Original Message:   Re: Car battery case material

Hi Rosanna, Here is a photo of the test made this morning. The pendants are quite dirty so initial passes were indeed a dark brown to yellow. I have now cleaned this one pendant a bunch of times over several days and am confident now that the tests are completely uniform that this is the correct simichrome reaction - or perhaps simichrome will endlessly pick up traces of degraded rubber. I don't know! My best, Linda Copyright 2024 All rights reserved by Bead Collector Network and its users
