It provides the cleaning, you need to be sure you have the right heat for the bond. **Q: What kind of shelf life does it have, when is the expiration date?** A: I think it is almost all inorganic chemicals. Not sure why it would have much of a shelf life, but maybe the manufacturer has some info. I looked over the MSDS and there was nothing there that raised concerns about changes over time. I guess it could dry out if you left the top off. I'll be curious to see what others say. **Q: I am pouring multing lead in a mold around stainless steel wire will this help it to bond tighly to the wire ???** A: I don't know how to answer your question about pouring multing lead a round stainless steel wire? I don't think rubyfluid is what you're looking for??? I originally purchased the Ruby fluid or soldering copper on the top of my chimney before I sold my house I replaced the whole top of the chimney with copper and soldered the joints using ruby fluid the flux for soldering the copper. **Q: How many ounces is it?** A: 1 Pint is 16 fluid ounces. ## Frequently Bought Together - Ruby Chemical FLSRUBYFLUIDPT 1PT Liquid Rubyfluid - 50/50 Tin-Lead Bar Solder - 1 lb.
