelt habe einschmelzen möchte, nach langen Überlegungen mir für diese paar mal Kupfer einschmelzen und in Barren zu gießen, einen Ofen zu bauen erschien mir nicht weise. Darum dachte ich mir, ob sie mir das gegen eine Bezahlung abnehmen würden und mir aus meinem Kupfer, (ca 6 Kilo), 1 kg Barren erzeugen würden! Ich wäre ihnen sehr dankbar wenn sie darüber nachdenken würden. Noch einen schönen Tag.
My hat off to you SomeAustrianGuy. The temperature needed to melt the manganese metal is high. Congratulations for being the first on CZcams.
If you measure flame temperature deduct 150C or more to get your metal temperature. Air is a bad conductor of heat and so is the crucible walls and that is why only 5% of the fuel heats up the metal the rest is wasted.
You should melt bismuth next
Super erklärt und in einem hervorragenden Englisch. Große Klasse!

I've been using cardboard for many years and never had a crucible stick, good advice.
HE LIVES
The first video, where I see manganese metalic luster. :) Well done!
you should try preheating the air. much better efficiency at high temperatures.
I'm just here for the algorithm
very interesting as well as informative video as always. Thank you

When will came next video? Don't stop making video!

It is the boiling point at 2100°C... the melting point is 1246°C (see at 0:46 into the video)

Are you working on more synthetic ruby content? I´m looking forward to it!
@@SomeAustrianGuy I have some planned in the near future as well as making blue sapphire. :) I'm excited to get back to it.
hello I want to know if manganese steel can also be melted in cupola furnance.
Thanks for sharing

where did you get the manganese from ? also curious how much did it take to full all ingots?

if this was an active channel i would subscribe, but it's a dead channel you stopped making video's, why???????
