Small‐angle X‐ray scattering (SAXS) studies of the striking gold ruby glasses show that both tin oxide and gold are necessary for a satisfactory ruby. Increasing tin oxide decreases the striking speed, whereas increasing gold concentration increases it. Once the ruby color has been struck, further heat treatment causes little change. The presence of tin oxide aids the nucleation and solubility of gold in the glass. Particles in the glass which struck to purple are fairly large (22 nm (220 Å)). Particle sizes for the livery ruby are >100 nm (1000 A).
