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.
These are decorative markers that are set into the fretboard. These could be simple, dot markers to indicate the 3rd, 5th, 7th, 9th, 12th frets, or complex, decorative designs. At the end of a neck, youâll find a headstock. The headstock is the bit at the end of the guitar where all of the strings end.
