I am looking for a source for reasonably priced “float Glass”. I tried my local glass dealers and they want $48.00 for a 1/2" thick piece 4 inches by twelve. Garret Wade is about $29.00 for an 11" piece. I need 3 or 4 pieces 12"x 4" or more–1/2 thick. Does anyone have any sources for this glass at reasonable prices? I know that Float Glass requires special manufacturing techniques. I plan to use this for a Scary Sharp sharpening system. I appreciate all of your assistance.

Glass packaging is one of the most popular choices for many different industries. Glass is scientifically proven to be chemically stable and non-reactive, which is why it holds a Generally Recognized as Safe (GRAS) status from the USA Food and Drug Administration.
Clear glass jars and colored bottles are commonly used in cosmetics, pharmaceuticals, and in the food and beverage industry. Consumers typically notice them because of their aesthetic quality. However, the truth is that glass containers offer more than just nice looks--and the businesses that use them know it.
In this article, we'll delve deeper into the bigger benefit of using glass jars: visible and ultraviolet light protection. We'll also discover how different types of containers, particularly clear and colored glass jars, differ in terms of their protective qualities, and how this knowledge can guide you in choosing the best containers for your business.
Additionally, we'll answer some of the common questions about glass jars: How are they made? What makes them clear or colored? Which glass containers are the best?
Let's start with a little bit of history. Humans have used naturally occurring glass, particularly obsidian or volcanic glass, since the Early Stone Age. Historical accounts say that people used glassy rocks to make sharp cutting and scraping tools. Around 2500 BC, people started using small pieces of obsidian as beads, bangles, or jewelry. It wasn't until centuries later when people discovered that glass could be made and molded into useful things like tableware and vessels or containers.
Some historians say that human-made glass was first discovered in Syria when a group of natron merchants got shipwrecked. Natron is a naturally occurring material that results from the combination of sodium carbonate decahydrate, sodium bicarbonate, and little amounts of sodium chloride and sodium sulfate. Natron has been used as a cleaning product for thousands of years, which is why it was a profitable product back in the day.
As stories tell it, the shipwrecked merchants used lumps of natron to mount their pots and cook food. As they cooked, the fire and the combination of natron and the sand below it produced molten glass, leading to the discovery of human-made glass.
Later on, glassmaking spread throughout different areas, including Egypt, Greece, and Rome. Soda, lime, and silica became the widely used materials to make glass, and glass vessels and bottles became common in many civilizations. However, glassmaking did not become as prominent, mainly because it was a difficult and painstaking craft to engage in.
However, one of the most important glassmaking innovations happened when the glass blowing technique was invented. With the use of an iron tube, glassmakers were able to make glass vessels with a more consistent structure. An iron tube is made with a mouthpiece on one end and a knob that holds the glass on the other. Glass blowing also enabled glassmakers to produce more glass bottles, jars, and other glass products within a shorter period of time.
However, glass blowing was still inefficient, especially in the face of an increasing demand for bottles and glass apothecary jars. This led inventors to come up with better ways to make glass--ways that will improve both the process and the output of glassmaking.
In 1903, an American inventor, Michael Owens, designed an automatic glass forming machine that can mass-produce glass bottles. In 1915, another inventor named Karl Peiler made an even more efficient machine called the "gob feeder." This machine had better temperature control, resulting in an improved mold of glass containers. Then, in 1925, Henry Ingle further improved the design by creating individual section feeders. This made glass production much more efficient, and many glass manufacturers still use this technology today.
What's more, people also found better ways to seal glass jars. The common seal that people used was made of wax, but clear glass jars with locking lids soon became common. Later on, various other types of caps and lids were invented, including corks, plastic lids, aluminum lids, lids with mist sprays, push pumps, and many more.
Because of these inventions that made the mass production of glass easier and more efficient, cheap glass jars are now easy to find. However, glass blowing hasn't left the scene. Today, glass blowers are considered as artisans who design skillfully craft glasses that no machine can make. Meanwhile, for businesses that need colored or clear glass jars wholesale, they can easily find suppliers who can provide machine-made glass containers.
The earliest glass containers were neither clear nor purposely colored. Instead, they were naturally stained--even had bubbles, sometimes--because of impurities in the materials used to make them.
It was during the Middle Ages when Venetians discovered that pyrolusite, a kind of manganese mineral, can eliminate materials that colored a glass melt. Pyrolusite back then was considered as the soap for glassmakers.
Later on, more discoveries were made, particularly coloring techniques to make glass more decorative. German chemist Johann Kunckel, for example, discovered that adding gold chloride resulted in a ruby-red colored glass.
Today, clear glass jars have become easier to make with the availability of pure materials and decolorizers. Glassmakers have also learned to use different additives to colorize glass. For example:
Indeed, businesses and individuals have gained a wide variety to choose from when it comes to glass containers. This choice usually boils down to aesthetics and personal preference. However, for products that have unpleasant reactions to light exposure, colored glass jars can give them the benefit that no clear glass jars can. Colored glass jars can offer different levels of light protection, and some of them can protect even against invisible light, particularly ultraviolet light.

The color of a glass container can indicate what kinds of light can be reflected and what types pass through the surface of that glass. Clear glass permits all types all light to pass through, blue glass reflects blue light and permits other types, red glass reflects red light and lets in others, and so on. These types of glass make good containers, but the light protection they provide goes from minimal to zero.
Also, aside from visible light, UV light is another important concern of product manufacturers and retailers. Different types of UV light can bring beneficial and harmful effects, which is why UV protection is often necessary for some product packaging.
Word of caution: not all glass containers that claim to block UV are true to their claim. As such, it's important to be cautious and trust only glass containers made by trusted glassmakers and delivered by reliable suppliers. Researching and reading reviews are great ways to avoid fake products.
In the same way that prolonged sun exposure can cause serious skin problems in humans, exposure to UV light can also cause problems in products. This is a serious matter for businesses, especially because the wrong choice of container can deteriorate the quality of their goods and the public's trust of their brand.
While not all products are light-sensitive, those that are will degrade easily when exposed to UV light, particularly UVb and UVc light. Because of this, some glass containers are designed to offer UV protection. UV protection helps in maintaining the quality of light-sensitive products, thereby prolonging their effectiveness and their shelf life.
Products that are sensitive to light include food items, medicines, beer and wine, and milk. Some beauty products are also sensitive and can lose their effectiveness when left unprotected.
When talking about UV light, it's important to understand that UV offers both harmful and healthful effects. In the case of certain products, harmful UV rays can speed up the rate of oxidation and degradation and greatly compromise the integrity of products. On the other hand, healthful UV light can act as a natural preservative. This type of UV light can fight microbial growth and keep products fresh even after days, months, or even years in storage.
This microbe-fighting quality is especially useful for products that are consumed slowly. Although the product's container will be opened every once in a while, there will be lower risks of contamination as the permitted UV light can take care of most contaminants.
Because of their protective qualities, UV glass containers can be used in a variety of ways. They're usually available in a wide variety of sizes, which should help a person determine what they can store in the glass.
The popular uses of UV glass containers include storing personal care products, herbs and spices, cooking condiments, essential oils, medicines, beverages, and many more.
As we've established previously, clear glass jars provide no light protection at all. As for some colored jars like cobalt blue glass jars, green jars, and red jars, they can filter certain types of visible light but not invisible light like UV rays.
Amber glass jars are some of the most affordable containers that can block all types of UV light. They are commonly used in storing medicines, wine, and beer. However, they also block light types that could be beneficial for products. As such, amber glass jars are good options but certainly aren't the best.
