You may be curious about what flat glass is and what it entails. Now, what is flat glass?
Flat glass is a highly versatile material that can be utilized in many applications because of its various thickness options.
Now, let’s dive into the details. Flat glass is composed of a blend of solid glass and molten tin.
This unique amalgamation gives it several distinctive characteristics. It possesses density and durability, yet surprisingly delicate in nature.
How Is Float Glass Made?
Let’s take a closer look at the fascinating process of how float glass is made in a flat glass company.
Stage 1: Melting and Refining
In glassmaking, there is a term called “batch,” which refers to a carefully prepared mixture of fine-grained ingredients.
This batch is meticulously crafted to ensure its quality and ideal composition.
Once prepared, it is poured onto a surface of molten glass in a location known as the “melter.” This is where temperatures reach an intense 1,500°C.
Inside the melter, several processes occur simultaneously. The intense heat guides the melting, refining, and homogenizing of materials.
This intricate process can last up to 50 hours, producing glass at a scorching temperature of 1,100°C.
The resulting glass is exceptional because it lacks imperfections such as inclusions and bubbles, with a smooth and flawless finish.
Stage 2: Float Bath
Next, the molten glass flows smoothly over a spout onto a polished surface of liquid tin. Starting at an intense temperature of 1,100°C, it elegantly emerges from the “float bath” as a solid ribbon.
This ribbon will be later used to make different flat glass types and is cooled to 600°C.
( Note:The primary concept of float glass has remained the same since the 1950s, but some changes are evident. Originally available only in a standard thickness of 6.8 mm, float glass now comes in a wide range of options, from super thin to a sturdy 25 mm.)
Stage 3: Coating
Advanced high-temperature technology in a flat glass company allows for coatings that can change the optical properties of the glass.
An impressive technique known as “chemical vapor deposition” (CVD) can apply coatings less than a micron thick.
These thin coatings can reflect both visible and infrared wavelengths, enhancing the versatility of the glass.
Stage 4: Annealing
Despite its calm formation process, float glass accumulates stress as it cools. If the stress becomes too much, the glass is at risk of cracking under pressure.
To prevent this from happening, the glass ribbon undergoes a heat treatment process inside a long furnace called a “lehr.”
This precise control ensures the glass remains in optimal condition throughout the manufacturing process.
Stage 5: Inspection
Thorough inspections are conducted at every stage of the production process to ensure its superior quality.
Automated inspection steps in to catch even the smallest imperfections that may go unnoticed.
This step is crucial to detect any flaws that would escape even the most keen human eye before taking it to the flat glass market.
Stage 6: Cutting to Order
Float glass is not a one-size-fits-all product; it is customized to meet different requirements. Imagine diamond-studded wheels carefully trimming any stressed edges and precisely cutting the glass to the specific size requested by customers.
And that concludes the fascinating process of manufacturing float glass.
It’s a perfect harmony of science and art, combining precision and innovation to produce a material that surrounds us in our everyday routines.
Different flat glass types
Next, let’s delve into the various types of flat glass available, each possessing its remarkable characteristics!
Float Glass
Float glass, the most prevalent and extensively utilized form of flat glass, is produced by floating molten glass on a bed of molten tin. This method creates a perfectly flat surface, free from any distortion. Float glass is recognized for its exceptional clarity, transparency, and consistent thickness.
Gorilla glass
Gorilla Glass is a brand of chemically strengthened glass developed by Corning Incorporated, known for its impressive durability and resilience. It can be up to 4 times more scratch-resistant than regular glass and withstand the impact of a 1-meter fall onto a hard surface. Despite its toughness, it maintains a thin profile, allowing manufacturers to create sleek and lightweight device designs.
Quartz Glass
Also known as silica glass, it is a special type of flat glass that is made primarily from high-purity silicon dioxide (quartz). Quartz glass has excellent heat resistance and chemical stability, so it is often used in high-temperature or corrosive environments.
Borosilicate Glass
A glass with boric acid and silicic acid as its main components, it has excellent heat resistance and chemical stability. This type of glass is famous for its low coefficient of thermal expansion, which allows it to maintain a stable shape at high temperatures and is not prone to breakage.
Tempered Glass
Tempered glass is a type of glass that undergoes special treatment to become highly durable and resistant to shattering.
Instead of breaking into sharp and dangerous fragments, tempered glass crumbles into small, harmless pieces.
This makes it an ideal choice for applications such as car windows, shower doors, and glass railings.
Laminated Glass
It comprises multiple layers with a sturdy, transparent plastic interlayer sandwiched in between.
This type of glass is highly effective for enhancing security, reducing noise, and protecting against harmful UV rays.
You can commonly find laminated glass used in banks, storefronts, and even as windshields for cars.
What is the difference between flat glass and float glass
Let’s clarify the confusion surrounding glass terminologies – flat glass vs float glass. You might have come across phrases like “flat glass” and “float glass.” Now, let’s delve into the details to understand the difference between these two types of glass.
Flat glass is like the experienced veteran of the glass industry.
Made in furnaces using sand and organic materials, it’s the top choice for a wide range of applications, including windows, walls, doors, and tables.
One of the remarkable qualities of this material is its versatility. It can be effortlessly shaped, polished, tempered, or even transformed with various textures and colors. And when it comes to refining and sculpting, it’s a breeze.
Now let’s talk about float glass. While it may bear a resemblance, it undergoes a distinct manufacturing process and boasts some remarkable quality features.
To begin with, raw materials are carefully blended and heated before embarking on a serene venture through a “float bath”.
As the mixture cools down, it gracefully transforms into a sleek ribbon-like form.
The special quality of float glass lies in its surface. Float glass is exceptionally smooth, thick, and even. The beauty of float glass is all about achieving that perfect, flawless finish.
Let’s break it down: flat glass is the wider category that encompasses float glass. It’s similar to how “cars” includes “sports cars.” However, in the glass industry, we like to make a distinction because float glass offers an added level of quality and smoothness.
What is flat glass used for
Glass doors
Flat glass glass doors can transform a regular entrance into a visually appealing focal point.
Beyond aesthetics, they also provide added security by allowing you to see who is on the other side before opening up. Additionally, glass doors seamlessly connect indoor and outdoor spaces, giving your home an expanded and open feel.
