The procedure is simple: A woman rubs a small piece of sapwood against a flat stone, slowly adding a few drops of water at a time to form a paste.
Pagatavot to ir pavisam vienkārši: nelielu koksnes gabalu berž pret plakanu akmeni, laiku pa laikam pievienojot nedaudz ūdens, līdz ir iegūta viendabīga masa.
