In practice, ninety percent of the engineering faults initiate from the surfaces by means of the mechanisms of fatigue crack wear behavior, corrosion and erosion. In this point of view, researchers are attracted by measuring surface and near-surface zone suitability of work pieces and evaluation studies. Surface roughness is a factor not only in composing the work piece aspect but also in defining the performance of the work pieces in coating processes. In this study, 3 different test specimens are subjected to molten glass that was in forming temperature and the changing surface roughness parameters have been monitored with precise measuring techniques. The obtained data is evaluated by SPSS 13.0 statistical package program. Results are informative about the product quality either.
