Between 1% and 15% of people globally are affected by kidney stones at some point. [14] [15] In 2015, they caused about 16,000 deaths worldwide. [16] Some of the oxalate in urine is produced by the body. Calcium and oxalate in the diet play a part but are not the only factors that affect the formation of calcium oxalate stones.

Goldschläger is a Swiss cinnamon schnapps (43.5% alcohol by volume or 87 proof; originally it was 53.5% alcohol or 107 proof), [1] a liqueur with very thin, yet visible flakes of 24-karat gold floating in it.

Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4.This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4).
It is also known by other names such as "composition gold leaf", "Dutch gold", "Schlagmetal" and "Schlag leaf". [1] It is very malleable and ductile and so can be beaten into very thin sheets. These sheets are sold for use as metal leaf or imitation gold leaf. [2] The addition of arsenic produces an alloy with similar properties but coloured white.
