WEEK 6 - Glass

This week I am beginning trials with the material glass. I am doing three tests for each material. I placed a latent print in the center of the glass and started the cyanoacrylate fuming process. I allowed the material to sit in the chamber for six minutes for each trial.  

Trial 1: In the first trial I noticed that I did not leave the best latent print to develop. When comparing the fingerprint I made in the glass to the original print taken with ink and powder, I did not have the entirety of the fingerprint. For this trial, I was able to identify five out of the six minutiae points.

            

Trial 2: The second trial ran much smoother than the first. I was able to get more of the print that I was looking for to compare to my original fingerprints. In this trial, I was able to match all six minutiae points. 

Trial 3: Trial three was the best overall. The fingerprint was the clearest when trying to compare the fingerprints together. I was able to compare all six minutiae in this trial as well.  

Overall this set of trials was very successful. I expected to find all six minutiae points in all three trials. However, I was only able to find all six points in trials two and three.
