Analysis of the Causes of Spontaneous Breakage of Tempered Glass
Spontaneous glass breakage refers to a phenomenon in which tempered glass may spontaneously shatter without any external force. This issue has become a safety concern due to the widespread use of tempered glass in daily life, particularly in locations frequently encountered by people, such as high-rise buildings, bathrooms, and glass doors.

The causes of spontaneous breakage in tempered glass can be broadly classified into external factors and internal factors, as detailed below:

How Can Tempered Glass Spontaneous Breakage Be Prevented?

The spontaneous breakage rate of tempered glass typically ranges from 0.3% to 3%. Although this probability is relatively low, it is essential to understand the preventive measures for tempered glass spontaneous breakage:



Reducing the Stress Level in Tempered Glass



Regular float glass may suffer from insufficient strength or thermal breakage but does not experience spontaneous breakage. This suggests that lowering the stress level in tempered glass can help reduce its spontaneous breakage rate.

Glass Pre-Processing Requirements Before Entering a Glass Tempering Furnace
To ensure optimal results, several important steps must be completed before glass is introduced into a glass tempering furnace. These include proper cleaning and inspection processes, as outlined below:

1. Thorough Cleaning of the Glass

Before tempering, glass must be thoroughly cleaned to remove dirt and debris. This includes residues from cutting, drilling, or edge grinding. If the glass is not cleaned properly or remains damp with water spots, these imperfections can result in surface defects after tempering, which will be impossible to correct.

2. Drying Process

After cleaning, ensure the glass is completely dry. Any water stains left on the surface can cause visible defects after tempering.

3. Final Inspection Before Tempering

Introduce a re-inspection step before the glass enters the tempering furnace. Damage sustained during earlier processes, such as scratches or chips, can significantly affect the quality of the tempered glass. This additional inspection ensures the quality of the raw glass and acts as a final checkpoint for defects missed during initial quality control.

The Fourth #LandGlass Tempering Furnace to Be Delivered to Transparent Design, #Romania, in Early 2025


LandGlass is proud to continue its partnership with Transparent Design, Romania's largest flat glass processor, in its commitment to delivering high-quality glass products. Since its founding in 2005, Transparent Design has been a leader in the industry, consistently investing in advanced technology to enhance production capabilities.


Between 2021 and 2024, Transparent Design selected three LandGlass UltraJet tempering furnaces to meet their growing production demands. In 2021, they installed the UltraJet A3260U, a machine capable of tempering glass sizes up to 6000 x 3300 mm with 5 to 19 mm thicknesses. This was followed by the installation of the UltraJet Plus Bottom SuperAir in May 2022, a great furnace designed to temper glass up to 5000 x 2400 mm with thicknesses between 3.2 and 19 mm, and a minimum size of 150 x 300 mm. By February 2024, the third furnace, the UltraJet LD-A3050U, was fully operational, boosting Transparent Design’s tempered glass output from 1100 sqm to 1600 sqm per 8-hour shift. This furnace can handle glass sizes up to 5000 x 3000 mm and thicknesses ranging from 5 to 19 mm, further solidifying its position as a leader in Romania’s glass market.


Excitingly, the fourth LandGlass glass tempering furnace is on its way to Transparent Design, expected to be delivered at the beginning of 2025. This cutting-edge glass tempering machine is designed to handle large-format tempered glass, up to 9000x3210 mm. It features advanced convex and concave bending technology, allowing for the production of glass that perfectly meets the sophisticated aesthetic and quality requirements of modern architecture, making it an excellent choice for high-end projects.


In addition, 2 automated bending modules would be added to existing tempering furnaces, significantly enhancing Transparent Design’s production capabilities. With this new equipment, Transparent Design will be able to offer tempered curved glass, covering a diverse range of bending radii (both concave and convex), thanks to modern, computer-controlled equipment. The large-size curved glass with complex bends can be used in applications such as interior partitions, structural facades, balustrades, refrigeration displays, products for the automotive industry, and more.


The glass tempering technology used in LandGlass tempering furnaces at Transparent Design complies with European standards EN 12150 and EN 1863, ensuring top-quality and safety. LandGlass is proud to support their ongoing growth and look forward to continuing our successful partnership.

Why Convection Heating is Needed in Automotive Glass Processing？

As automotive glass designs become more complex, achieving uniform heating during production has become a significant challenge. Modern windshields and sunroofs feature intricate shapes, larger screen-printed areas, and advanced coatings, all of which require precise heating to maintain optical quality. Traditional radiation heating often falls short, leading to issues like burn lines, optical distortions, and overbending.
