Not sure, exactly what we are looking at, at the Ferro Foundry, some sort of compactor? Obviously women doing the work with men watching. The first guy on the left looks like he might be a ghost.

Looks like she's putting sand into a sifter...

Sand muller?

Sand muller?

Mulling is a process where the sand to be used in metal casting is mixed with proper components, typically fine sand, clay for a binder, and oil or water.

It is energy intensive work to do with out a machine. Basically mixing the components, and breaking up clumps in the sand. During initial mulling, naturally occuring clumps are broken up. During casting, the heat from the metal tends to bond the sand into clumps, especially that close to the hot metal. It is often necessary to re-mull the sand so it can be reused.

The riddle, or sifter, is used to assure the clumps are out.

They are mulling the green sand.

Ralphs ghost seems to have a jack-o-lantern floating above his head a little to the left. Another ghost to the right of Ralphs ghost, short ghost. Seems like the Non-ghost gentleman farther to the right has motorcycle handle bars floating above his head.

Rosalind P. Walter, the original inspiration for "Rosie the Riveter" died Wednesday at the age of 95.

In regard to the photo of the foundry;

There is a lot of information in that photo if you really look at it. The biggest problem with the photo is focus. Unlike many old photos from back then, the depth of field (the distance from the lens for objects to be in focus) is very short. The photo we saw a while ago of the BIG crankshaft was a really good example of a DEEP depth of field, that whole photograph was in focus.

The men in the background are very much out of focus, thus the ghostly appearance. The woman on the left and the one shoveling sand into the riddle were the most still, and most clearly in focus. The tower that is the most properly in focus and exposed the best. The shovel handle sticking up behind the tower is out of focus .

There appears to be molds, possibly for wheels in the foreground.

The most puzzling thing to me is that BRIGHT spot behind the man and the woman on the left. I wonder if that is a furnace glowing in the background?

"the depth of field (the distance from the lens for objects to be in focus)". Not so. An acceptable, though subjective definition:

The distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.
