The materials used within this collection are predominantly sourced from The Oxford Set of Mathematical Instruments. Marketed in over 100 countries by Helix, a company based in Stourbridge, West Midlands, this set of instruments has been used in mathematics and geometry lessons by generations of school children in the UK and around the world. 
 Responding to an exhibition brief Donning Oxford the grammatical debate surrounding the 'Oxford Comma' and the city famous for education provided an interesting starting point for a collection of brooches, utilising a re-purposed local tin which was appropriately named.
