Nowadays, the intricate artworks that are blown are good enough to blow your mind! Yes, we are talking about glassblowing. It is by definition termed as a glass-forming technique that involves inflating molten glass into a bubble with the aid of a blowpipe or a blow tube. Glassblowing, since ancient times, has been known as
What is Quartz? Quartz is a term used to describe many different compact forms of SiO2. As one of the second most common and varied minerals on earth, its abundant and can be found in crystalline form, naturally occurring, in many colors that produce different types of gemstones. What is Fused Quartz/Fused Silica? Fused quartz and fused silica is
Early History of Glass Natural glass has existed since the beginnings of time, formed when certain types of rocks melt as a result of high-temperature phenomena such as volcanic eruptions, lightning strikes or the impact of meteorites, and then cool and solidify rapidly. Stone-age man is believed to have used cutting tools made of obsidian
While experienced glassblowers can manually tool and grind their own glass joints and stopcocks, the time and effort required for these procedures is significant. As a result, most scientific glassblowers’ systems nowadays are made up of mass-produced components. With a few exceptions, industry established standards allow interchangeable connections regardless of manufacturer. The joints and stopcocks
A beaker is a cylindrical container used to store, mix and heat liquids in laboratories. Most are made of glass, but other non-corrosive materials, such as metal and heat-resistant plastic, are also used. Beakers usually have a flat bottoms and a lip around the top. They range in size from one millimeter to multi-liter. Bunsen
Both graduated cylinders and beakers are pieces of laboratory glassware that have a specific function. Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. Beakers are better for stirring and mixing liquids. Beaker A beaker is a simple laboratory piece of glassware that resembles a coffee mug without the handle. On its
During the course of history, human ingenuity and rise of technology enabled our ancestors to conquer the ability to create glass some 3 thousand years ago. Even though our modern technology enables us to create glass in much larger quantities, the initial recipe and ingredients that were perfected in Ancient Egypt, Rome and Persia remains
Properties of Fused Quartz Properties [English, Metric, International System of Units (SI) Value] Trace Impurities Pressure Calculations Fused Quartz Proper Usage Guidelines Silica is found almost everywhere in nature, it represents almost 1/3 the mass of the earth’s crust. Vitreous Silica is the generic term used to describe all types of silica glass, with manufacturers
Now you see it, now you don’t. Glass is a bit of a riddle. It’s hard enough to protect us, but it shatters with incredible ease. It’s made from opaque sand, yet it’s completely transparent. And, perhaps most surprisingly of all, it behaves like a solid material… but it’s also a sort of weird liquid
Material hardness is commonly understood as resistance to scratching or abrasion. However, different tests are used to measure different aspects of material hardness in accordance with the mechanical properties under investigation. Moreover, tests are conducted under varying experimental conditions and data analysis methods. Consequently, no direct relationship exists between the results of different hardness tests.
