In the mountainous coastal province of Fujian, iron was smelted in a small ‘trumpet-shaped blast furnace’. The ore was ironsand and the fuel charcoal. It is interesting to see that the same type of blast furnace was used in the Philippine Islands. There is a large Chinese minority group in the Philippines, descendants of immigrants from Fujian, and it is certainly these immigrants who introduced this type of furnace here.
