PROCESS: The "Lost Wax" Brass Process
 The "lost wax" brass process is an ancient tecnique used for making brass models and sculptures. Amongst the Asante of Ghana this technique was used to mend the bones of ancestors which are considered sacred. It was also used to make the gold ornaments so beloved in West Africa. Nowadays brass is more commonly used... First a detailed model object is made completey out of bees wax. This wax mould is then hardened with ash and prepared for the kiln where recycled brass is melted and replaces the wax - which is "lost". See how it's done below.
 
Making the wax model
  Wax from the African honey bee is used First it's formed into the rough shape and size needed

  This is fiddly work - the fine strings of wax are shaped and fused to the base shape - it needs a steady hand and great concentration...
 
  After the strings of wax have been applied they are sculpted every detail made in wax will be replaced by brass
