TOOTH SAMPLES - Detail from a circular shade guide of mineral teeth. Mineral teeth came in a variety of forms, sizes and colours including tube, pivot, vulcanite and flat teeth. The Claudius Ash catalogue states that mineral teeth were 'free from porosity and can be ground and polished to any extent that may be necessary to suit special cases'. The shade guide enabled the dentist to place any tooth against those in the patient's mouth and to simply write the number of the shade down for easy ordering. This shade guide includes 25 different shades. (Photographed at the BDA Museum by Filip Gierlinski. www.filskifoto.com
