Microwave Smelting?

Thanks, Platdigger!

After about an hour,

Using the hot spots they did it in 5 min to make brass from copper and zinc powder:

here once again the prepared crucible:

I don't see this as an alternative to any professional setup, ofcourse not. It's just for the fun of making this work.

Looks cool, wish I could read German. Just a taste of what you all must go through on an English site like this.
Are those flower pots with perhaps a graphite based cement in the second one.

No, they use common graphite spray, which has to be sprayed onto the refractory mortar inside the flower pot before each melt. The refractory mortar form has to fit exactly to the crucible.

Since Solar likes to post links written in German I have found that "Google Translate" is actually pretty good. You can copy/paste whole paragraphs and get an accurate translation with-in seconds.

for me google automatically asked if I wanted to translate --

thanks for the info on smelting --- I too just purchased one from an outfit in Canada --- gas or microwave ---

This works well for relatively clean precious metal powders. Using a graphite crucable, no flux is required. Takes me about 3 minutes to melt gold. I made mine myself using soft firebrick and silicon carbide powder + sodium silicate. The silicon carbude ring heats up as it absorbs the microwaves to around 1700*F. A graphite crucable is also important because it also absorbs microwaves and heats up beyond the melting point of the precious metal you are melting. Shortly after you have a nice metalic bead waiting for you.
