Filmed sequences of laboratory operations have been used to produce a series of video segments, each one detailing a procedure or procedures required for safe, effective research in the experimental petrology laboratory at the American Museum of Natural History. We have compiled detailed, illustrated "how to" texts that describe each of these procedures. Tutorial presentations are hosted on Vimeo, which facilitates direct download by people interested in these techniques.
Segments with live links to vimeo video tutorials:
1. motivation for experimental petrological investigations using the internally heated pressure vessel (IHPV) and cold-seal pressure vessels (CSPV)
supplementary documents
2. capsule preparation and subsequent capsule welding and loading
