Fire polishing is a method of polishing a material, usually thermoplastic or glass, by exposing it to fire or heat. By melting the surface of the material, surface tension smooths the surface. Operator skills are very important with this method. When done correctly, fire polishing produces the clearest end result, especially when polishing acrylic. This method is best suited for flat external surfaces. Fire polishing is often used in acrylic plastic fabrication because of its high speed when compared to abrasive methods. In this application, a torch that burns hydrogen and oxygen is usually used, one reason being that fire chemistry is unlikely to contaminate plastic.
Fires are very important for the manufacture of glass pipettes used for clamping technique of voltage clamp.
