フィラデルフィア美術館のインスタグラム(philamuseum) - 1月27日 00時50分

Nope, this isn’t a transformer—it's an x-ray flourescence machine, and we use it to determine the age of a painting without having to take a sample. Don't miss Final Fridays: Weird Science tonight. One of our own Conservation scientists, Kate Duffy, will be in the galleries to give you an inside look at this machine and tell you about some of her favorite projects. #philafriday
