Placing 1 mL of Au chloride and 1 mL of platinum chloride on top of fluxes, which equals 1 mg of gold and 1 mg of Platinum.

12x --  the silver bead that is being inserted (inquarted) into the fluxes which measures = 0.054”

The melted fluxes containing the Ag, Au & Pt.

The broken crucible showing fluxes and the collection of an odd looking AuPt button, which = 40 grams.
The fluxes remained the same and the heat of fusion was as close to previous assays as possible, yet this big discrepancy on the weight of the Lead Button.
Clearly the Lead button is very brittle because it broke in to with the crucible.

This portion of the Au & Pt Lead button is very crystalline and I have no understanding as to why. It is a known reality, which I have seen many many times that even small amounts of the pgms can cause significant physical characteristics of the Lead Button and more so the silver prill.
Resting on top of the Lead Button is some attached slag and at bottom is the attached piece of the crucible.

10x – this magnification somewhat shows the crystalline form of the Pb, Ag, Pt and Au metal combination. Higher magnification does not provide a better image.

The cleaned Au & Pt button in a bone ash cupel.

10x – The AuPtAg prill still in the cupel.
The size of bead =  0.055” -- whereas the original Ag inquart size was 0.054” so some Ag or not all of the gold and Pt was recovered.
This golden colored prill is definitely a different crystalline surface texture than any silver bead. Again, more or less Pt most likely would cause a major surface appearance.

20x – A magnified view of the AuPtAg bead still in cupel

30x – A magnified view of same AuPtAg bead still in cupel, but showing a little more of the crystalline surface structure.

20x – The AuPtAg prill now on glass slide, in 1 drop of nitric (70%) acid and 2 drops of distilled water.
It did not take long for the blacks to begin forming as the silver began dissolving with a little heat. The golden coloration of the surface has become more silvery.

30x – The AuPtAg prill showing at higher magnification of the surface crystalline grain boundaries.

10x – The Ag has dissolved leaving the Au & Pt as bunches of blacks that have no definable crystalline structure that I could see even at 100x.

20x – A higher magnification of previous image.
Learning to recognize what these blacks are could be crucial to a prospectors economic future.
