Glass for the Future glass for the future www.controlglass.com With the experience obtained in the last 20 years, Control Glass has suc- ceeded in gathering all the processes a glass processor of the 21st cen- tury should offer to the glass professionals. With the new plant in Platea (Teruel) for the production of curved laminated and tempered glass we have become one of the most polyvalent glass groups in Europe, being able to offer the widest range of processed products, with the capacity to combine different processes such as laminating, tempering, bending, double glazing or printed with ceramic inks. We have over 50.000 m2 between factories, warehouses and technical offices, distributed around all over Europe, enabling us to deliver our pro- ducts to any point of the world. All our glasses meet the high demands of the applicable European Norms and also the Technical Building Code, which through the European Directive “Products for Buildings” 89/106/CE imposes the marking and declaration of technical characteristics of buil- ding products permanently incorporated in the building site. The “Obligatory CE Marking” allows for the manufacture and sale of the products within the European Union and requires a satisfactory evaluation of the products in accor- dance with the corresponding harmonized norms and with the applicable certificate of conformity. You can request the obligatory CE Marking of the products that Control Glass manufac- tures and selles through their web site: www.controlglass.com On the other hand, Control Glass has proved its commitment through the quality of its products and its customer care by obtaining the voluntary product certification for APPLUS double glazing units for all its factory units, as well as the global voluntary cer- tification according to the Quality Assurance System ISO 9001-2008, supported by the British Standards Institution certifying authority. Technical Advice Three technical departments work closely with architects, façade glaziers and installers to find the perfect solution and the most adequate process, for either exterior or interior glazings. One of the technical departments totally dedicates itself to curved glass and another team dedicates itself to flat glass and its installation by means of hardware. The quality department co-ordinates both departments in issues related to certifications and the necessary tests for each case, as well as to the suitability of its application. New ideas are welcome in Control Glass, assisting us to stretch the limits of our creativity. In projects where the glazing has a structural role the technical department of the Control Glass offers the possibility to solve the problems in an integral manner by closely collaborating with the prescribers and co-ordinating all acting parties. The R & D department keeps us in a continuous spiral of innovation through its constant initiatives in the search of new processes. 06. Annealed curved glass 08.

Active.Lite® Annealed curved glass ATM at ING Direct Monumental Staircase, Paris Partition, Local Police, Teruel 06 Performance Centre of the Pozo de Nieve, Segovia Versatility and complex geometry Annealed curved glass is obtained through slow heating with high convection up to the sagging temperature of the flat glass sheet, which by means of a bending mould is curved to obtain any type of complex geometry. Thereafter the glass is slowly cooled (annealed). This technique offers a wide range of shapes such as double radius, flat and radius, conical shapes and even projects with spherical glass shapes. The versatility of this process also allows us to bend all types of glasses: tinted, patterned, thermo-shaped, Low-E, solar control, selective coatings and screen-printed. Furthermore it improves the optical quality compared to a curved tempered glass and for this reason it is more adequate for the production of laminated glass and double glazed insulating glass. • It allows large sizes Minimum radius according to glass thickness Thickness Radius Max. depth of bend • Low-E Glass, selective coatings or (mm) (mm) (mm) solar control glass A >10 300 600 • Better optical quality B 8 - 10 250 600 C 6 - 8 150 600 D 4 - 5 - 6 100 600 Maximum size 4.400 x 2.700 mm Most frequent shapes double curvature J-bend double J-bend conical half circle spherical 07 Cylindrically curved tempered glass Morocco Mall, Casablanca Novovisión Ophthalmology Clinic, Murcia Rey Juan Carlos de Móstoles Hospital, Madrid 08 Stairway of the Basílica del Pilar, Zaragoza Curved tempered glass is obtained through heating by convection, bending with automatic tools and subsequent fast cooling, which results in a considerable increase of mechanical strength and the possible breakage into small grains, thus making it into a safety glazing. Furthermore, we can produce semi-tempered glass and carry out the Heat Soak Test if the project demands it. We have three different formats for our cylindrical benders, with different radii and spans in order to offer the widest range of solutions to the market, for either industrial or architectural glazings. The high convection in these furnaces allows us to bend and temper high selectivity coated glasses and Low-E glasses, with emissivity values down to 0,03. The high mechanical strength obtained through tempering allows us to produce glass units with holes, indents and edgework. The precision of these bending furnaces enables us to carry out projects with curved tempered and laminated glazings with high quality edgework.

