My wife and I have a 1901 craftsman-style Victorian in Colorado. In a couple of rooms they've put a texture over the existing plaster ceiling. Is there anyway to tell if this is asbestos without sending a sample off? I should mention that my wife is nearly 8 months pregnant with our first child so I want to be absolutely no-kidding sure before I start scraping and painting. Also, the texture is over stairs that would make it a serious hassle to cover with thin drywall. Thank you in advance for your help!
