Ludwig Ott also carried out experiments involved record materials, including
distilling asphalt residue, which was used filler record blanks.614
The various forms nickel flake and ore samples being analyzed were part the
process testing materials that was crucial the storage battery project.
Albert Petit was involved the project alter shellac with solvents make it
