Simple set-up to measure the melting point of ice, not most effective method. Shows set-up of retort stand, thermometer funnel and flask. same image also shows a simple filter set-up... Original idea from From GENERAL SCIENCE BY BERTHA M. CLARK, PH.D. (Gutenberg EBook 16593) black & white 实验 筛选器 蒸馏架和温度计
