I get it from my suppliers of French polish etc. but you can search for a supplier in your area. Since the prohibition of lead oxide paints titanium is widely used for paint and it is not expensive. It is also completely harmless (except on black dresses of course!) and is used in food products. Titanium white is powder of a very dense white and if anything I believe it will enhance the adhesive properties of the glue. I have never used anything else, so I can't speak for zinc oxide etc. and I'm not sure what it was they used in the old days before titanium was discovered, but as I said before they would have used titanium if they'd had it.
