This is a glass bottle of pure silver leaf floating in liquid consisting of alcohol and water. The amount of silver in this bottle is microscopic because it, like gold, can be hammered into extremely thin leaf form. Silver leaf may be only 0.18 microns (seven millionths of an inch) thick; a stack of 7,055 sheets would be no thicker than a dime.
After collecting fossils as a hobby for many years growing up, Dave Douglass opened Dave's Down to Earth Rock Shop in 1970 at the age of 20 (with the help of his parents) at 1312 Chicago Avenue in Evanston, Illinois. The shop contained minerals and fossils, mostly self-collected by the Douglass family.
