Talc Talc Talc or talcum is a clay mineral composed of hydrated magnesium silicate with the chemical formula HMg(SiO) or MgSiO(OH). In loose form, it is (in ratio with or without corn starch) one of the most widely used substances known as baby powder. It occurs as foliated to fibrous masses, and in an exceptionally rare crystal form. It has a perfect basal cleavage, and the folia are not elastic, although slightly flexible. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 1 as the hardness of talc. Talc can easily be scratched by a fingernail. Talc
American College of Mohs Surgery The ACMS is open to physicians who have successfully completed advanced fellowship training in Mohs micrographic surgery, pathology, and reconstructive surgery. The ACMS currently has more than 1,300 member physicians. In 1995, an ancillary group called The American Society for Mohs Histotechnology was founded. The organization is composed of more than 375 non-physician laboratory technicians who process the slides evaluated during a Mohs procedure. The purpose of the ACMS is to "promote and advance high standards of patient care" with respect to Mohs surgery and other forms of cutaneous oncology through fellowship training, research, education, and public advocacy.