As the flat glass is heated to be thermally strengthened, 19 which takes a few minutes, there is an opportunity for performing a surface modification. We describe 20 the application of transparent and amorphous Al2O3 thin films during the thermal strengthening process. 21 Al2O3 was chosen due to the following desirable properties: increased surface mechanical properties 22 and increased chemical durability, the latter has not been investigated in the current paper. The residual 23 surface compressive stresses after performed strengthening of the coated glasses were quantified to 24 be in the range of 80-110 MPa. The Al2O3 content in the surface was measured using the Surface 25 Ablation Cell employed with Inductively Coupled Plasma Atomic Emission Spectroscopy and found to 26 be at least doubled at the surface and having an increased Al2O3 content at least 0.5 µm underneath 27 the glass surface.

In those ingredients, boron and silicon have high content: boron 12,5 – 13,5 %, silicon 78 – 80 %. SiO2 80 % B2O3 13 % Na2O 4 % Al2O3 2 % K2O 1 % Trade The feature of borosilicate glass 3.3 is that it has low thermal expansion coefficient, good thermal stability, chemical durability and electric property. Therefore, it’s chemical resistant, heat resistant and mechanical property is excellent. So borosilicate glass is also called heat resistance glass. Borosilicate glass 3.3 can be milled, drilled, grounded and toughened. Its low coefficient of thermal expansion, high thermal shock resistance and ability to work at temperatures up to 450 ° C for a long period of time, make this type of glass particularly suitable for use in stable temperature conditions. Is suitable for operation at low temperatures. This glass can withstand the temperature to about -196 °C (is suitable for use in contact with liquid nitrogen). During thawing ensure that the temperature difference does not exceed 100 K. In general is recommended for use down to - 70 °C. This glass is extremely resistant to water, alkalis, acids and organic substances.

    ARTICLE https://doi.org/10.1038/s41467-021-22595-1 OPEN Explosive fragmentation of Prince Rupert’s drops leads to well-defined fragment sizes ✉ Stefan Kooij 1 , Gerard van Dalen2, Jean-François Molinari 3 & Daniel Bonn1 Anyone who has ever broken a dish or a glass knows that the resulting fragments range from roughly the size of the object all the way down to indiscernibly small pieces: typical fragment size distributions of broken brittle materials follow a power law, and therefore lack a char- 1234567890():,; acteristic length scale. The origin of this power-law behavior is still unclear, especially why it is such an universal feature. Here we study the explosive fragmentation of glass Prince Rupert’s drops, and uncover a fundamentally different breakup mechanism. The Prince Rupert’s drops explode due to their large internal stresses resulting in an exponential frag- ment size distribution with a well-defined fragment size. We demonstrate that generically two distinct breakup processes exist, random and hierarchical, that allows us to fully explain why fragment size distributions are power-law in most cases but exponential in others. We show experimentally that one can even break the same material in different ways to obtain either random or hierarchical breakup, giving exponential and power-law distributed fragment sizes respectively. That a random breakup process leads to well-defined fragment sizes is surprising and is potentially useful to control fragmentation of brittle solids. 1 Van der Waals-Zeeman Institute, University of Amsterdam, Amsterdam, The Netherlands. 2 Unilever Research and Development Vlaardingen, Olivier van Noortlaan, Vlaardingen, The Netherlands.

The glass samples were cut into 130 x 30 x 4 mm and heated at varying temperature ranges of 570, 590, 610, 630 and 650oC respectively in a muffle furnace. The samples were then tempered by rapid ooling in a bath of oil and allowed to cool to room temperature. Micro graphical examination, hardness and flexural tests were carried out on the tempered glass samplesIJSER and result obtained shows that the internal structure of the tempered glass were better enhanced at temperature of 570oC, while the hardness value was also found to be better at this temperature. The hardness value records it lowest when the sample was heated to a temperature of 650oC while the result obtained from the flexural strength test shows that the bending strength of the tempered glass samples were reduced compared to the control sample.
