The acetate of cellulose is a natural modified polymer, obtained from processing with acetic anhydride the more diffused polymer in the vegetable kingdom: cellulose.

It is extracted from the wastes or bows of cotton. Nowadays barks and wood of poplar are mostly used. Anyway, this is an almost entirely natural product. In order to get a plastic material with appropriate physical and mechanic characteristics, the acetate of cellulose is mixed up with solvents and specific additives, as stabilizer to light and heat, dyes and plastic materials (ethylene, in particular).

The standard material is the common acetate, obtained by extrusion; then, there are the sheets used to manufacture luxury combs: the rhodoid (which, after the extrusion in monochromatic foils, is pressed to form a complete block from which plates are cut out; this is defined lamination process). The more used colour is the tortoise (imitation turtle), but we also have monochromatic plates (black, red, transparent or fantasy).

The production of combs starts here, but before arriving to the comb in the shape we all know, we have to go through a dozen of productive processes, which begin with the cut of the comb outline and finish with the stamping and the final control.

1. Cutting of a piece from the sheet
2. Shaping of the comb
3. Polishing of the edges
4. Bevelling of the teeth
5. Cutting of the teeth
6. Crailing teeth base
7. Polishing of the comb and the superior part of the teeth
8. Rounding of the teeth end – with pumice
9. Brushing and polishing of the teeth
10. First polishing by tumbling
11. Last polishing by tumbling
12. Gold printing and final control
