[Rockhounds] No Magic?!? Welder's eye

[Axel Emmermann]

Amen!
 The delay has to do about cells that are damaged but not yet destroyed.
Sometimes burn-blisters appear also a day later (sometimes even 48 hrs)

I think it's pretty much like any skin burn... 1st degree is painful but you
recover completely. 2nd degree needs medical attention and 3rd degree is
permanent.

Cheers
Axel
