<p>[QUOTE=&quot;springfld.arsenal, post: 141077, member: 54&quot;]Scratch test results:&nbsp; Material is very hard, in pic left scratch is a shallow one made by two strokes of sharp steel tool with 20 lbs. pressure.&nbsp; Right scratch is a deep one made with same tool but eight strokes with 20 lbs. pressure.&nbsp; Had to use flash on camera to get decent image, but otherwise photo is undoctored but cropped Iphone6 pic.&nbsp; I will let you analyze what the color in the scratch may mean, I don&#039;t want to influence your analysis.</p><p><br /></p><p><img src="https://springfieldarsenal.files.wordpress.com/2016/05/image19.jpeg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
