Video

Another stupid youtube video.

I'm only here because I am a kitchen installer and I have screwed into a door cavity haha

This is amazing. How does power consumption compare with other melting methods like the typical electric furnaces found on amazon? I have one of those electric furnaces and I think it takes about 1hr at 2kW to melt about 250g of copper so 8kWh/kg of copper could be the “standard” . Of course a lot of that energy goes into heating the chamber and crucible, which in your microwave is a lot less thermal mass and more efficient due to the low thermal conductivity of the blanket.

Hello , amazing video! can you use this to cook terracotta sculpture ? Many thank !

Does the smelted sand hold together well?

You are crazy in the best way! I'd be too nervous to do this stuff, but you make it look (almost) easy.

Excellent video dear friend, thank you !! Is it ok if i use that kind of kiln for ceramics? What temps could reach ?

Why not! All very creative!!

What did you mix the silicone carbide with to make the mold?

why is the iron not sparking, I thought iron lights on fire long before it's melted

Do you think there is a big difference between using something like "Polymaker PolyCast Filament" and PLA?

Oh step-diamond, im stuck

Very cutie, keep on there

very good

Im confused, was that writing on the printer “pursa mk4” stands for the toyota supra mk4 or its just a coincidence? 😅

Very cool

Wish I had seen your video before buying the wrong cable 😀

Love all of your videos! I'm currently making SiC molds based on your instructions. Any particular reason for making the benchy mold from SiC instead of plaster this time? Could you have remelted the cast iron within the SiC mold instead of breaking it open, to let it fill in the imperfections? Excellent content, you have a fan for life! Saludos desde Tejas :D

I definitely wouldn't mind seeing more stuff involving iron

Hi, what temperature do you reach when melting the cast iron? From what I can find, the melting temperature of cast iron (even in the low range with a lot of lead) is 1200C. What I don’t understand is how you reach temperatures above 900C based on your kiln design… If I get it right, your kiln works by microwaving the silica carbine lining. The microwaves should only be able to heat things that have a dipole moment (capable of dielectric heating; I.e are magnetic), but silica carbine has a Curie point at around 900C… So any microwaves above 900C should be affect the silica carbine anymore, and thus not be able to provide more heat anymore, which should mean the maximum temperature of your kiln is 900C. Or I’m missing something in its working principle. That’s why I’m so curious what temperature you reach!

Which blade/wire you are using to cut the copper?

I've discovered a quicker method to these results, first you go in a shop that sells glass containers, secondly you buy your required amount of containers and thirdly you save yourself a lot of time in making your own glass containers.

Like others have already commented: This is sheer genius.

He microwaved his copper? 😮

Go away please😢

as an Italian myself, i strongly disapprove this use of tomato and spaghetti. 😂

Great

I have also considered to use SiliconCarbide as a mold, but its rather expensive. Do you have a cheap source of SiliconCarbide ?

What was the reasoning for the wax? couldn't you put frozen pasta in the investment directly?

I wonder if using an ITC-100 HT wash either directly on the kaowool, or as another commenter recommended, a layer of refractory would decrease the melt time. It's one of the more common recommendations for gas forges to improve their efficiency. ITC-100 acts as an infrared reflector, so you don't loose to your insulation. It also has the added bonus of locking the ceramic fibers down, preventing them from going airborne. I'm not sure how it interacts with microwaves though.

You are a genius, your use of simple household tools to replicate complicated engineering processes is a thing of beauty.

Hello STF. I am trying to make a kiln of alumina and silica much like the ceramic insulation you used on this video. I found a patent on google that spoke about a mixture of "10-30% thermoplastic plastic or a resin organic binder with pure aluminum oxide powder at a temperature of 150-200 DEG C." The patent does mention PVA as a binder, but for a different slip method. Do you know of or have you succesfully used any binders to make pure alumina crucibles. Could sodium silicate potentially work? Thank you!

EXCELLENT advice THX so much

muttiiii TOP

Hello, how do i do ceramics in a crucible? Haha.

i've missed seeing your channel! looks like i have a lot of videos to catch up now 😀

Bravo......u only showed two ways......cheers

Wonderful ideas!!!😊

Aluminum ring at the price of a Gold one.

Not approved

Arte

which grit of SiC are you using for your crucibles ? I experience the crucible to become very soft when heating up the aluminium and i can hardly use it before the cruzible breaks down

The Italians are coming. Run!

Eeen Soviet Russia, glass cut YOU!

Well now I wanna see this done by gluing raw maceroni together or something, could make all sorts of shapes with a maceroni sculpture

Cook them less

Love the creativity, great job!! it takes talent to be able pull-off this one!! :D

Hi, can you use these crucibles in a kiln

Great video as always! I'd love to see more like this! This concept reminds me of NileRed's videos or mittensquad's video game challenges.

The skit lmao 🤣
