Beryllium Chloride: Glucina and Sugar Charcoal Ignited in Dry Chlorine (Roscoe 1913)
With charcoal to take the oxygen, dry chlorine turns glucina into beryllium chloride, which sublimes away from the hot zone as white needles.
Result: snow-white needles of beryllium chloride (melts at 440 °C); fumes in moist air and soaks up water.
