What type of glass is this?

I need help. What type of glass is this and how old are these jars?

I have these jars with lids. I think they might be from a pharmacy or something like that. They all have handwritten numbers underneath. That makes me think they haven't had labels but probably have been placed on numbered shelves in some sort of system. The lids are not exactly the same size and therefore feel handmade or handcut in some way. The jars are very similar but the lids fits perfectly only into each specific jar. So they seem to have been individually made (jar plus lid). The jar that weighs 218 grams is with its lid 10,5 cm, the jar that weighs 213 grams is 10,7 cm, the jar that weighs 210 grams is 10,7 cm. The lids are quite heavy and sturdy like if they were made to really make sure it was airtight and to get a god grip when you open/close them.
I think this is glass but to the touch it feels like a combination of glass/porcelain/marble. It is hard to describe but it is very smooth to the touch but doesn't look "glossy" or shiny. There are a few ships under the lid that makes me think this is glass even if it has a stone or porcelain feeling to it. As you can see in one close up of the lids where there has been wear it is almost like "pores" (microsmall holes).
I am greatful for help and ideas on this.
I live in north europe and these are probably from europe.
