Introduction: Eco friendly crystal glass is a type of crystal glass which is produced without using lead and barium. Both chemicals are important to increase the sparkling effects of the glass properties. However, the use of these materials will affect to human health. As a substitution, potassium and titanium have been added to the glass mixture. The replacement make the crystal glass quality is comparable to crystal glass containing lead and barium. Currently, the crystal glass mix is produced in the form of pellet which ease the handling and melting process.

Advantages: Environmental friendly, good refractive index

Commercial application: Crystal glass is desirable owing to its decorative properties and commonly used as tableware and decorative glassware.

Novelty: The crystal glass formulation without lead and barium but give higher refractive index.

Invention: Filing the Utility Innovation with IP number UI 2012004620.

Commercialisation: Ready to be commercialised.

Technology brief : Development of Glass-Ceramic Tile from Recycled Glass

Soda-lime glass (SLG) is the most common type of glass, usually in the form of sheet glass and glass containers. SLG is relatively inexpensive, chemically stable, and extremely workable. Hence, it is capable of being re-melted numerous times, it is ideal for glass recycling. SLG can be utilized effectively to form glass-ceramic materials for many purposes such as for tiling applications. In this aspect, SLG is mixed with colour pigment and clay binder and followed by sintering process at temperature around 700-800 °C to form dense body of glass-ceramic. The quality of glass-ceramic tile is determined by its high body strength and surface hardness, low water absorption and good chemical and stain resistance. By using this route process, two advantages are identified namely low production cost and the usage of waste material.
