The marker pen is a pen that has a tip made of porous, pressed fibers felt and a reservoir of colored ink. This reservoir has a core of an absorbent material which carries the ink. One more necessary part of a marker is a cap that prevents drying of ink in a nib. The ink of a marker has a solvent in it that keeps it in liquid form. Until the s, that solvent was toluene or xylene. These solvents are harmful and because of that, we today use alcohols instead.
The oil company would have been a job with a prestigious company. This was the job I was counting on. But I was eager to relocate my young family to the Chicago area, so with nothing else going for me at the time, I took the interview.
I soon received an offer from Sanford with a slight raise in pay, and since it was the only good offer I had, I accepted it. Shortly after accepting the Sanford offer I received an offer from General Electric. They were developing a color television tube and needed an analytical chemist who was capable of developing new analytical procedures.
In my interview with them I had impressed them as someone with the ability to work in uncharted territory. The job was not only in Cleveland, but within walking distance of the apartment where we were already living. It was a great offer and a great opportunity. But my first objective was to relocate my young family where my children would grow up knowing their extended family.
To me, this was my highest priority, so I turned down General Electric and honored the commitment I had made toSanford. By all sound logic I had made a poor choice. And now that I am at the end of my career, I still have to wonder what I missed professionally by making that decision. From my first day on the job at Sanford it was made clear to me that the President of the company, Charlie Lofgren, considered the Sharpie to be the future of the company.
My training began by Keith walking me over to the production line where Sharpies were being made. A team of about 4 assemblers sat at a table. The first assembler manually inserted a plastic fiber bundle that was nothing more than an overgrown cigarette filter into the molded plastic housing.
These parts are known as the barrel and the reservoir. The barrel was, and still is, grey in color. Another smaller plastic piece known as the ferrule was then manually placed on the barrel and this assembly was handed to the second assembler. The ferrule was colored to match the color of the ink being used. This assembler set the assemblies into a fixture know as the spin welder.
Upon activation of a switch a rotating head came down and spun the ferrule at high speed while holding the barrel stationary in a clamping device. The friction of the spinning ferrule against the stationary barrel created enough heat to very quickly melt the plastic parts together.
Sanford, Jr. Focused on selling ink and glue, the company expanded in and moved to Chicago. After a ruinous fire in , Sandford rebuilt its factory and HQ, and started going from strength to strength.
