This art work is made from broken glass collected by Manchester-based artist Ana Rosa Hopkins after riots in the city in August 2011. On 4 August 2011 29-year old Mark Duggan was shot by police in Tottenham, which triggered violent protests in London. Between 8 and 11 August there were riots in many other UK cities – including Birmingham, Leeds, Liverpool and Manchester. Ana Rosa Hopkins collected some of the broken glass from the Manchester riot and turned it into this art work. You can see this and other examples of historic and contemporary glasswork in the Harris collection.
