[Nhcoll-l] Using ammonia to defat and whiten bones

[Tonya.Haff at csiro.au]

Hello all,

I recently learned of the technique that uses diluted ammonia to defat and whiten bones for skeleton preparation (after maceration or dermestids). I'd like to start using that technique here, but I see that there are many different types and dilutions of ammonia that I could order. Do any of you have advice on what ammonia is optimal for this preparation method?

Thanks!

Tonya
