Jean Guillaume is highly indebted to the tuition from Françoise Bizette and then Jean Lerat, and he will always remain a devoted friend to his “master”. Despite remaining faithful to the techniques he was taught, Jean Guillaume was able to find a very personal and original path. His sculptures as well as his more functional pieces always display a hint of humour. His bowls, mugs and soup tureens are anthropomorphic, with an arm serving as a handle, and a cap as a lid with a pot as a head on legs. His animal sculptures are stylised, unadorned but close to Outsider Art. Jean Guillaume showcases modelling by using just very few colours; these are created by the slips, softened by the ash and the reduction of wood firing in the Sèvres kiln.
