Abstract
THERMAL instability during the chemical silvering of glass produces Bénard convection patterns in the deposited silver layer. An unstable condition produced by cooling the silver solution to about 10° C, pouring it over the top surface of glass plates at 25° C. arranged horizontally, so as to produce a layer about 3 mm. thick, gave silver patterns as shown in Fig. 1. A very unusual and pronounced difference occurred in the details of the shapes of the convection patterns when formed in the presence of a magnetic field.
