The American Zylonite Company

To navigate the enlarged images, when you have selected one, either use the 'Back' and 'Next' buttons to move to other images, or click on the Zylonite trademark in the top left corner to return to the correct place in this page.

There is some question as to the manufacturer of those items marked with a yellow border. They are marked 'ZYLONITE' but lack the arrow of the trademark. They have a two digit number below the name e.g. '00', '59' '69'. There are almost identical items, but made in shellac thermoplastic composition, bearing the name of The Florence Manufacturing Company. There are various possibilities. a) The items were made by Zylonite for Florence. b) The Zylonite Brush Co bought the moulds from Florence. c) After the demise of Zylonite, Florence used the Zylonite trademark for its 'Celluloid' products. The last is unlikely as the ZYLONITE name continued in use, for dice, by The Celluloid Company.

Hair Ornaments

The box, shown below, contains 21 unfinished hair ornaments (combs), not hair brushes, as stated. None of the items are marked with the Zylonite trademark. But, they are packed in the original tissue paper and they are the correct color (Carnelian), so it has been assumed that they are Zylonite products. The box is illustrated in detail as it contains much useful information, the three Spill patents, and a superb engraving of the factory. The 'United Zylonite Company' is, presumably, the corporate entity that owned the 'American Zylonite Company' and the other smaller subsidiary companies.

Water Proof Cuffs (Box)

Collar or Cuff Studs.

This group consists of several hundred studs and many fragments of packaging. The two fragments, shown below, have been used to make a conjectural reconstruction of the original card containing a half dozen studs. Each stud is 12mm. across the base and 8mm. across the top. See last image for magnified individual stud.


This box of one dozen dice looks like an early product of The Celluloid Company. Presumably these dice were originally manufactured by The Zylonite Company and become well known as 'Zylonite Dice'. The Celluloid Company continued production, putting "ZYLONITE" in quotes. denoting it as a description rather than a tradename. There are similarly named Poker Dice that look quite modern in appearance.
