Thanks for posting.
Three of your ink bottles are late 19th century British in origin. They are frequently called "shear-top" inks but technically they are made in a "burst-top" method. See https://sha.org/bottle/finishes.htm
The fourth example is likely also British of about the same late 19th century date.
These are quite common and have some minor value - things get more interesting value-wise in more unusual colors and shapes.
