Word for a small short cylindrical glass container (for salves, creams etc.)
Solution 1:
I make salves, so I often buy containers online. Most websites call a short jar a "squat jar." It usually has a wide mouth in comparison to its height. Here's a picture of one in an online shop.
Solution 2:
There is no height limit on a jar. I have several in my fridge that are less than an inch high and some are several inches wide.
It is perfectly fine to call a small container made of glass or ceramic a jar.
Solution 3:
Another word for such a container is a tub.
