Glazing: the right solution for every need from standard glass to museum quality, including acrylic.SAMSUNG CSC

The way artwork is glazed can have a major impact. Standard picture glass (normally 2mm thick) just like architectural glass has a green tint due to the impurity iron oxide which is in the sand from which glass is made. This tint results in a spectral shift and obviously affects the colour of the artwork.

The way this is resolved is to remove the impurity during manufacture – an expensive but effective process that results in something called Water White glass.

On Reflection

As we all know light reflections can result in beautiful visual effects– but not when they interfere with the viewing of art. For some time the standard way to reduce these reflections has been to use, what is commonly referred to as non-reflective glass: which is actually etched and defuses the reflected light. While low cost, this etching results in a loss of contrast and is impossible to see through clearly if the glass is not close to or touching the artwork, which may not always be possible.

A significantly better and an increasing affordable solution is Water White glass coated with an anti-reflective coating. This type of product is available from several manufacturers and at Blackwater we source the most appropriate product for a given requirement in order to achieve the most cost effective solution. These products all have near perfect clarity with high levels of light transmission and near zero colour shift, while reducing refection to less than 1%. The result: glass that is virtually invisible.

Museum glass

This term is often used to describe glass which filters harmful UV light which will fade most colour pigments and causes paper to become brittle. However, contrary to its name it is hardly ever used by museums as they tend to filter harmful sunlight, or use UV free lighting systems.

This is always achieved by an invisible coating which can, at a price, filter out 99% of UV light although around 90% is more common.

Now, or course the anti-reflecting and UV filtering coating can be combined providing the ultimate solution for valued artwork, or framed objects.

Plastic Glass

An odd description which includes both acrylic and styrene glazing which is a must for many public locations where glass could pose a safety problem; it’s also highly recommended for use in locations used by young children. The problem; it’s an oil based product and hence expensive. It is also highly static, which can cause problems when framing pastel and charcoal art. The other problem is in its standard from its easy to scratch – although scratch resistance acrylic is available. But it is not all bad news, in addition to enhanced safety it’s much lighter in weight and is often used when framing large pictures for that reason.

The Ultimate Protection

Laminated glass provides protection against vandalism and accidental damage combined with UV and coated reflective control.
