Cryogenic freezing has been found to increase the life of steel tools by two to five times. In 1985, the Cryogenic process was applied to a set of piano strings. Almost 3 years later, the piano remained accurately tuned. What is cryogenic freezing? Well, in this process, the guitar string is treated to temperatures below -300 degrees Fahrenheit. (That's -2,100 for a dog, but they usually prefer cat gut strings.) The subzero temperatures produce changes in the molecular alignment of the metals of the strings. This is thought to extend string life and enhance the tonal brilliance. Although many manufacturers produce a Cryogenically Frozen set, the most well known are the Dean Markley Blue Steels. |
