Notes:
Used for high temperature chemical analysis. Because of its high melt point and non—reactive properties it is good for high temperature testing.
The wooden crucible holder has two purposes: it is said to hold crucible when not in use, and it is used to reform the platinum metal so that it retains its shape.
