For now, Eisen just figured he wanted to try the idea that he had for this out, but for that, he of course needed to first make the mechanism to actually make the molten glass and then push it out in certain amounts so that it could be used for the bottles.
Usually, the way that this was done was by pushing out a steady cylinder of molten glass out of a hole and have a blade cut it up in steady intervals so that everything would be the same size.
