For 10 tests, a total of 180 samples are used on 3 different surfaces and under 6 different temperatures for each test. Four tests have been performed quarterly and a total of 720 samples are prepared. In order to prevent mixing of samples and contamination, information about volunteers were written on labels.
Temperature Values:
Samples taken out from test environment were exposed to temperatures of 50oC, 90oC, 110oC, 150oC, 200oC, 300oC for 3 minutes at each degree.
Fingerprint Development Process: Out of the samples which were exposed to different temperatures; "Super Glue" and "SPR" method is applied to metal and glass samples and "Ninhydrin" method is applied to paper samples to investigate whether fingerprints would develop or …show more content…

"Super Glue" method is used for metal and glass samples and "Ninhydrin" method is used for paper samples which have been exposed to different temperatures to investigate whether fingerprints would develop or not. High quality scaled photo shooting and image intensifying (Photoshop) process is applied to each sample in order to assess if they are suitable for identification or not.
Results of fingerprint samples on different surfaces belonging to each volunteer are classified basing on the classification system used in Turkey and taking at least 13 fingerprint characteristics with regard to they are classifiable or not.
When we assess the study in terms of fingerprint development:
· It is determined that fingerprints on glass surfaces are more suitable for comparison than the ones on metal and paper surfaces..

· When the total number of comparable fingerprints is considered; it is found that the number of comparable fingerprints decreases from month 0 to month
