I am adjusting the film to a specific element number. The numbers can be seen in the small window just above the viewing lens.
Due to the need of adequate lighting for these pictures and not be exposed to the fumes I conduct these assays outside.

I am watching as I adjust the sample into the electric arc. There is a welder’s type lens mounted on the vent hood that allows me to see the sample moving into the electric arc without damaging my eyes.

While the mineral sample is being melted and/or vaporized I am looking into the lens viewer to see what elements may be present.
Since these images were taken I have purchased a long/large weather resistant outdoor table that allows me to have all the associated expendables, hand tools and note papers.
