Manganese Glass Door Knobs

Pair of 8-point glass knobs with one brass bezel finish and one chrome. At least one of the knobs has purple tinting from manganese. Manganese is one of the oldest glass additives and was used in small quantities to de-colourise (remove the green tint from glass to make clear) and in higher quantities to colorize glass.
