At room temperature, ammonia (NH3) is a highly water-soluble, colorless, irritant gas with a unique pungent odor. Ammonia has a boiling point of -33Â°C and an ignition temperature of 650Â°C. Injury from ammonia most commonly is caused by inhalation, but it also may follow ingestion or direct contact with eyes or skin.
Guitar frets are thin strips of metal that are embedded in the neck of the guitar. They are raised up from the face of the fretboard in order to separate the neck into different semi-tonal intervals. This basically means that each fret indicates a different note. Frets are numbered just like the strings are. They are not, however, numbered by the metal pieces themselves but by the space in between the metal pieces. For instance, the first fret on the guitar is the space between the nut and the first metal piece. The fret wire is commonly made of a nickel/silver alloy, but stainless steel wire, although more expensive, produces longer lasting benefits.
To dress the frets I bolt the neck to a maple plank, which serves as a stand-in for the actual guitar body (below). Then I adjust the truss rod until the neck is as true as possible, and blue the tops of the frets with a magic marker in preparation for leveling.hen this neck was made, the frets were driven into the fret slot from the side of the fingerboard rather than pressed down in. If I were to try to remove these frets by pulling them up, not only would the maple fretboard chip excessively, but Iâd damage the finish bond repair.
