The real difference is the trademark and the company that owns the Pyrex name. When the kitchenware division was sold, the trademark was changed to lowercase pyrex and switched to low thermal-expansion soda-lime glass.

The scientific division of Pyrex has always used borosilicate glass [3]. In addition to quartz , sodium carbonate , and aluminium oxide traditionally used in glassmaking, boron is used in the manufacture of borosilicate glass.

Though more difficult to make than traditional glass due to the high melting temperature required, it is economical to produce. Its superior durability, chemical and heat resistance finds use in chemical laboratory equipment, cookware, lighting, and in certain kinds of windows.

Borosilicate glass is created by combining together and melting boric oxide , silica sand, soda ash , [4] and alumina.

Since borosilicate glass melts at a higher temperature than ordinary silicate glass , some new techniques were required for industrial production.

The manufacturing process depends on the product geometry and can be differentiated between different methods like floating, tube drawing , or moulding.

The common type of borosilicate glass used for laboratory glassware has a very low thermal expansion coefficient 3.

This reduces material stresses caused by temperature gradients, which makes borosilicate a more suitable type of glass for certain applications see below.

Fused quartzware is even better in this respect having one-fifteenth the thermal expansion of soda-lime glass ; however, the difficulty of working with fused quartz makes quartzware much more expensive, and borosilicate glass is a low-cost compromise.

While more resistant to thermal shock than other types of glass, borosilicate glass can still crack or shatter when subjected to rapid or uneven temperature variations.

The softening point temperature at which viscosity is approximately 10 7. Borosilicate glass is less dense about 2. Optically, borosilicate glasses are crown glasses with low dispersion Abbe numbers around 65 and relatively low refractive indices 1.

For the purposes of classification, borosilicate glass can be roughly arranged in the following groups, according to their oxide composition in mass fractions.

The amount of boric oxide affects the glass properties in a particular way. Hence we differentiate between the following subtypes.

High chemical durability and low thermal expansion 3. High-grade borosilicate flat glasses are used in a wide variety of industries, mainly for technical applications that require either good thermal resistance, excellent chemical durability, or high light transmission in combination with a pristine surface quality.

Other typical applications for different forms of borosilicate glass include glass tubing, glass piping , glass containers, etc. This is a subtype of slightly softer glasses, which have thermal expansions in the range 4.

Sealability to metals in the expansion range of tungsten and molybdenum and high electrical insulation are their most important features.

The increased B 2 O 3 content reduces the chemical resistance; in this respect, high-borate borosilicate glasses differ widely from non-alkaline-earth and alkaline-earth borosilicate glasses.

Borosilicate glass has a wide variety of uses ranging from cookware to lab equipment, as well as a component of high-quality products such as implantable medical devices and devices used in space exploration.

Virtually all modern laboratory glassware is made of borosilicate glass. It is widely used in this application due to its chemical and thermal resistance and good optical clarity, but the glass can react with sodium hydride upon heating to produce sodium borohydride , a common laboratory reducing agent.

Fused quartz is also found in some laboratory equipment when its higher melting point and transmission of UV are required e.

Additionally, borosilicate tubing is used as the feedstock for the production of parenteral drug packaging, such as vials and pre-filled syringes , as well as ampoules and dental cartridges.

The chemical resistance of borosilicate glass minimizes the migration of sodium ions from the glass matrix, thus making it well suited for injectable-drug applications.

Borosilicate is widely used in implantable medical devices such as prosthetic eyes, artificial hip joints, bone cements, dental composite materials white fillings [10] and even in breast implants.

Many implantable devices benefit from the unique advantages of borosilicate glass encapsulation. Applications include veterinary tracking devices , neurostimulators for the treatment of epilepsy, implantable drug pumps, cochlear implants, and physiological sensors.

During the mid-twentieth century, borosilicate glass tubing was used to pipe coolants often distilled water through high-power vacuum-tube —based electronic equipment, such as commercial broadcast transmitters.

Borosilicate glasses also have an application in the semiconductor industry in the development of microelectromechanical systems MEMS , as part of stacks of etched silicon wafers bonded to the etched borosilicate glass.

Glass cookware is another common usage. Borosilicate glass is used for measuring cups, featuring screen printed markings providing graduated measurements.

Borosilicate glass is sometimes used for high-quality beverage glassware. Borosilicate glass is thin and durable, microwave- and dishwasher-safe.

Many high-quality flashlights use borosilicate glass for the lens. This increases light transmittance through the lens compared to plastics and lower-quality glass.

Several types of high-intensity discharge HID lamps, such as mercury-vapor and metal-halide lamps , use borosilicate glass as the outer envelope material.

