Working with bronze is expensive: from the beginning of work before it is completed sculptor goes a long way. Here and molding, and casting, and metal processing, and tinted glass. Ceramics less labour intensive, but no less responsible. Indeed, the idea that you convert, not dependent on the material it is from the soul and the «belly», from all your essence and inner energy. The idea captures the artist as a whole, and and get rid of it can only be making a new job.
