MIRONA® semi-transparent mirrored glass is made with SCHOTT’s proprietary sol-gel dipping technique, making it chemically stable, able to handle bumps and abrasions, and simple to maintain. With a range of processing options, from thermal toughening to lamination, MIRONA® can be customized to your requirements.

Tough, beautiful and easy to maintain

Stabilizing process

MIRONA® is produced using the quality-enhancing sol-gel dipping method. The glass is plunged into metal oxide solutions and the metal oxide coating layers are burned in at 450°C to 500°C. These layers are much purer and mechanically and chemically more stable than glass processed with conventional PVD techniques.

Durable for longer

MIRONA® is a highly advanced glass but its sophistication is matched by its robust constitution. The glass possesses high levels of resistance to chemicals and abrasions compared to mirrored float glass, and offers a long service life.

Toughening treatment

MIRONA® can be made even stronger by a choice of treatments. For example, it can be thermally toughened compared to mirrored float glass and processed into laminated safety glass.

Easy maintenance

It’s simple to maintain that MIRONA® sparkle. MIRONA® is much easier to clean than other similar glass on the market – just wipe using any regular glass-cleaning agent or towel moistened with a 1:1 mixture of denatured alcohol and water.
Product Range

The MIRONA® collection of semi-transparent mirrored glass is incredibly versatile. From MIRONA® Beamsplitter for high-resolution displays to MIRONA® High-Reflective Grey for a higher contrast, the innovative series provides a range of qualities for a variety of applications.


MIRONA® Standard

This extra-clear, low-iron float glass with optical interference coating on both sides offers defined reflection (34%) and transmission.


MIRONA® High-Reflective

An enhanced version of MIRONA® Standard for when higher mirroring is required, this has a high-reflective optical interference coating that offers 55% reflection.


MIRONA® Beamsplitter

MIRONA® Beamsplitter is an extra-clear, low-iron glass with an anti-reflective coating on one side and a high-reflective coating on the other for defined 36% reflection and transmission. Specially developed for high-resolution displays, the result is almost no irritating double reflection.


MIRONA® High-Reflective Grey

This grey float glass has a high-reflective coating on both sides and absorbs more light, so providing a darker background and therefore a higher contrast.


MIRONA® High-Reflective One Side Coated

Coated on just one side to produce MIRONA® Beamsplitter as a laminated safety glass.



MIRONA® is available in a number of dimensions and thicknesses:

Standard sheet dimension net (min)

  • 1,770 x 1,220 mm
  • 3,180 x 1,700 mm

Standard thickness*

  • 4 mm
  • 6 mm


* other thicknesses upon request

How it Works


The combination of two functions that traditionally juxtapose one another – reflection and transmission – is made possible by the special Sol-Gel-Dipping procedure that SCHOTT has developed: The glass is initially dipped in various metal-oxide solutions and then subsequently burned together, producing a striking effect. When the space behind the glass is dark, SCHOTT MIRONA® is an elegant mirror, but when lit, the light transforms it into a transparent window. 

The strength of the light and the ratio between the light sources both behind and in front of the pane determine the ultimate functionality of the glass.


Reflection: the viewer sees their mirror image.

Where is the strongest light source?

In front of the glass, MIRONA® is an elegant mirror, despite just 34% reflection. But behind the glass, MIRONA® opens up an additional layer for imagery, products and information.

Thermal Toughening

Glass of 3 mm thickness or more has the option of undergoing thermal toughening. This results in a 3-4 times more mechanical and thermal strength compared to non-toughened glass.

 Thermal toughening


Chemical Toughening

Glass of less than 3 mm can undergo chemical toughening. This process also creates surface compressive pressures but through ion exchange in a bath of molten salt.

Chemical toughening 


Screen Printing

Screen printing is used for customer-specific motifs, passe-partouts, logos, and more. Ceramic colors are suitable for thermal toughening, while organic colors are suitable for chemical toughening.


Screen printing 



Lamination involves the bonding of two or more glass plates in a vacuum using an adhesive layer.




General Introduction

1. What are the main features of SCHOTT MIRONA®?

  • SCHOTT MIRONA® magically transforms itself from a mirror to a transparent window. A unique combination of reflection and transmittance enables an ingenious presentation of space and objects.
  • Available on various types of materials (e.g. on the basis of extra-clear, low-iron float glass or grey glass).
  • Available in five unique coatings. Mirroring intensity varies depending on the degree of reflection:
    • MIRONA® Standard
    • MIRONA® Beamsplitter
    • MIRONA® High Reflective
    • MIRONA® High Reflective Grey
    • MIRONA® High Reflective One side coated
  • MIRONA®Beamsplitter is specially designed for high-resolution displays.
  • The coating is highly chemically resistant.
  • Transforms from a transparent display to a mirror without any electricity.
  • Maintenance-free!
  • Easier to clean than competitive products. 
  • Diverse processing options (e.g. laminated safety glass, insulating glass, thermally toughened). 

