I work with platinum a lot. I don't use flux platinum likes to combine with salts when liquid. The flux may make the solder joint brittle. I do flame weld all weddings where possible to as you don't get that annoying solder line drag when polishing. You have inspired me with your channel and interesting approach to difficult settings.thank you.👍
I don't know if I missed you talking about it, but I was taught to use oxygen and propane, or Brown's gas for working with platinum. Acetylene can make the metal brittle if you use a reducing flame.
I’m afraid I have to comment as there are a few things you have wrong in this video. You should NEVER anneal or work on a charcoal block with platinum! The carbon contaminates the structure of the platinum. Use a silica block instead. Just google it. I’d hate to see you produce more films showing a technique that could ruin people’s metal. Also never use acetylene and oxygen for the same reason. The gas contaminates the platinum. Also welding shanks and rings is the best method to join the metal. No solder lines to worry about and it is a stronger join. When you weld you add a sliver of metal between the joint that extends beyond the edge of the metal. So when you weld, that sliver then melts onto the surface and welds the joint. Then you file and buff that down to the surface of the ring leaving the dimensions of the metal exactly as it was. This is the correct way to join platinum.
Cross contamination is a serious concern when working with platinum. Any maker who wants to work in Pt must be scrupulous about cleaning files of any gold or silver filings (lemel). Also use separate sand (buff) sticks on Pt than the ones used on Au or Ag.
Ive always used natural charcoal with platinum again platinum likes to combine with stuff when it melts silica never had good times melting on that. Also charcoal is exothermic when it burns. Must be natural charcoal. That's my experience.
Hiya, We stopped using 1700 solder some years ago just found it to brittle, now we use Plumb solder a higher Plt content from the USA we cant get it in London ?, Also i love you torch whats the name of It ? Its nice and powerful. love all the clips you do keep up the good work mate..ex HG 70s & 80s time... Essex boy...
:/ those shades are crap and not for platinum for sure lol. *most other jewelers dont talk about this but platinum is far harder to get a fine polish and its more important to sand down grade by grade and get an almost polish on it before polishing. im a metal purist and im very much against using gold solder on platinum but he's got a point, there are some times when gold solder is needed to be used when next to stones that cant be easily removed. however, platinum/platinum solder should still always be used whenever possible to ensure stronger and seamless bonds. platinum is really such an amazing jewelry material once you become accustomed to it.
From the comments, this guy should just stop what he’s doing and step away from the desk. And his 30 year old book be thrown away and go back to school to get an updated degree.

What gas are you using?
