Gerhard Richter - Cologne Cathedral

Finished this August, this impressive stained glass window in Cologne Cathedral has been made from 11,500 four-inch 'pixels', cut from antique - or handmade - glass in a total of 72 different colours, and measures 110m2. Richter is an artist who works in many different media, and this window relates to his 1974 painting entitled '4096 Colours'. In the transition from painting to glass, Richter didn't use the original 4096 colours, as they would've been historically inaccurate or too pale, outshining those squares around them. Instead he chose a palette to echo the colours of the glass that would've been available in the 13th century.
Apparently the Archbishop of Cologne isn't happy with the window, preferring the more traditional figurative approach. The window seems to link the 21st century with the 13th very successfully, both in its' use of antique glass and with the archaic hues, but also in its' mosaic-like appearance. Medieval glass uses lots of little pieces of glass and is rich in colour and texture. I likes it, me.

Artisan mizmo ??!!

If you're thinking 'Artisan what?' or 'mizmo who?', then we're in the same boat... I found these photos in Flickr, and they were credited to Artisan mizmo, so I feel obliged to do the same.
The panels use very simple painted decorative techniques to great effect. If you want to add detail and pattern in addition to that which the lead itself makes, this is a really effective method.
All of the panels have had the paint applied all over - a matt - and then, when it's dry the paint has been scraped away with various implements to reveal the coloured glass beneath. Just like that wax crayon thing we used to do at school!
The red centre panel in the bottom one is red on yellow flashed glass - it's been freely etched at the top to reveal the yellow base layer.
