103. Silver & Tula Silver Day Cane -Ca. 1900 -Plain and well-proportioned silver knob with a wider, chess board patterned, Tula silver collar both struck with matching Austro Hungarian hallmarks on a 10” long stepped partridge stem extending in a rosewood shaft and a horn ferrule. The style as well as the hallmarks help identifying its Viennese origin and of the glorious Imperial days. -H. 2” x 1 ¼”, O.L. 37” -$400-$600 -Tula, also called Niello is an alloy made of silver, lead and copper adding a certain amount of sulphur. This mixture creates the typical grayish- black enamel like filling. Tula’s melting point (approximately 500 °C) is significantly below that of silver at 800 °C. In order to bring the Tula on to the silver, a pattern must be etched, engraved or cut out of the workpiece leaving gaps. Using an open flame or oven, these gaps are then filled with the melted Tula. Obviously, because this process is very difficult and time consuming, this Caucasian specialty is today almost extinguished.
