Singing bowls are also sometimes said to incorporate meteoritic iron. [17] [45] Some modern 'crystal' bowls are made of re-formed crushed synthetic crystal. [17] The usual manufacturing technique for standing bells was to cast the molten metal followed by hand-hammering into the required shape. [32]
A glass harp, an ancestor of the glass armonica, being played in Rome.The rims of wine glasses filled with water are rubbed by the player's fingers to create the notes.. The name "glass harmonica" (also "glass armonica", "glassharmonica"; harmonica de verre, harmonica de Franklin, armonica de verre, or just harmonica in French; Glasharmonika in German; harmonica in Dutch) refers today to any ...
It is also possible for quartz clocks and watches to have their quartz crystal oscillate at a higher frequency than 32 768 (= 2 15) Hz (high frequency quartz movements [4]) and/or generate digital pulses more than once per second, to drive a stepping motor powered second hand at a higher power of 2 than once every second, [5] but the electric ...
A Toast To Christmas with the Singing Glasses is an album recorded and released in 1980, composed and performed by Gloria Parker. Fourteen well-known carols are performed with the glass harp producing flute-like sounds on crystal glasses, marking the first commercial album to use glasses as a musical instrument.

Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.
Within surface science, a quartz crystal microbalance with dissipation monitoring (QCM-D) is a type of quartz crystal microbalance (QCM) based on the ring-down technique. It is used in interfacial acoustic sensing. Its most common application is the determination of a film thickness in a liquid environment (such as the thickness of an adsorbed ...
