Introduction

Ultra clear glass is made of low iron content raw materials. So it is also known as low iron glass or super clear glass. Ultra clear glass bears extraordinary high light transmission. This benefits internal daylight propagation when the crystal clear glass is used for external cladding of constructions. Ordinary clear glass looks green versus ultra clear glass. Characteristics of high clarity ultra clear glass are as good as ordinary clear float glass. They include physical, mechanical and optical properties. Like ordinary clear gloat glass, low iron glass could be further processed such as grinding, drilling, tempering, laminating, mirroring, coating, printing, etc.
