COLORING MATERIALS. 



The use of colors which contain any metal except iron and the use 

 of gamboge, picric acid, and all aniline derivatives for the purpose of 

 coloring food and food products is forbidden. 



For coloring toys, preparations containing arsenic, antimony, lead, 

 cadmium, copper, cobalt, nickel, mercury (cinnabar excepted), zinc, or 

 gamboge are prohibited. The use of other metallic colors for coloring 

 toys is permitted, provided the color be coated with a waterproof var- 

 nish. The colors whose use is forbidden with toys may be employed 

 with earthenware, provided they are covered with a glaze which is 

 burned in. 



The use of poisonous colors, such as arsenic preparations, with arti- 

 ficial flowers and similar substances, is forbidden unless the article be 

 covered over with a waterproof varnish. Wall paper and similar 

 material must not be colored with arsenic preparations. 



The sale of food which has been prepared in vessels coated with 

 poisonous colors, or stored in receptacles so coated, is prohibited. The 

 importation and sale of wines colored with aniline dyes are prohibited. 

 Foods and food products which are themselves white or colorless (con- 

 fections, beverages, etc.), but which are ordinarily artificially colored, 

 may be colored by any of the following substances, provided the 

 articles so colored shall be sold from the factory only in the original 

 packages which are distinctly labeled with the name of the material 

 employed for coloring the contents of the package, and also with the 

 registered seal or trade-mark of the manufacturer. The label must 

 also bear a statement from a prescribed official laboratory (Chemischen 

 Hochschulinstitute) that the contents of the package contain no sub- 

 stances deleterious to health. This statement must bear a later date 

 than the latest decision of the health office regarding the subject and 

 must be renewed at least annually. The list of aniline colors which
