Tony, A reasonable way of identifying your solder is to place a small piece of = it on top of a piece of steel and slowly bring it up to heat, the melting = point of the solder can then be determined by observing the colour of the = steel at the point the solder melts.

Thanks for the encouragement Phill. I do have some thick walled tubing, = both copper and steel, that I can use for the boiler and the flue.
