The invention provides a visualization miniature method and apparatus for testing mineral temperature reconstruction. The invention mainly carries out mineral rapid heating and mineral phase observation simultaneously. The main apparatus of the invention comprises a heating furnace, a temperature control cabinet, a computer, a mineral phase microscope, an image acquisition system and a gas mixing system. The experiment process is as below: preparing the ingredients, mixing well, turning on the computer, mounting the platinum wire while correcting positive and negative electrodes of platinum wire, placing a sample in a glass dish, mixing the sample with alcohol uniformly, placing part of the sample to a platinum wire heating zone, adjusting a heating system, heating, and saving the image by a phototropic vision, and carrying out subsequent analysis on the phototropic vision images by a pieces of image analysis software. The method and apparatus can obtain usual reaction start temperature, melting end temperature, rapid solidification temperature, as well as melting rate and solidification rate. The method has the characteristics of intuition, convenience, fast, good reappearance, easy operation and small error.
