Fair enough -- you have a lot more experience in the area than I will
ever have.  Wonder what the difference in price is due to?  Mine is
one of the little 4x1 1/2 inch (or something like that) inserts for a
normal welding mask.  

BTW: Any ideas on how to stop the mask itself from getting so damn
hot?  I've though of aluminum foil (shiny side out) but haven't done
any smithing since to try it out.  Somehow I just get the feeling that
black is a stupid color to make these things.

Thanks for the correction Steve!

I think that the difference in price is too many middle-men!

Aluminum foil or white paint sound right. Metal foil is probably
better-you want something to reflect IR. If you have a spare mask, how
about chopping a hole in the top and bottom for air, or removing the
lower half of the mask as someone recently suggested.

To tell the truth, I don't wear IR protection when forging. Instead I
minimize the amount of time I spend looking in the fire or in the gas
forge. Staring in the fire is a bad habit easily picked up.
