The interrelation of the surface tension and viscosity of glass melts is examined from the physical-chemical and technological standpoints. The corresponding relations and experimental results are presented. The interrelation of the surface tension and viscosity is also examined for technological processes: glassmaking, interaction of molten glass with refractories, formation of different types of glass articles, thermal polishing and edge melting of articles and foaming during the production of foam glass. © 2014 Springer Science+Business Media New York.

Work on colloidal coloring of glass by metallic and nonmetallic nanoparticles is reviewed. The particulars of the technology and the character of glass coloring are shown. The experimental and practical results obtained are discussed from the standpoint of nanotechnologies. © 2011 Springer Science+Business Media, Inc.

The main conditions for colorants to dissolve in glass melts-chemical interaction, diffusion, distribution in bulk or in a definite layer-are examined. The particularities of continuous volume and surface coloring of glass in container-and sheet-glass production are noted, and the corresponding dependences are presented. © 2013 Springer Science+Business Media New York.

Materials for the most widely used colored glasses are analyzed according to types of coloring and color centers. Selenium coloring of glass is examined in greater detail from the standpoint of the current understanding of the structure of pigments and the formation of color centers. A more precise classification of the types of coloring and color centers in glasses is presented. © 2012 Springer Science+Business Media, Inc.

The primary types of colored glass and redox interactions are examined. Kinetic relations are presented and the conditions for conducting processes with the participation of colorants in batch and melt and during congealing of glass during molding of articles are analyzed. The spectral characteristics of commercial glasses are analyzed. It is shown that the light-protective characteristics and diathermancy of colored glass used in the production of glass wares can be evaluated. © 2016 Springer Science+Business Media New York
