He dubbed it the Magic Marker and it became widely popularized. Permanent markers: Sharpies are by far the most popular permanent marker brand and most people refer to all permanent markers as sharpies. In , the Sanford Manufacturing Company introduced the Sharpie marker, marketing it as the first pen-style permanent ink marker. The most popular brand of washable markers is Crayola and they were introduced in There were only 8 different colors of marker at this time.
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. The product then passed to the third assembler who positioned the assembly in another holding device and activated a foot peddle.
This dropped an automatic syringe down and 2. A forth assembler received the marker, placed the tip into the ferrule and placed the assembly into yet another holder. Another foot peddle was then used to drop a jig down that pressed the tip to just the right height. This final assembler then put on the cap which also matched the color of the ink, and placed the finished marker into a partitioned carton.
There was room for 12 rows of 12 markers in each carton. A finished carton was one gross of Sharpies. The spin welder, the automatic syringe and the tip setting device, known as the staker, each handled two markers at a time, This production line of four workers could with this process produce about markers in an 8 hour shift.
One of the first assignments that Keith Beal gave me was to prepare lab samples of Sharpies that had the ferrules attached to the barrels with an adhesive in place of being spin welded. Since the barrels and ferrules were molded with nylon, I completed my assignment using liquid phenol to make a solid bond between the plastic parts. I reported, however, that this would require very precise placement of just the right amount of adhesive to make a good, clean bond.
And at best this was a process much slower than spin welding. The next thing that Keith Beal did after I joined the company was to hand me a set of dye samples from Ciba Geigy. And with that I sent to work. The assignment was not a formal one.
But even if there had been a schedule, it would have been meaningless because not long after that Charlie decided that his company did not have the resources to make its own proprietary Sharpie tip. This left me with some unfinished spirit soluble Sharpie formulations, and no reason to continue their development. And then after a set of circumstances developed that will be described in the stories included, The original Sharpie was replaced with a product that looked exactly the same, but was made with entirely different materials.
