    Not really. I sometimes leave them in over night. No damage.

    were you getting 35% at?
  5. From what my skull guy told me it is now more like 30%.

    He said something about the department of homeland security having some problem or concern with people getting 35.

    I use straight 30, after 48 hours, that is all I need on fresh stuff with my process. Any longer than that and I see erosion on thin spots, and teeth dissolving.

    thanks mr.t! thats what i was trying to find out.
  9. 35%....48 hours no more...most if degreased properly will only need 24 hours or less. Depending if you want the teeth white or stained. Other factors play into it. If you degrease in lacquer thinner make sure you dry them completely as the interaction between lacquer thinner and the peroxide will dissolve the bone quickly. If you are simmering your skulls and using soda ash, the soda ash can weaken the bone and the peroxide will eat it up quick if you are not watching it.

    Univar in my area now requires a site visit to purchase 35% or 50% Home land security requirement. It is to make sure you are a legit shop and are storing the peroxide in a locked building.

    No more than 24 hours, if u are degreased that's all u will need.
  13. Out of curiosity, not sure it even matters, but after degreasing do you guys dry the skull before putting it in the peroxide or just put it in?

    I always dry mine first. Not sure if it matters or not but its just the way i always did it.
