Anna Airy painted A Shell Forge at a National Projectile Factory, Mabley Green, Hackney Marshes in 1918. ‘This piece was a particular challenge because she had to work with great speed to capture the colour of the molten shells. The tremendous heat of the interior added to the intensity, and one one occasion the ground became so hot that allegedly her shoes were burnt off her feet’ IWM. Nb. Mabley Green sits in the shadow of the 2012 Olympic Park. There was a very good piece in the Independent about women war artists here.
