The trick with Peroxide is little and often when they are under the UV
lights I use a sponge with a small amount of peroxide  and just wipe
over the ivory's. The only time i have problems with ivory's coming off
is when I used the damp white cloth method which keep the ivory damp
with peroxide for to long.

For resetting ivory's that are loose   Acrylikey is  an excellent cement
for gluing ivory's you can get a good fit because Acrylikey fills any
gaps in your but joint.  3 level scoops and the hardener just up to wide
part on the dropper,  gives you the right amount just clamp and in 10 -
15 your are ready to sand off the excess.

Barrie,
