Lin recalls that when silversmiths used to join silver they had to light an alcohol lamp and blow through a bronze blowpipe to heat the metal. Then it could be hammered and brazed. This technique of using a blower to control the heat is known as "blowing fire."
林啟豐記得，以前銀飾的加熱或焊接，是藉著酒精燈的熱度，配合銅製的吹嘴集中火力使銀軟化，便於槌打焊接，這種靠吹氣力道來控制火焰強弱的工序稱作「吹火」。
