The first was condensing distilling machine used make the phenol
resins used make the disc blanks.
This machine would have been made the laboratory staff from plans drawn
up experimenters—probably Edison, Sam Moore, and Fred Ott—and copied from
existing distilling machines and heated mixers.

At the bottom the container was valve draw off the hot liquid and a

This created the thick resin, called condensite, which when cooled, could made
