Making my own Nordic Gold please help

Rate this Entry
Hey guys I was looking at making a nice big bar of Nordic Gold. I will be sanding polishing & buffing the final product for my collection.
To make it Iíll need the following mix
89% Copper
5% Aluminium
5% Zinc
1% Tin
Iíll be using the following amounts below as Iím limited with my crucible size
2002 grams Copper
112.5 grams each Alum/Zinc
22.5 grams tin
My question is when mixing should I put all the metals in at the same time or melt from lowest to highest adding the next metal once molten or highest to lowest. I was a bit worried about adding Zinc and aluminium to molten copper as itís a massive difference in melting temps compared to the copper. Any help would be greatly appreciated . I will be doing a video on the whole process when I get some spare time and will upload the link and pictures once itís finished. I will be using my gas furnace with a graphite/clay crucible.
Thanks in advance for any help my friends.
