I think I have found something useful on page 3:
Low melting karat gold brazing
Composition and properties of Au-Ag-Ge-Si- alloys. Especially the yellow alloy without Ge seems interesting to me, since the materials are at hand and those brazings are quite expensive to buy. So, I would like to find out, if this can be made without greater effort and equipment: Just start melting the (half)metal with the highest melting point, silicium, then adding the other metals? Voila, we have a brazing alloy for 1/10 of the normal price? Could it be so simple? ....I guess not, but I would be glad, if anyone can share his knowledge or even experience.
