Hello. I haven't done this in a very long time and really don't have the required materials on hand, so I will be purchasing. I have a partial chrome cobalt cast framework and need to add a wrought wire clasp. I do stock 18ga Ticonium wire for the clasp. I am intending on using a butane torch to solder, if that is possible. Suggestions please for the proper solder, flux, and wire for clasp if the Ticonium wire is wrong. I have been told that Ticonium wire is made to be embedded in a wax up and cast to-but I thought that technique went out in the 80's because it changes the structure of the metal and makes it brittle causing early breakage. But that is for another discussion. thank you for the guidance!
