    I am wondering what kind of solder is used in Olds horns, is it non-toxic. Also I recently did a thorough cleaning of my horn and a few days later I noticed white oxidation on the exposed solder joints, what could cause that?

    The low-temperature solder joints almost certainly use a solder that contains lead -- probably around 60% lead, 40% tin.

    In the presence of moisture, tin forms a white oxide.

    I guess there shouldn't be much of problem with contact, there are solder joints in the lead pipe area, and I don't play with my horn tilted up, the bacteria growing in there is probably more dangerous. I tried to search for lead in my trumpet, but it kept coming back as lead trumpet.ROFL

    I don't recall hearing much about hazards to players from the lead in solder. A repair tech did tell me that there are concerns in the instrument manufacturing and repair industries about workers inhaling lead fumes while soldering. He mentioned that some repair shops have moved to lower-lead-content solders as a result, but that these have a higher melting point and result in more lacquer damage when used to repair lacquer instruments. Also, since more heat is involved, more care has be taken to keep nearby solder joints below the melting point.

    The white oxidation on or around old solder joints, is simply that. Oxidation, which is caused by the various contributing factors of oxidation. It is still good solder. Although a good solder joint should not display too much solder. Again, without pics, it is hard to tell what you are seeing.

    Yamaha no longer uses lead solder, and many companies are starting to follow.
    My shop doesn't use lead solder anymore.

    Probably silver solder.

    Silver solder is used to solder the curved plates to the pins on the braces. It is a hard solder, and requires much more heat. More than likely they are using SAF-A-LLOY or a tin/ silver alloy (95-96%tin/ 3.5-4%silver).

    Lead based solder is primarily used for most horn manufacturers. There are trace amounts that really have no harmful effects on the player themselves. Shops and manufacturers are switching to PB free solder because of the long term effects it has on employees. It isn't silver solder it just doesn't have lead.
