This colour is achieved through skilled control of the burning process to produce the traditional naturally occuring random hues of authentic multi-coloured clay roof tiles; colours that cannot be replicated artifically with stains and pigments. The colours within this blend are rich and varied with purples & blues merging with reds and vibrant terracottas. It is this random varied quality in the firing of this blend which results in some purply blue tiles, some terracotta red tiles and some tiles which are both red and blue.
