I believe that with some worksmanship, a "true" consistent thickness isn't difficult to obtain. Ive seen it.
I don't think just looking at a curved piece of glass is a good way to tell how thick it is, throw some calipers on it but I'm sure it would be next to impossible right. It would have to be thinner because as you expand the tube out it has to get thinner to expand to make the beaker or bubble bottom. Its physics, for every action there is a reaction.
Just my 2 cents.

Did you hear about the rose that grew
from a crack in the concrete?
Proving nature's law is wrong it
learned to walk with out having feet.
Funny it seems, but by keeping it's dreams,
it learned to breathe fresh air.
Long live the rose that grew from concrete
when no one else ever cared. - Tupac Shakur
