It has been found that the principle applied in the case of ebonite articles can be readily applied in the case of a large number of articles if suitable solvents (swelling However in all cases care has to be taken, that the massv of the articles to be metallized is slowly swelling-in the solvent of the reducing agent and the reducing agent is sutfi- 0 ciently soluble in the said solvent, but does not obstruct the swelling operation-of the article to be metallized and that, after dipping the article into the reducing solution and subsequently drying the same, the orig'i-I nal shape of the said article is' not changed inany way and the article retains the reduclng agent.

' In case it isflnot desired to metallize the whole article, the places which'are not to be covered with metal are covered with a coat-;-
ing, which does not obstruct the processfof metallization, but is metallized and thus protects the part of the article below the same and can bp readily removed'withthe non-' required metal coating after the completion of the metallization with the result of sharp boundaries. Care has to be taken thatthe andin' certain cases also an asphalt-lac can be used.
The following materials are well adapted for metallizing the articles .formed therefrom 7 L Products of condensation ofcasein, for instance, with formaline, galalith; products of condensation of phenol, for instance with, formaline, bakelite, aswell as diverse mixed products. of which at least one component can sufficiently be swelled up in the suitable reduction solution.
