      this is a 100% good oak A tarn. It was washed and there is some zone (1-2) where paint is missing (is not rare also in period photos).

      The tarn glows, sure with a light brightness, but glows.

        Hi to all,

        I have made some experiences with UV light to a brazilian militaria forum and I find some interesting results with them. http://www.ommb.com.br/forum/viewtopic.php?f=20&t=4849

        1 - I submerged a half piece of a modern white twine in a detergent with optical witheners and after it the half submerged twine glows like a neon light:





        Conclusion - White natural fibers in contact with modern detergents with optical witheners will be glow under UV light.

          2 - I submited these two red post stamps from 1934 and 1939 respectively under UV light...



          ...and both stamps glows in a fluorescent orange under UV light:





          Conclusion: Red fluorescent pigments was in use since the early thirties.

            3 - I had made some experiences with 11 diferents modern white sew lines:





            And the results are:

            - 5 samples (45,5%) glows under UV light and produces solid material at the burn test.

            - 3 samples (27,3%) glows under UV light and produces ashes at the burn test.

            - 2 samples (18,2%) don't glows under UV light and produces solid materials at the burn test.

            - 1 sample (9%) don't glow under UV light and produces ashes at the burn test.

            Conclusions:

            - Some modern sew lines or cloths are mades with synthetic materials and don't glows under UV light.

            - There are some modern sew lines and cloths don't mades with synthetics materials but glowing under UV light.

            - Some modern sew lines and cloths can don't glows under UV light and produces ashes at burn test like the 65 years old materials.


            In my opinion UV light test and burn test are importants like auxiliar tools in the originality research, but not all conclusives to accept or discard an item.

                i put very a very small quantity powder soap (for washing machin) on the right wind then, with a finger and few water, I rubbed slightly for a few seconds.

                Now if i put under UV lights... this fake eagle doesn't shine.
                It shine only where i lightly washed it.

                    This is all well and good. I think we can conclude that the UV is not the ultimate test, it is just one test in the toolbox -- as it is in forensic science.

                    I don't like items that have been washed anyway. To me, that is almost as bad as fake.

                    And when I see an SS tab that's aluminum thread's white core glows, I become exteremely suspicious. The same with an armband that has glowing white threads. During the TR, thread was not usually treated with whiteners.

                    If you really want to have fun with UV, take one to your next hotel visit and scan the sofa, blankets, carpet, etc. and ask yourself what all those glowing spots are. Then put on a body condom for the rest of your stay.

                      ...i don't have problem if an item was washed... most of the times... you can't realize it!

                      UV it's for sure a great test for paper items such as posters.

                      But... not the final.

                        black light tests

                        One of the urban myths about the black light test is that artificial fibers glow and that the Germans never used man made fibers. Considering that the German chemical industry invented Rayon, that is hard to accept. The Germans invented the modern phosphate whiteners and they were patented just before the war. The black light test is valid only for the color white and no other. These whitiners were in the stream of commerce for cloth circa 1940. The Military Advisor article that is reproduced in the thread, conceded that the inner white core of original SS cuff bands could and did in fact glow. This is hidden in the article, but is there as a subscript to a photo. This picture is posted in the thread. The black light test is valid. The operative date for cloth is not after 1945, it is after 1939, when the patents were issued for phosphate whiteners.

                            To post images you have to be an association member, which is a $25.00 fee but well worth it in my opinion. You would post your SS titles here for review:

                            http://dev.wehrmacht-awards.com/foru...splay.php?f=35

                            Just start a new thread once you've paid your fee and you're on your way.

                            Hope this helps.

                                You're right! For one, I know there's an excellent professional article on the subject posted somewhere here. It has some really eye-opening revelations in it. Currently, I can't find the thread, but it is well worth searching for, for sure.
