While making a starter, added FermCap to supress the foam and everything couldn't have been going more perfect until I dropped in the stir bar 5 min before boil was done, It set the starter off like a volcano.

Bobby_M>>I flood the keg with CO2 for one minute with the lid off, rack the beer in to the bottom gently, seal it, flood it, vent it. If there's still O2 in there after that, F it.

Boil with bar in there. It's OK.

You're not the first one to find out the hard way that the bar goes in first.

Heard/read "wait until the end of the boil to toss in the stir bar so you don't melt it while it sits on the bottom"

It's coated in teflon and I've made quite a few starters where I boiled the bar. No problems and the bar looks like it did when it came out of the packaging.

Yep, in the lab we put the stir bars in before boiling. As someone before mentioned, it will provide nucleation sites and prevent bumping. And yea, they are fine at way higher temperatures than you'll create in brewing, so long as they're immersed in an aqueous solution. They replace boiling chips when stirring's required usually.
