Soil Chromatography 2: Hampden Baltimore MD

Soil Chromatography 2: Hampden Baltimore MD

Soil chromatography is a photographic process. Finely ground soil is absorbed by filter paper that has been prepared with silver nitrate, and spreads by capillary action, and a 'picture' of the soil appears.  The soil used here is from Stony Run Park in Hampden, Baltimore, MD.

 

The image is framed in a two sided glass display- 5" diameter