New lampworking techniques led to artistic applications such as contemporary glass marbles. The modern studio glass movement has responded to color.

Borosilicate is commonly used in the glassblowing form of lampworking and the artists create a range of products such as jewelry , kitchenware , sculpture , as well as for artistic glass smoking pipes.

Organic light-emitting diode for display and lighting purposes also uses borosilicate glass BK7. However, depending on the application, soda-lime glass substrates of similar thicknesses are also used in OLED fabrication.

Most astronomical reflecting telescope use glass mirror components made of borosilicate glass because of its low coefficient of thermal expansion. The optical glass most often used for making instrument lenses is Schott BK-7 or the equivalent from other makers , a very finely made borosilicate crown glass.

Other less costly borosilicate glasses, such as Schott B or the equivalent, are used to make " crown-glass " eyeglass lenses. Ordinary lower-cost borosilicate glass, like that used to make kitchenware and even reflecting telescope mirrors, cannot be used for high-quality lenses because of the striations and inclusions common to lower grades of this type of glass.

Glassblowers borrowed technology and techniques from welders. Borosilicate glass has become the material of choice for fused deposition modeling FDM , or fused filament fabrication FFF , build plates.

Its low coefficient of expansion makes borosilicate glass, when used in combination with resistance-heating plates and pads, an ideal material for the heated build platform onto which plastic materials are extruded one layer at a time.

The initial layer of build must be placed onto a substantially flat, heated surface to minimize shrinkage of some build materials ABS , polycarbonate , polyamide , etc.

Subsequently, following the build, the heating elements and plate are allowed to cool. The resulting residual stress formed when the plastic contracts as it cools, while the glass remains relatively dimensionally unchanged due to the low coefficient of thermal expansion, provides a convenient aid in removing the otherwise mechanically bonded plastic from the build plate.

In some cases the parts self-separate as the developed stresses overcome the adhesive bond of the build material to the coating material and underlying plate.

Aquarium heaters are sometimes made of borosilicate glass. Due to its high heat resistance, it can tolerate the significant temperature difference between the water and the nichrome heating element.

Specialty glass smoking pipes for cannabis and tobacco are made from borosilicate glass. The high heat resistance makes the pipes more durable. Some Harm Reduction organizations also give out borosilicate pipes intended for smoking crack cocaine , as the heat resistance prevents the glass from cracking, causing cuts and burns that can spread Hepatitis C.

Most premanufactured glass guitar slides are also made of borosilicate glass. Borosilicate is also a material of choice for evacuated-tube solar thermal technology , because of its high strength and heat resistance.

The thermal insulation tiles on the Space Shuttle were coated with a borosilicate glass. Borosilicate glasses are used for immobilisation and disposal of radioactive wastes.

In most countries high-level radioactive waste has been incorporated into alkali borosilicate or phosphate vitreous waste forms for many years, and vitrification is an established technology.

This characteristic has been used by industry for centuries. Borosilicate glass tubing is used in specialty TIG welding torch nozzles in place of standard alumina nozzles.

This allows a clear view of the arc in situations where visibility is limited. It was initially thought that borosilicate glass could not be formed into nanoparticles , since an unstable boron oxide precursor prevented successful forming of these shapes.

However, in a team of researchers from the Swiss Federal Institute of Technology at Lausanne were successful in forming borosilicate nanoparticles of to nanometers in diameter.

The researchers formed a gel of tetraethylorthosilicate and trimethoxyboroxine. When this gel is exposed to water under proper conditions, a dynamic reaction ensues which results in the nanoparticles.

Borosilicate or "boro", as it is often called is used extensively in the glassblowing process lampworking ; the glassworker uses a burner torch to melt and form glass, using a variety of metal and graphite tools to shape it.

Lampworking is used to make complex and custom scientific apparatus; most major universities have a lampworking shop to manufacture and repair their glassware.

For this kind of "scientific glassblowing", the specifications must be exact and the glassblower must be highly skilled and able to work with precision.

Lampworking is also done as art, and common items made include goblets, paper weights, pipes, pendants, compositions and figurines.

In , English metallurgist John Burton brought his hobby of hand-mixing metallic oxides into borosilicate glass to Los Angeles.

Burton began a glass workshop at Pepperdine College, with instructor Margaret Youd. A few of the students in the classes, including Suellen Fowler, discovered that a specific combination of oxides made a glass that would shift from amber to purples and blues, depending on the heat and flame atmosphere.

Fowler shared this combination with Paul Trautman, who formulated the first small-batch colored borosilicate recipes.

He then founded Northstar Glassworks in the mids, the first factory devoted solely to producing colored borosilicate glass rods and tubes for use by artists in the flame.
