Why Eliterglass heat soaked glass is not recommended?

As we know, the Nis inside glass will cause tempered glass self explosion after installation.

So many glass manufacturers recommend a heat soaking process after tempering to decrease the self breakage rate.

Heat soaking glass is finished by heat soaking furnace, take the after tempered glass into the furnace, heating up to 300℃, keeping the temperature for 2 hours and then decreasing the temperature.

The Nis inside glass will transfer and expand many times which can cause glass breakage, after heat soaking, the glass breakage rate can decrease much.

But how much final breakage ratio, nobody knows…

Why do we do not recommend the heat-soaked glass, let’s see.

1. Heat-soaked glass has no apparent difference from normal tempered glass.

The heat soaking process is not a process that can change glass appearance, and there are even no machines or tools to detect if the glass is heat soaked or not.

For clients, at least 10% increased costs on glass purchasing.

Many glass processors charged high heat soaking processes but don’t actually do the process.

They’ll offer false heat soaking test reports and don’t care about the result.

2. There are many alternative methods to avoid glass self breakage.

1) Heat-strengthened glass.
Compared with tempered glass,heat-strengthened glass won’t self breakage, and even if the glass is broken, the glass will keep the integrity

2) Use low iron glass.
Compared with normal clear glass, tempered low iron glass contains much less Nis and a much lower possibility of breakage, the low iron glass will also offer a more elegant appearance.

Anyway, please don’t use poor quality glass raw materials for your order, small float glass manufacturers’ products are not reliable and high possibility of breakage.
