    Jbauries Impts. in the Manufacture of Artificial Teeth and Gums. the plate and teeth. A plate and teeth having been made and com¬ bined as above explained, this part of my Invention consists of forming gums on the-plate, and at and around the roots or lower parts of the teeth, where they are fixed to the plate by using by preference the vitreous compound above described; this forming of the gums is readily 5 performed by the hands with modelling tools; and having formed the gums with the plastic matter it is allowed to dry and to set, and then is subjected to heat, so that the vitreous enamel will adhere to the metal plate and to the lower parts of the teeth, and will form artificial gums thereto of a very cleanly description. In applying heat care is 10 to be taken that the raising and also the lowering the temperature be done gradually. The vitreous compound above mentioned may be varied, but I believe that which is above given to be the best for the purpose; and the same will have coloring matters mixed therewith as similar vitreous compounds heretofore have had when used in making 15 mineral blocks sometimes called gum teeth, wherein metal plates and artificial teeth are not combined. Having thus described the nature of the said Invention, and the manner of performing the same, I would have it understood that what I claim is, first, the use of asbestos, as herein described; and, secondly, go I claim the forming of artificial gums to artificial teeth fixed to a metal plate. In witness whereof, I, the said George Laurie, have hereunto r 1 v *' * * f.. y set my hand and seal, this Thirteenth day of April, in the year of our Lord One thousand eight hundred and fifty-four. 25 >r * w • ' « T.
