Hello everyone, this is my first post, hope to be in the right section.
Thanks to all for all the informations you sharing, this forum is fantastic
I need some help with this..
I have some gold and silver ore..
I started milling the sized ore with an old corn mill (dry) and worked fine, what coming out was sand/powder grain. Then I screened the milled ore.
I wash it with water and dish detergent.
Then I take some and put in a graphite crucible with some borax and turn on the forge (mineral coal one, not gas)
The matrix is composed most of quartz, some altered pirite/iron(oxide), mica, gold, silver, very low ccopper.
This was my first melting experience, so I just give it a try to see what will happen
After 30 mins, I put off the crucible and the compost wasn't totally melted, but something happened. As in photo the mass is porous and hollow but it's quite heavy (32/33grams), it do not react with a mmagnet
For sure the melting must be done better with a properly flux, etc
But it reached high temperatures during "melting", a red stuff cristallized inside the melted ore mass, what is it???
Thanks to everyone for the help
