As the 20th century drew closer, companies redesigned the containers for their products. Proprietors and bottle manufacturers continued to create variations on classic designs. Form became the clue to function as embossing became less common. Medicine bottle manufacturers of earlier eras left a legacy of designs and forms of great beauty and variety.

Their crudity beckoned to the days of the log cabin when everything was hand-made. The "modern" bottle was far less exciting, less individual and reflected the changes in American society. The industrial age was in full swing. Production and uniformity became the goals. The bottles below fall at the very end of the hand-tooled era. Glass blowers began forming unions in response to the threat of mechanization.

The common "green glass" so long the medium of choice had within the span of a few short years nearly disappeared. Things were changing.
