Abstract

In this research, we have used four different powders to develop finger print images from glass surface. Those four powders were coal, turmeric, pepper, chilly. These powders were preferred because they are cheap and non toxic. The handling and processing is easy as well. The test finger prints were made on the glass surface of petri plate/conical flask. The powder was sprinkled over the test surface and the images were processed. Coal powder gave the best result.
