Low Iron Tempered Glass

 

What is Ultra-clear (Low-Iron) Tempered Glass?

 

Ultra-clear tempered glass, also known as low-iron tempered glass, is a premium architectural safety glass produced with extremely low iron content (Fe₂O₃ ≤ 0.015%). This ultra-low iron level significantly reduces the natural greenish tint found in regular tempered glass, delivering higher visible light transmittance, crystal-clear clarity, and true color rendering.

 

Manufactured through advanced thermal tempering, ultra-clear tempered glass from MIGO GLASS provides 4–5 times the strength of standard annealed glass while offering exceptional optical performance-making it the preferred choice for luxury architecture, modern interiors, display cases, and high-end commercial environments.

FAQ

Q1: How to judge the quality of float glass?

Flatness, transparency, colorless, impurities, bubbles, etc.

 

Q2: How to reduce the self-implosion?

The high-quality float method is used for hot-dip treatment, edge treatment, and proper

stress intensity. Pay attention to avoid side collision of glass during installation.

 

Q3: Scope of use of tempered glass?

Safety is not involved in some parts of the building, but it is necessary to install toughened

glass to improve the compressive strength and explosion-proof capacity, and not to endanger

the safety of the person.

 

Q4: When tempered glass is broken, is the grain smaller the better?

No, the smaller the particle, the easier it is to explode.

 

Q5: Can tempered glass and heat-strengthened glass be made into laminated glass?

Can't. The national standard stipulates: the glass that stresses the difference cannot make laminated glass, because in the use process, the pressure that two pieces of glass bear is different.
