It is always interesting to go to an art exhibition and admire different people's work; but even after you've finished looking at everything, sometimes you are just not ready to leave. Perhaps there was a particular piece that caught your eye and deserves a second glance - or a third or a fourth. Maybe you are not ready to say goodbye you it. I mean, surely it would look better hanging on your living room wall than in a gallery? But short of committing robbery, there is not much you can do except buy the exhibit's catalogue and look at an inferior print in the page of a book.
That is why I like exhibitions that give visitors the chance to buy. The De Morgan Centre is currently holding such an exhibition at its gallery in Wandsworth. Contemporary meets classic in a showcase of TeePee Glass. The collective was formed by eight glass artists who met while studying at Central St. Martins; they each create beautiful and stunning artwork using glass, each with its own distinctive style. For example, Lucy Alexander Batt makes elegant vases with vivid colours, while Andrew Boddington uses air bubbles to enhance reflective light; Alex R.'s beaded glassworks create almost mosaic-like images, and Wendy Stone brings secular images to stained glass. My personal favourite is Brett Manley's optical illusions.
The exhibition is open until the 11th January; entry is free, and art can be bought starting from £15.
