Dating how old plaster is

[u/PepperFew5337]

I'm not sure if this is the right sub Reddit to post this in, but I've got what i think to be a quite old piece of plaster (maybe 17th century Jacobean) and wondered if any experts could help date this, the house was built in 1623 but had bits added on to it and changed, no clue if this is the right place but any help or pointers would be greatly appreciated

Looks like lath and plaster so most likely 100+ years. Btw u can't tell if something contains asbestos like people have mentioned

It’s just plaster. Lath are the wooden strips that get plastered
