Fragrance Oils, Heavy Or Light

I'm just learning that some FO's are either heavy or light.

When you recieve your bottles from your supplier, open them up
to see if they are light or heavy.

When a FO bottle is not full to the top, it is a heavy oil.

When a FO bottle is full to the top, it is a lighter oil.

When looking at FO's, the ones which are darker color are usually
the heavier oils.

When they arrive, weigh each one and see the difference.
