　　What is fire polishing in glass blowing?

　　Fire polishing is a technique employed in glass fabricating. It also known as flame polishing, is a method of polishing a material, usually glass or thermoplastics, by exposing it to a flame or heat. There are many advantages.

　　What are benefits of fire polishing?

　　Firstly, flame plastic polishing produces the clearest finish, especially when polishing acrylic.

　　Furthermore, flame polishing is frequently used in acrylic plastic.

　　Next, fabrication because of its high speed compared to abrasive methods.

　　In addition, we should know the temperature of fire polishing so that we can use it easily.

　　What should the temperature be to polish glass?

　　Use 1,300 degrees as the polishing temperature and maintain this high heat no longer than 20 minutes so that you do not inadvertently distort the glass.

　　A general polish procedure is to heat the kiln at a rate of 400 degrees per hour until it reaches 1,000 degrees, and then hold it there for 20 minutes.

　　In general, fire polishing glass is a method that glass workers use to garner a smooth and glossy appearance on their works. The process is best used on acrylic or glass with curved or sloped surfaces. Flame polishing is essential to creation of the glass pipettes used for the patch clamp technique of voltage clamping.
