2016-01-09 (Sa) Acetone Vapor Bath Experiment

Judging by yesterday’s results it seemed important to use an analog clock rather than digital timestamps since the hand movements can be recognized while moving quickly unlike a digital readout. A small analog watch was purchased but its coloration made it difficult to see in bright light so the movement from an inexpensive clock was taken. The second hand was removed to avoid distraction.

Salvaged clock movement

Keeping the subject close to the camera lens was important to see changed details while processing. The clock movement was placed in a small bowl so it would be visible through the glass plate during observation.

Items were arranged so the movement, was visible next to the plastic parts for processing and both were visible through a camera. Space in the camera shot was not wasted.

A paper towel was cut to size, 2” x 2” (50mm x 50mm) and soaked in acetone until it was saturated. The uniform size of the paper towel was important for repeatability. A specific volume could have been used as measured by a precise measuring syringe, which was on-hand, but the paper towel method can be repeated by anyone not fortunate enough to have precision equipment available.

Paper towel absorbing acetone

The acetone saturated paper towel was placed in the processing chamber and held to the ceiling with magnets on the inside and outside of the glass. Magnets coated in nickel were not damaged by the acetone.

Test chamber processing

Time lapse photos were turned into a movie clip and uploaded to YouTube. Video does not have the subject in focus so changes were not apparent. A photo was taken after processing overnight. The processed pieces, on the right, appear glossier than the control pieces. This method will add a sheen to printed pieces.
