To be complete, I did cover indurated fiber and the different company's history. Indurated fiber (though first used for "fibreware" was also later used form electrical insulation. The section covering fiber can be found at the link below: http://antiquesockets.com/bergmann-sub-section-insulating-materials.html#VulcanizedFiber It is a long illustrated section and indurated fiber is covered in several different areas as you scroll down. The main link to where indurated fiber is covered is found here: http://antiquesockets.com/bergmann-sub-section-insulating-materials.html#indurated4 Other miscellaneous areas are listed below: http://antiquesockets.com/bergmann-sub-section-insulating-materials.html#indurated1 http://antiquesockets.com/bergmann-sub-section-insulating-materials.html#indurated2 http://antiquesockets.com/bergmann-sub-section-insulating-materials.html#indurated3 I hope that this helps you.
