The necessary theoretical knowledge and properties of glass, which are necessary for solving the design of the forming tool, are listed. technological methods of glass forming are mainly press-blowing and forming with a double-blowing system. With the help of the described tool, glass can be relatively successfully shaped, which is inserted into the tool in the shape of a plate. The glass plate, which is bent into a cylindrical or hemispherical shape, is placed on the press and heated with a flame until the glass is sufficiently soft to work with.skhttp://creativecommons.org/licenses/by/4.0/glassforming toolheatingconstructiontechnologyArticlehttps://doi.org/10.26552/tech.C.2023.2.9
