Experimental piezoelectric apparatus
name: label: associated person
content: Curie, Pierre
notes: label: Description (Brief)
content: A Curie quartz piezoelectric balance. Brass housing mounted on a wooden tripod. Adjustable feet, quartz crystal mounted on brass frame. One binding post on top. A replacement quartz mount in a box marked: "Quartz Plate / (Piezo electrie)" was found with the unit. Brass cover marked: "Quartz Piezo electrique / de P. Curie / Societe Centrale de prod its chimiques / 44 rue des Ecoles / Paris / No.255". Serial number may be "25" - the second 5 is indistinct. Columbia University property number P1E3 on unit.
label: Description (Brief)
content: "The principal component of the instrument is a rectangular quartz slab. To pick up electricity, it is silver-plated on both faces and two tin strips are attached. One strip is connected to ground and the other to an electrometer. The upper end of the quartz is attached to a supporting arm. A tray is suspended from its lower end, in which weights are placed in order to exert force on the quartz and so produce charge."

EM.322924 has only three, not four, legs and is missing the weight tray, top connecting screw, and measuring deck seen in figure 4 of the BSIS article. There are no apparent mounting holes on the legs for the deck, however.
