The best method for heating copper tubing with nichrome wire involves wrapping the copper tube in ceramic paper or cloth, then tightly coiling nichrome wire around it. This assembly should be secured with steel wire to maintain contact between the nichrome and the copper. It's essential to ensure that the insulating material can withstand high temperatures without emitting harmful vapors. Additionally, users should consider the expansion of nichrome when heated, which may affect its tightness around the ceramic. This approach effectively combines insulation and heat transfer for optimal performance.
