Is there a reason as to why you are interested specifically in
first thank you for the numbers...
and the reason for the leaded is two fold.
Personaly i have found that the colors especaily the cooler
tones are far richer. As well as the person i am studing with
also suggests hem for a richer color. And the school i am at
doesn't want to be responsible for people not taking the safety
precautions so they now only order un-leaded.
So I have to take it on myself to find my own soures.
