1. Introduction to the subject of glass technology. 2. Glass, vitreous state, glass structure. 3. Properties of molten glasses - viscosity, surface tension, density, crystallization ability. 4. Glass properties 1 - mechanical properties (glass strength, hardness and brittleness), thermal properties (temperature expansion, thermal conductivity and specific heat capacity). 5. Glass strain, charge, glass raw materials. Batch preparation and its establishment. 6. Staining of glass in mass, raw materials - dyes, their distribution, cause of coloration. Examples of staining. 7. Basics of glass melting I: - chemical reactions during glass melting, dissolution of solid substances in the melt, principles of crystallization and gas solubility. 8. Basics of glass melting II: - flow and homogenization of enamel, sowing of enamel and its finishing. 9. Ecology of melting and evaporation of volatile components. 10. 10. Melting aggregates - their division according to the method of operation, regeneration and heat recovery, used refractory materials, glass pans. 11. Gas and all-electric studio glass furnaces, their advantages and use. Smelting in a studio ladle furnace. 12. Manual shaping of enamel I: glassmaking tools and accessories, the principle of filling and shaping glass on a pipe, meaning ring, principles of enamel collection and treatment. 13. Manual shaping of enamel II: glassmaking tools and accessories, the principle of filling and shaping glass on a pipe, meaning low thermal conductivity of the ring, principles of taking and treating enamel, glass molds, requirements for them, types forms and their characteristics. The student will understand glass as a material with exceptional use for artistic purposes. This is due to the properties of glass and theirs connections with the composition of the glass and its glass structure. The student will gain a real insight into the possibilities of glass in the art world and general use. This knowledge then allows him a much better orientation in the possibilities of its use. Knowledge, respecting and correctly using the extraordinary properties of glass is necessary for the successful implementation of the project and also enables effective consultation with glass experts.
