First, you need to determine its density, which is
mass divided by volume. Mass (or weight) is easy.
weigh it on a gram scale.
To determine volume, seal the object in a plastic
bag from which you have squeezed out any residual
air. Immerse it in a volumetric graduate (marked
off in cubic centimeters) partly full of water and
obverse the difference (in cc's) in volume.
Since it looks like it's seen lots of water already,
I'd just drop the bare object into the water and
write down the change in volume. More accurate.
Divide the mass in grams by the volume in cc's
to get the density. Look it up in this table:
