These sculptural vessels are hand modelled with the techniques of pinching and Lulo. The burnishing is done with a small river stone during the drying process. All the pieces have a first firing in a low temperature terracotta gas kiln. The black pieces go through a second firing, the traditional pit firing, using llama and goat guano as fuel. The firing is done in a reducing atmosphere, which is the reason for the black colour, grays and graphites on the surface of the piece.
