Here is a copper bar I pour from the electric furnace.

Thank you! Great info...I appreciate it.

20 Mule Team strait out of the box...did not pre heat/treat it

Yes, I added borax to the liquified copper. It clean up real nice. I will post a pic when I get the bar cleaned up.

Ya. Just search "electric melting furnace" on ebay or Amazon and you will find it. Poured a nice copper bar last night.

It work great with the 3kg crucible. Thanks 

Here is the info 1400 watt 110 volt

First time doing copper. Watching videos and reading reviews, people had no problem doing copper with this furnace. I was just wondering if it was having trouble melting in the 1kg crucible since it is not as close to the heating element as the 3kg one. 

I just dont want to use the 3kg crucible if it is not going to melt.

Of coarse I waiting on a reply from the seller.

Thanks! So do you think the furnace is useless for copper? Or maybe magically it can would under the right condidtions?

Hi Everyone,

New here.

I recently purchased an electric melting furnace off ebay. It heats up to 1100 degrees C and I am still having trouble getting the copper to liquify.

It came with a 3 kg crucible and I also purchased a 1 kg crucible. Yesterday I loaded the 1 kg crucible up with copper, put it in the furnace. It slowly got up to temp 1100C and was red hot. After 1.5 hours it still would not melt...even though it was at 1100C.

I am not sure of other factors that could have effected the melt. 50 degrees F outside, low wind. I am not sure what the problem is. 

Is the 1 kg crucible not made for the 3 kg unit...it seemed a little loose fitting.

Ideas/thoughts. Anything will help.

Thanks
