The Irish Sculpture “Blue bull” is cast in bronze and individualised with textures and tail shape. The original sculpture is flame cut and carved in steel. It is then cast in bronze. Each casting (9 in total) is worked on back in the artists studio. The casting is refined, textured and the horns and tail are added. This leads to each sculpture being, in its own way, a unique piece, individually worked on by Ronan. The final patination and waxing gives the finishing touch.
