Just fixed my favorite pair of glasses with Tix solder and flux. Very kewl! They started to come apart at the transition between the rigid and flexible parts of the earpiece, which was welded or soldered. I'd been using my back-up glasses (perfectly round wire-rims) for the last few days, until I remembered I'd found the hard solder.
I also just did a temporary plumbing fix with self-amalgamating tape. I sure hope it holds or it'll be not so good to be me. Another bit of galvanized pipe, a 90-degree bend as usual, has started to pinhole -- I need to remove all the old iron pipe and finish the previous owner's partial conversion to copper. Too bad he didn't believe in dielectric unions! Worse luck, it's the hot water run that serves the kitchen and there's no shutoff other than right at the water heater.
1. Tix, "The Hardest Soft Solder on Earth," so on Mars there maybe is better, then? If that doesn't suit you, these guys have about every other kind, too.
2. This kind of union, you want. Or you have issues; you cannot have iron and copper together in water (unless it's distilled): there is a voltage. Then there is galvanic corrosion. After that, there are plumbers. Swift on their heels, bills. Big, fat, happy bills.
