The state of aggregation of the solid occasionally affects the interfacial surface tensions sufficiently to alter the distribution between two immiscible liquids. In the case of gold, blue gold will pass to the dineric surface ether-water, whilst brown gold will remain in the aqueous phase, A protective colloid (see p. 200)... 

Red tones can be achieved through the use of a direct toner, such as GT-15, or by combining toners. Try a combination of Ansco 221 Sepia Toner and Blue Gold Toner. Follow the directions published with Ansco 251 Green Toner for washing between processes. 

This time I was forty-five years old and in a group in a ritual setting. As I began to feel the effect of the mushrooms, a wonderful feeling of relaxation came over me. I was seeing beautiful patterns synchronized with the music. Some of the patterns appeared like Jewish letters and symbols streaming across in blues, golds, and silvers, colors I associated with Jewishness. This seemed to validate my recent explorations of my roots and my intentions to celebrate the Sabbath and Rosh Hashanah.

Absorption Spectra. — The absorption spectra of red gold solutions were found to correspond well with that of ruby glass first by the author and since by many other investigators. In deep red or purple red solutions the maximum absorption lies near the spectral line E. In the case of blue gold solutions the maximum lies nearer the red end of the spectrum. The absorption band is also wider, and the refracted light from the particles is yellow or brown.

On the jewelry materials side, there has been considerable development of alloys tailored to the requirements of specific manufacturing routes and end-market needs, such as alloys for investment casting, microalloyed high karat gold, and alloys designed for special color effects such as black, brown, and blue gold produced by oxidation.
