  • If I am not mistaken, the hand mixed heat resistant cement is called refractory. Great build! I thought when you hand made the lid / top and matching plug, it had to be initially fired (no metal to melt), then it was ready for use with metal. Did you make the crucible too? Thank you 🤓

    @j.lietka9406@j.lietka94068 ай бұрын

    • Thanks for the comment! The cement I used is fireproof. Quenching is not necessary, but I did it just in case. I didn't add reinforcing steel bars to the lid I made in the video, so it cracked after a few uses. So I rebuilt it after this with reinforcing steel bars. The crucible was bought from amazon. Please check out my other videos!

  • hello, to melt aluminum faster, can i use a steel crucible and with the wires more closer or attached to the crucible? which transmits temperature better, a sand crucible or a metal crucible?

    @muebledurable8270@muebledurable82707 ай бұрын

    • Thanks for the comment! My crucible is made of graphite. Both iron and graphite are conductors, so it is dangerous to put the wire too close to the crucible. If you want to melt faster, you may want to increase the power or improve the heat retention.

    • Hello! Thanks for watching! Welcome to the world of homemade metal melting! I live in a small residential area, so using a gas or other fire is a bit difficult, so I built an electric furnace. If your place is large and gas is easily available, I would prefer to make it with gas. I would also build a gas furnace if I could. I wish you success and enjoyment!

    @venuthandnalinroundtheworl8249@venuthandnalinroundtheworl824910 ай бұрын

    • Thanks for your comment! How many degrees you can reach depends on the amount of heat generated by the coils and the heat retention of the furnace. To reach 1800°C in a less powerful electric furnace, I think you would need to increase the thickness of the firebrick walls by about 3 times. I would also like to build a larger furnace to melt copper!

    • @@7chome_seisakusyo Assuming they are using nichrome resistance wire, which is what most furnaces use and what you appear to be using, you can't get to 1800C because nichrome melts at about 1400C. I'm not aware of any electrical resistance heating wire that can withstand 1800C. If I am in error please correct me as I would like to be wrong. It would be much better if the wire could get that hot. To get to those temperatures the options I know are: gas furnace, arc furnace and coal. Arc furnace is cleanest and easiest to build at home, but shock hazards must be accounted for.
