SCHOTT Mirogard Ordinary float Glass Ordinary float glass is produced from Silica sand containing a large number of metallic impurities (namely ferrous oxide otherwise known as iron). When viewed from the side, ordinary float glass contains a strong green colour this is as a direct result of the metallic impurities. Often this isn’t particularly noticeable by the framer, however when placed alongside ‘Low iron’ or ‘WaterWhite’ glass there is a marked difference. Does the green colour matter? The green colour of ordinary float glass will change the colour of any mounts used, especially when viewed over a white or a cream mount. And don’t forget if the mount is affected, then the entire artwork will also be affected! It should be understood that ordinary float glass is perfectly suitable for the majority of framing jobs, however if colour is of paramount importance then you need to use a colourless (low iron) glass such as ‘WaterWhite’. Schott Mirgard SCHOTT are the originators of AR (Anti-Reflective) WaterWhite products and as such have been a worldwide leader for over 20yrs. The process used to produce their Mirogard product range is called the ‘Sol-gel’, which they use onto a very high quality WaterWhite float to which AR or optical interference coatings are applied. Mirogard WaterWhite float glass is produced on a low iron float glass, which is colourless and appears clear to the eye, eliminating the typical ‘green’ cast associated with normal float glass, allowing better colour rendition of artwork. Furthermore, multi-layered low reflectance (AR) optical interference coatings are applied to both sides of the glass, making cutting and application much simpler. Made up of 3 coatings per side, the optical coatings called ‘Optical Interference Coatings’ have an anti-reflective property, reducing the reflection of the glass surface to less than 1%. This optically coated glass gives an almost invisible quality when placed against any Artwork. Overall SCHOTT Mirogard transmits 99% of visible light, in comparison with normal flat glass which transmits only 90%. A 9% shift doesn’t appear much on paper, but when you consider that the human eye can detect differences of less than <1%, you WILL see the difference. SCHOTT Mirogard has a magical effect and the result is amazing, improving image clarity, contrast and colour rendition on most images and in particular 3D objects. 􀀹 The WaterWhite substrate that SCHOTT Mirogard uses is considered to be of the highest quality when comparing to similar manufacturers. 􀀹 SCHOTT Mirogard is easy to clean. Finger prints and other marks clean off with easily with a soft cloth and a mild cleaning agent. (as with all speciality glazing products, we recommend that you avoid ammonia based cleaning agents, as these can harm the coatings) Available in 3 variants and a variety of thicknesses and sizes, including laminates.
