Having originally qualified as an architect, Harrison came relatively late to pottery. 

He spent a year at the LEACH POTTERY (1979-80) gaining a thorough grounding in every aspect of clay-work, from preparing the clay, throwing, glazing and firing to working in the showroom.  Janet LEACH was a valued critic, and he was able to sell his own work through the showroom.  

In 1981 he converted stables to create Trelowarren Pottery, where he created and sold his own range of domestic tableware, using Celadon and Tenmoku glazes.

In his Helston studio shop he continues to show his work alongside the woven tapestries and rugs created by his wife Jackie Harrison, and the ironwork and jewellery of their daughter Lisa WISDOM (Smythick Forge, nr Helston).
