Innovation History
The founder of SCHOTT, Otto Schott, is considered to be the inventor of specialty glass and the trailblazer of the specialty glass industry. With his groundbreaking glass developments, he embedded a pioneering spirit deep in the SCHOTT DNA more than 140 years ago. Since then, SCHOTT pioneers have been constantly opening up new markets and applications with increasingly exciting innovations.
2024
A significant milestone on the way to climate-neutral production was achieved in 2024: After successfully testing glass production with 100 percent hydrogen on a laboratory scale in 2023, SCHOTT completed the much anticipated industrial-scale application. This pioneering achievement marks a significant milestone in making the energy-intense production of specialty glass more sustainable, even on a larger, mass-manufacturing scale.
For three days, SCHOTT was capable of melting optical glass in a furnace using the new technology for the first time – exclusively heated by hydrogen, completely free of natural gas.
2023
Protecting mRNA vaccines with the world’s first prefillable syringes for deep-cold storage
Sensitive drug formulations must be stored at deep-cold temperatures approaching -100°C to ensure drug stability. In 2023, SCHOTT Pharma introduced prefillable polymer syringes specifically designed for drug applications that need to be stored and transported in frozen conditions. This marked the first time that deep-cold medications such as mRNA, cell, and gene therapies, could be introduced to the market using prefillable syringes.
2020
Setting the most ambitious climate goal in the industry
As a global specialty glass manufacturer, SCHOTT is part of an energy-intensive industry with a large CO2 footprint. Through technology change, improved energy efficiency, covering 100 percent of its electricity requirements worldwide with renewable energies, and offsetting any remaining climate-damaging emissions by investing in certified climate protection projects – SCHOTT set out in 2020 to undertake the massive upheaval in glass production needed to meet this challenge.
2019
Microarrays for lab-on-a-chip technology
Pioneering the use of ultrashort-pulse laser cutting and glass fusion bonding, SCHOTT developed a glass structuring process that pushed the possibilities of microfluidic structures, often called a "lab on a chip," used in diagnostics and life sciences. Allowing for such complex geometries, SCHOTT paved the way for lab-on-a-chip technology that could enable efficient, cost-effective, and impactful healthcare solutions.
2018
High-index glass wafers and waveguides for augmented and mixed reality
With a rich history in advanced optics, SCHOTT had an early understanding of where the AR market could go, and was uniquely positioned to evolve its high-index optical glass products into the next breakthrough for AR devices. That's why the company developed SCHOTT RealView® high-index glass wafers that enable unmatched immersive user experiences through lighter smart glasses coupled with stunning image quality.
2016
Scratch-resistant coatings for improved cooktop durability
After CERAN® glass-ceramic cooktops revolutionized kitchens in 1971, SCHOTT CERAN Miradur® emerged in 2016 with miraculous durability. It combined the impressive thermal, mechanical, and chemical properties of CERAN® glass-ceramic with a patented scratch-resistant coating. Capable of handling the everyday stresses of kitchen life, Miradur® marked a seemingly impossible breakthrough in material design.
2013
Ultra-thin glass - the thinnest glass in the world
As early as the late 1980s, SCHOTT succeeded in manufacturing thin glasses with thicknesses of 0.035 to 0.055 millimeters for applications in electronics and medicine.
Then, in 2013, the company launched an ultra-thin glass with a thickness of just 0.025 millimeters. It is the thinnest glass in the world, thinner than a human hair, yet extremely stable and flexible. With these properties, it offers completely new application possibilities, for example for smartphones and tablets with foldable displays.
2002
Expansion of materials competence with polymer
Starting in 2002, SCHOTT expanded its material competence with a plastics innovation. SCHOTT was the first company in the world to manufacture prefillable syringes from the high-tech polymer COC (cyclo-olefin copolymer).
The SCHOTT TOPAC® polymer syringes are break-resistant and lightweight, yet as transparent as glass, and also have good barrier properties.
They are used for the administration of sensitive biotech drugs or highly-viscous pharmaceuticals, as well as in applications where glass syringes are less advantageous due to their fragility, for example in emergency medicine.
With a broad portfolio of glass syringes and polymer syringes, SCHOTT Pharma now covers all requirements from a single source.
1971
CERAN®glass-ceramics - revolution in the kitchen
In 1971, the household appliance manufacturer Imperial presented a stove with a SCHOTT CERAN® glass-ceramic cooktop surface for the first time. In 1973, SCHOTT started series production of this innovative cooktop.
With CERAN®, SCHOTT brought about a revolution in the kitchen. Cooking on conventional iron plates was now out; the cooking experience on a flat glass-ceramic surface became now state of the art. It combined much easier handling and care with energy savings and attractive design. CERAN® quickly became the global standard for glass-ceramic cooktop panels.
To date, 50 years after its market launch, SCHOTT has sold 200 million units.
1968
ZERODUR® glass-ceramics for the world's largest telescopes
In the 1960s, researchers at SCHOTT began the development of glass-ceramic as a new glass family. With its extremely low thermal expansion, in 1968, ZERODUR® ushered in a new era of telescope mirror substrates and quickly became the quality standard. The largest mirror substrate of the first order series was used in the 3.5-meter telescope in the Calar Alto Observatory in Spain.
In 1991, SCHOTT began manufacturing mirror substrates in the eight-meter class using a newly developed centrifugal casting process. Four of them are used in the Very Large Telescope (VLT) of the European Southern Observatory (ESO) in Chile.
The ESO also relies on ZERODUR® for its Extremely Large Telescope (ELT). With a diameter of 39 meters, the main mirror will be assembled from around 800 hexagonal ZERODUR® elements. When the ELT goes into operation in 2025, it will be mankind’s largest and most powerful tool for looking at the universe.
1939
Glass-to-metal seals for electronics
Developed in 1939, hermetic glass-to-metal seals provided reliable, long-term protection for the emerging electronics industry. The first area of application was capacitors for aircraft radios, while the vacuum-tight fusion of glass with metal is now used for the insulated feedthroughs of electrical conductors in hermetically sealed housings. Since 2001, ceramic-to-metal seals have been a key part of SCHOTT’s Electronic Packaging portfolio for electronics and high-speed data transmission.
1887
Borosilicate glass for technical applications
In 1887, Otto Schott began to develop glasses for technical applications. Using boric acid, he invented borosilicate glass, which had three very special properties: extraordinary resistance to heat, strong resistance to chemicals, and exceptional resistance to abrupt changes in temperature.
The first application of borosilicate glass was in technical thermometers (from 1891), which enabled temperature measurements up to 500 ºC for the first time. From 1893, laboratory glassware made using borosilicate glass catalyzed enormous progress in global science, while, from 1895, borosilicate glass lamp cylinders helped gas incandescent lighting technology to achieve a breakthrough. And from 1911, FIOLAX® borosilicate glass tubes became the standard for glass packaging in the pharmaceutical industry.
1884
Optical glasses for premium microscopes
In the early days of the company, Otto Schott focused on developing optical glasses, and is the first person to develop glasses with precisely defined optical properties such as light refraction and color dispersion. These new glasses enabled Carl Zeiss and Ernst Abbe to build the best microscopes in the world in their optical workshop.
Otto Schott also enabled further exploration of the universe. In 1894, he began producing optical disks with diameters up to 140 cm for refracting telescopes.
