The purpose of the work is to develop a multicomponent formulation of modifiers for master alloys of 18-karat white gold with the necessary set of technological, physical, mechanical and economic parameters and properties. Work has been carried out on the manufacture of prototypes of multicomponent alloys of 18-karat white gold, the dependences of the chemical composition and microstructure, their influence on the main physical, mechanical, technological and operational properties have been studied. The tasks for further improvement of the composition of master alloys of white gold alloys, their production technology and properties are determined.

This article includes tasks in various areas of functional literacy (reading literacy, mathematical literacy, natural science literacy, global competencies and creative thinking). All materials are united by a common theme: "Metals". The tasks are designed for students of grade 9. The work is aimed at developing the individual's abilities to formulate, apply and interpret knowledge in a va-riety of contexts. The illustrations used in the work are taken from open sources on the Internet.

The article discusses the methodology of teaching primary school students to solve problems involving solutions, mixtures and alloys, with the aim of attracting schoolchildren's interest in learning and improving the quality of education
