I have tried with 2 different types of zinc chloride flux (one liquid and one lenox tinning flux) I have an ingot of pure tin, have tried different levels of heat but no luck getting tin to adhere. What about pre-cleaning? I tried a lye pre-soak, steel wool and still tin will not stick. I have also gone through every type of cotton cloth I have to wipe and burned them all. I am soooo still looking for detailed advise. Thanks
