dang did the usual slow boil cut everything off put it in a water solution of dawn and soda ash for about a week. clean it all up put it in hydrogen peroxide 27 percent over night looks good glue the teeth in plce everything looks nice. till now i'm worried that if i put it back in the peroxide it might screw up the glue . i put the upper part of the skull in it looked whiter than it dried and the yellow showed back up

suggestions ?
