Abstract: Thermal analysis is an analytical method that contains a wide variety of essential approaches that study the materials by testing their properties variations with the variation of heating and time. Many thermal techniques are available for characterisation of many of the thermochemical and thermophysical features of the materials. Thermoptometry is one of the thermal analysis techniques that defined as a family of thermoanalytical techniques where an optical feature of the test sample is monitored with time and/or temperature. Some thermal transitions cannot be understood accurately with common thermal analysis techniques. Hot-stage (thermal) microscopy is the blend of microscopy and thermal investigation to allow the properties of the materials to study with heating and time. Besides determining details about particle size and particle morphology, the optical evaluation offers useful data about the substance under testing relating to glass transition, melting transition or various other thermal changes. Thermal microscopy provides an excellent possibility to visually observe thermal changes.
