Quan est\u00e0 funcionant la minsa corrent d’aire \u00e9s suficient per a revifar el foc. El rendiment del forn no \u00e9s molt bo, si tenim en compte les altes temperatures a que arriba el tub de la xemeneia quan est\u00e0 funcionant i que indiquen una gran perdua de calor cap a l’exterior. Malgrat aix\u00f2 hem arribat a fondre alumini i llaut\u00f3, ra\u00f3 per la qual podem afirmar que hem assolit temperatures de m\u00e9s de 900 graus. Aquest forn es va fer servir pels tallers de bijuteria als que es van fondre uns quants motius per a collarets, clauers, etc<\/p>\n
