Computer technology has achieved tremendous success regarding design and productivity requirements in various branches of science and arts, contributing to the development and progress of design and production systems in general. The field of glass jewelry is one of the important fields in which computer can play an influential role in the design and production.This role is evident through the possibility of using the computer in various stages of glass jewelry Design, even rendering and modeling. The uses of computer programs in that field are numerous and variable. This research tries to identify the most important of these programs and their impact on the design of glass jewelry produced by casting method, and hence the research problem which is the lack of use of the computer potentials in enriching the design system for glass jewelry produced by casting method The objective of the research is to develop a set of scientific and technical foundations to take full advantage of computer potentials as an added value to enrich the design process and develop non-stereotyped alternatives to the design of glass jewelry produced by casting. The research assumes that by using computer capabilities and analysis of glass design systems, the most important scientific and technical foundations for enriching the design system can be reached. The importance of this research is its contribution in the development of the field of glass jewelry industries and enriching the scientific library in the field of glass design using computer. The research is limited by the use of computer software (Rhino) for glass jewelry produced by casting method through analytical and experimental methodology. The research dealt with a number of axes which include showing the possibility of using the computer in glass jewelry industry, and laying down the basics for using the Rhino program in the design of glass jewelry produced by casting method through a series of experimental studies. The main research result is laying down scientific and technical foundations for using the Rhino program in the design of glass jewelry produced by casting method.

Computer technology has achieved tremendous success regarding design and productivity requirements in various branches of science and arts, contributing to the development and progress of design and production systems in general. The field of glass jewelry is one of the important fields in which computer can play an influential role in the design and production. In context of the updates that have emerged in the design and manufacturing programs, it is necessary to change the manufacturing or implementation methods to take full advantage of these programs potentials, especially in the field of glass jewelry such as building models, forming molds, forming the external structure of the product and shaping the surface appearance. The research problem was detected as the lack of use of CAM systems in solving the problems and applications of glass jewelry production. The objective of the research is to activate CAM systems in a methodological setting for the implementation of glass jewelry. The research hypothesizes that by activating the potential of the CAM systems, the foundations and considerations for implementation of the glass jewelry can be established with the aim of reaching a methodology for utilizing the CAM systems in their implementation. The research is importance is developing and enriching the field of implementation and manufacture of glass jewelry using computer systems. The research dealt with a number of axes which include the use of CAM systems in implementation of glass jewelry, aiming to a methodology for their implementation using CAM systems and producing some glass jewelry products in context of the proposed methodology for implementation

Refractories are characterized by their ability to withstand high temperatures that reach 2800°C, their ability to withstand sudden changes in temperature, resist mechanical shocks, due to the formation of glass at a temperature of 1050-1100°C, it is required that the molds manufactured from refractories withstand that temperature. This is in addition to the ability of the refractory material to show the fine details and the prominent and recessed sculptural surfaces (smooth - rough) in the glass product, and to achieve the uniqueness and excellence of the glass product.This is due to the requirements of refractory mold in its manufacture and assortment with manual blowing in terms of its ability to withstand pressures, non-fragmentation, thermal endurance that reaches (1500 - 1750°C), and a low rate of expansion and contraction that reaches ± 0.05 mm, as well as its flat smoothness, which is considered as a mirror of a model formation.Since the glass material is acidic, it requires that the components of the refractory composition of the mold be acidic or neutral as well. To prevent the adhesion with the glass components thus, some refractories were selected that enter into the work of refractory formulations that can achieve chemical and natural properties suitable in the manufacture of glass forming molds by manual blowing. (16) Refractory compositions were made, and the research reached to find new refractories that meet the requirements. Thus, it is recommended to use refractories for producing the prototype of the glass products which are characterized by aesthetic products.
