The stage-forceps was a commonly supplied accessory with many microscopes, especially of the 19th century. It was suitable for holding a leaf or an insect etc. It has a fitting with a cork on the other end to which an object could be pinned. It would not be suitable for holding a hard object like a mineral for which Vice-Forceps or a 3-pronged tenaculum or Mineral Forceps would be better suited. More complex apparatus for detailed examination of minerals and determining their optical properties such as stage goniometers and integrating stages became available later in the 19th century.
