Just an FYI to everyone.
I have these old blue titanium coated drusies and decided to play
around with one the other day. Something wierd happened however, when
I tried to rubber cement (school craft grade) the drusy on to
cardstock for designing purposes. A drop of the cement landed right
in the middle of the drusy. Within 5 minutes the deep blue titanium
turned white where the cement had fallen. Just wanted to give
everyone a “heads up” on this since there wasn’t a remedy to my
mishap. I’m no chemist obviuosly!
