[Crm-sig] HW S11

Hi
To get some intuiton here:
I workde with a database for a limnological collection of water samples from Norwegian streams. The water samples are store in small sample tubes. The form of the tube is not of interest. The sample is messured in milliliters. Does such a sample have a stable form? If the sample is frozen (in a an elastic tube),is it the same sample?

Best,
Christian-Emil

I broadly agree with the points made in the discussion:

1) If interventive conservation work changes the identity of an object
then it has failed. If anything, conservation work should maintain the
identity of the object.

2) Destructive testing in conservation requires a sample.
Non-destructive testing, such as taking a photo under UV or IR light,
does not require a sample. I think S13 has to be defined as "taken/removed".

All the best,

Thanasis
