An American writer once pointed out that there are two kinds of artists in the microcosm of sculpting. There are those who subtract, starting with a beautiful block of stone and chipping away until it results in some marvellous shape. Then there’s those who add, building with clay, piling it on and shaping it until the piece is finished. Carlos Chaclán, a Guatemalan master ceramicist, is the latter kind of sculptor, and his development as an artist is true to the way in which he works the clay.