2. What applications is the glass recommended for?

  • Aesthetic interior styling (design elements such as partition walls, wall paneling or design objects).
  • As silver mirrors with advanced functionality (e.g. consumer electronics, cover panels for use in televisions and projection screens, etc.).
  • Solutions for the lighting industry as decorative and functional light covers.
  • MIRONA® Beamsplitter is an excellent product for use in teleprompter applications
  • For touchscreens (CAP /P-CAP technology).



3. When should SCHOTT MIRONA® Standard be used?

MIRONA® Standard with 34% reflection is your entry into the magical world of mirroring glass from SCHOTT.

4. When should SCHOTT MIRONA® Beamsplitter be used?

MIRONA® Beamsplitter delivers 36% reflection on one surface; the other surface is coated with an anti-reflective coating. This avoids ghost images from the backside of the glass.

5. When should SCHOTT MIRONA® High Reflective be used?

If higher mirroring is required, use MIRONA® High Reflective with 55% reflection.

6. When should SCHOTT MIRONA® High Reflective Grey be used?

The grey glass has a high-reflective coating on both sides to absorb more light, which delivers a darker background and creates higher reflection.

7. When should SCHOTT MIRONA® High Reflective One Side Coated be used?

MIRONA® High Reflective One Side Coated should be used when laminated safety glass or lamination is required. This avoids reflections from the back or PVB side.



8. Does SCHOTT MIRONA® have the same reflection color rendering as a standard mirror?

No, the reflected image appears a bit darker than it is. This is because, in contrast to SCHOTT MIRONA®, standard mirrors use a silver layer so normally have more than 90% reflection.

9. How can SCHOTT MIRONA® be installed in front of a display or TV?

MIRONA® should be integrated into a frame. The frame of the display is normally hidden by a passe-partout to conceal the adhesive joint between the frame and glass. The construction is installed with a space between the display and the glass. This space and the ambient lighting conditions affect the visual results.

10. With respect to SCHOTT MIRONA® Beamsplitter, where should the anti-reflective side be?

The AR side should normally be on the non-reflective rear side to avoid reflection from the rear. Reflection then occurs only from the front.

11. How do I avoid double images with SCHOTT MIRONA®?

To avoid double images when using MIRONA® Beamsplitter, the high-reflective side needs to be placed facing the user; the anti-reflective side should face the display. An anti-glare display (non-glossy and/or matt) is recommended to avoid reflection from the display itself.

12. How can I conceal unwanted items around the screen (for instance the TV brand, etc.)?

Either by putting a passe-partout behind the MIRONA® glass, for example cardboard or foil (the most simple and flexible solution).
or by printing/painting the glass to reduce the screen surface.

IMPORTANT: Please make sure that the color of the masking or print/paint matches the color of the screen when it is switched off!

13. How can I avoid seeing a difference between the color of the passe-partout and the screen when the screen is turned off?

By optimally matching passe-partout color and the display color when the screen is switched off, and by leaving as little space as possible between MIRONA® and the screen.

14. How can we retain the functions of the remote control on the screen if the IR sensor is concealed?

By using a material (interlayer or print /paint) which is transparent to infrared signals. Alternatively, leave a small opening in the print and position it in front of the IR sensor.



15. Which SCHOTT MIRONA® types can be laminated?

In principle, all types of MIRONA® can be laminated. We can provide you with more information on the test reports from the German testing institute Friedmann and Kirchner on the lamination of MIRONA®. Using PVB or EVA film as an interlayer fulfils EN 12543-2 requirements. Laminating MIRONA® makes sense when, for example, a MIRONA® Beamsplitter with VSG properties is to be produced by combining MIRONA® High Reflective One Side Coated (Level 1) and AR One Side Coated (AR at Level 4).

16. Is it possible to print on a coated surface?

Yes, it is. The color shade may be slightly affected by the coating.

17. What kind of material is recommended for the passe-partout?

Cardboard, foil, organic and ceramic printing is recommended.

18. What kind of printing can be applied to SCHOTT MIRONA®?

Ceramic and organic printing can be used with MIRONA®. The technology for applying the ink (screen printing, digital printing, painting) doesn’t really matter.

19. Which SCHOTT MIRONA® types can be thermally toughened?

Only MIRONA® Standard can be thermally toughened. MIRONA® High Reflective and MIRONA® Beamsplitter can also be thermally toughened using modern convection furnaces.

20. Can SCHOTT MIRONA® be used outdoors?

No, MIRONA® cannot be used outdoors. Laminated MIRONA® High Reflective One Side Coated with the coating facing the interlayer (and/or to the inner side) could serve as an alternative. The reflection of this setup is approx. 25%.
