Moonstone is a mineral made from potassium aluminium silicate. It is formed in thin layers, which gives it an interesting light scattering effect called adularescence. The highest quality moonstones come from Sri Lanka.
Mown is the past tense of mow. For example, "He walked past a field that was freshly mown".
The saxophone was invented in 1841 by Adolphe Sax. He wanted to make an instrument with characteristics from both the woodwind family (including flutes) and the brass family (including trumpets). Saxophones are usually made of brass, but are a member of the woodwind family.
The sound in a saxophone is made by a small cane reed in the mouthpiece that vibrates when you blow air through it. The different notes are made by opening and closing holes along the length of the saxophone.
Soapstone is a soft stone that is made up mostly of talc. It feels slightly soapy to touch, hence the name. Because soapstone is so soft, it is often used to carve sculptures and household items from.
