Narrative:
Climbing to 8000' as assigned aircraft began to ice. I asked to continue to 10000' and controller said something like, 'ok, I'll work that out with (center or griffiss a--I can't recall which).' watching ice build I heard what I wanted to hear (clearance to above) and was at 8300' and climbing when approach woke me up. From now on I'll holler earlier about ice, even if only potential.
