    Take a short piece of thin (26-30 ga) Ti wire and heat it with your
    torch till it ignites have a safe place to set it like a fire brick.
    Don't look at it when it is burning it is very bright. The larger the
    piece is in diameter the harder it will be to make it ignite.
    Titanium is called a reactive metal in part due to is great affinity
    for oxygen. If you get it hot enough it will proceed to very rapidly
    oxidize ( burn) in an uncontrolled fashion. Look up titanium fire on
    google and you can find a little more information about titanium
    fires Also look at http://www.titanium.com/titanium/tech_manual/
    tech15.cfm The largest group of Ti fires are in machine shops from
    turning chips and grinding dust. Your screen is thinner in section
    than the lathe turnings they are concerned about therefore easier to
    ignite. As I said your screen may not ignite with your use of it but
    it is a concern and I would not use the Ti screen for a soldering
    surface in my shop.
