The least common were inclusions of platiniridium and platinosmiridium; zoning
was not a significant factor in the composition and very few intergrowths were

The loop may be made of platinum wire, but platiniridium has the advantage of
being stiffer, and a cheaper material such as Nichrome will often serve the
purpose. The width of the gap should be adjusted as follows: Hold the loop
horizontal, ...

of such ...
