Laboratory of glass, porcelain, ceramic and tableware

 physical and chemical characteristics and properties of these products. In ParsLian arvand company, there is a special department for the laboratory of porcelain and ceramic dishes and such goods, the technical knowledge and equipment necessary to perform the tests described in the texts of the national standards of Iran or other international standards. Glass and ceramic containers are placed in the same category due to the common mineral origin of the raw materials, and the methods of testing and checking their characteristics have many similarities.  
Glass or ceramic containers for dining, glass containers for packaging, crystal containers, opal, etc., each has a specific use, and for this reason, their quality requirements and properties are different. To maintain the quality levels of these products, manufacturers and quality control centers need accurate laboratory results to determine the exact limits of compounds, properties, functions, chemical and physical characteristics, and other criteria that influence their use. The clarity of technical and quality limits in the international marketing of these products and the formation of a precise relationship with the consumers of these products is very effective.  
Among the most important laboratory services of ceramic, glass, etc., we can mention the following:

  • Explaining the chemical and physical characteristics of each product separately. (Glass containers for eating, glass containers for making bottles and packaging, etc.)
  • Thermal analysis of tested containers to control raw materials (determining linear expansion, average thermal expansion coefficient, etc.)
  • Alkalinity resistance of porcelain, earthenware, glass and…
  • Determining the resistance of ceramic decorations
  • Determination of resistance to solutions
  • Determination of resistance and safety against gas stove waves
  • And…

During the study of the behavior of traditional or modern glass or ceramic materials, safety problems may always occur due to various reasons (including the high percentage of natural or artificial raw materials or problems in production processes), and this issue is one of the other reasons that emphasize the importance of standard principles. and glassware laboratories emphasizes.
