Some years ago we excavated a Roman horse from
very havy clay. Quite a job.
Afterwards it must be cleaned of course, before it
could be prepared. That was almost worse than the
digging. It must be done very careful, because most
of the bone was very soft. Very frustrating because many
bones crumbled in your hand or broke when you broke a
lump of clay. The skul looked nice, but in the end the
skeleton was in a too bad condition for proper preparing.
After all that work! That do I call the hard way.
Why didn't you use hot steam ? A custom hot steam cleaner with
a specially made nozzle (for thin jets of steam) should have worked
Dunno, never seen one here. Our group is not that rich,
and our professional colleagues didn't offer one. Don't
even know if they have one.
But the horse was in a bad condition anyhow, and it was
not the only one. In hindsight I think that the photographing,
drawing and measuring we did was enough.
But at least I now know how Roman Age horse bones feel.
Not many people can say that.
That method would have avoided the braking and crumbling,
and I can't think of any negative effects.
