I was wondering what these shiny flecks are in my plaster.

Customer Question

Hi, I was wondering what these shiny flecks are in my plaster. The home is 116 years old and this picture was taken when I took the vent off. You can see layers of tile, then mortar then the metal of the vent. If you can see in the mortar there are some very tiny shiny specks. Is this typical of plaster? What is it?

Most likely it's mica that's common in sand which was a constituent of the scratch coat layer it's in. Nothing to be concerned about.

This is typical of one plastering method that was pretty common in that era.

Okay- it doesn't look like asbestos?
Expert:  Rick replied 1 year ago.

Asbestos doesn't look anything like that. It's fibrous and most of the time you can't see the fibers.
