Abstract

Glass Rods and Tubes are used to form Glass products using Lampworking Techniques. Borosilicate glass and Soda-lime glass are the most common used glass in forming with lampwork, usually Borosilicate glass is used in Blow forming, while Soda-lime Glass is used in forming with sold rods. Both those types of glass are forming from a group of chemical elements, which their chemical interaction between each other affect groups of natural and chemical elements that each type of those glass are unique with it. The chemical composition of these species, as well as their thermal properties, is an important factor influencing the formation mechanisms. It therefore affects the achievement of the aesthetic and use requirements of the glass products formed from them, and the heat resulting from the flame torch has a significant impact on the formation processes, as well as on the final form of the product. Therefore, it is important to study these glass types' properties and the flame of the torch and the heat produced from it during the heat forming process.
And here comes the problem of research in the reduction of the glass production system with lampworking restructuring techniques due to the lack of sufficient information on the properties of glass and factors affecting lampworking glass during heat formation. The aim of the research is to identify the factors affecting the lampworking glass and to show the effect of heat on the glass product during the formation stages.
