From what this says yes it's safe
I've seen and I have recently put a glass bottle in my tank.
Be sure to clean them first with only hot water no detergents!
Another way to be sure they are safe is after cleaning put in a bucket filled with dechlorinated water and test the ph. Leave the in there for over a week and test again and if their is little to no change they should be alright.
