Cobalt inks?

I picked up these two today. Are they inks and if not, what? One is a bit lighter in weight and color than the other and says “2 OZ” on the neck. The other, slightly heavier and darker says “77” or “LL” on the bottom. Any info would be greatly appreciated

They are indeed inks. They're quite common finds in early 20th century dumps, but always a welcome find because of their colour.

Concur. Twentieth century machine made inks. About 3-5 dollars for decorative value if in very good condition with no chips or cracks.
