we were interested in the long-term care of the chris ofili paintings because he uses unconventional materials obviously the elephant dung balls and also the polyester resin we wanted to experiment with the materials and the best way of doing this seemed to us to make a replica which we could then subject to test because obviously we can't test the original material we went to extreme lengths to get all the right materials we use the same suppliers and we made sure that the brands of paint were the same I was told we were getting the dung from exactly the same elephant at the beginning of the project we found out that the canvas that he used is discontinued so we couldn't buy it from the normal supplier so he very kindly found some old roles of the same canvas and donated them to us Chris replies up to four layers of priming and he smoothes each one by sanding it down and took like a marble smoothness and then on top of that he draws a graphic often quite intricate design we didn't go to the lengths at the artists did because a lot of it is covered with the leg that goes on top which is acrylic paint in a really nice swirly psychedelic design with every color of the rainbow on top of that it's very dilute oil paint which is dripped down the surface and once that's dry he he creates a sort of foliage backgrounds that foliage background is painted in oil paints he scratches through so you can see some of the colors underneath so once the foliage is finished then and we attached the dung ball which has been drying out and that's attached using a hot glue gun the next stage was to apply the and polyester resin and that's really nasty stuff the reason for making the full-size replica is we're going to drop it and see at what drop height the resin will crack or the dung ball will fall off we've made some canvases on which we painted out Chris's materials from all the different paints and the felt pen that he uses and also the phosphorescent medium and we're going to subject it to artificial aging intense light will be thrown on it 24 hours a day seven days a week for several months to see what the materials will look like in about 50 to 100 years time by having seen so many and made them myself I feel really well informed of how they're made and so that if there is anything that doesn't quite look right I understand it better like if they're if there's a crack I can maybe work out where it's come for how it was formed you always end up really enjoying an artwork when you know more about it you
