Book excerpt: Excerpt from American Journal of Pharmacy, 1861, Vol. 9 With us, the demand has become quite frequent of late for silver and gold coated pills, several eminent practitioners prescribing this elegant finish, and we have acquired some experience in the manipulation. The above represents an apparatus we have had turned to order from hard wood for use in this process. In rolling the pills, care is taken to use no dusting powder of any kind, and to have them moderately damp, otherwise we moisten them with a little syrup, and then introduce them into the hollow sphere along with the requisite quantity of silver or gold leaf; a rapid motion is now given to the globe, and in a few seconds the pills are removed with a clear and bright coating. One dozen pills of average size, require one sheet of foil, and larger numbers in the same proportion. Some difficulty is experienced in giving a handsome coating to pills of Quevenne's Metallic Iron, on account of their black color; this can only be obviated by the use of a larger proportion of foil, which may be objectionable as interfering with their solubility notwithstanding its extreme tenuity. The taste of the pills is of course disguised in proportion to the completeness of the coating; in dispensing, no powder is necessary, the tendency to adhere to each other being obviated. Some of the old recipes direct to use a gallipot laid against the palm of the hand, for coating pills with the foil. We have found two porcelain capsules fitted to each other, the opening at the lips being covered by the thumb, to serve a very good purpose; but there is a decided saving in the use of an apparatus as above figured, any portion of the foil not adhering to one charge of pills will be ready for the next, besides the advantage which is gained by the leverage of the handle.
