Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjVWpwpEbGdrcN5Y29ycA" class="cyc_term">NaturalTangibleStuff</a> is a naturally occurring partially tangible thing.

Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjD0JwpEbGdrcN5Y29ycA" class="cyc_term">OrganicMaterial</a> is a tangible thing composed of one or more types of organic <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjwspwpEbGdrcN5Y29ycA" class="cyc_term">Molecule</a>. Instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjD0JwpEbGdrcN5Y29ycA" class="cyc_term">OrganicMaterial</a> usually have their origin in the bodies (or other products) of living things.

Chemically, instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjD0JwpEbGdrcN5Y29ycA" class="cyc_term">OrganicMaterial</a> have fairly (or very) complex carbon-based structures.

OrganicMaterial tangible stuff type TangibleStuffCompositionType A collection of collections and a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVny6pwpEbGdrcN5Y29ycA" class="cyc_term">ExistingStuffType</a>. Instances are subcollections of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> whose membership is based only on the physical and/or chemical composition of their instances. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViGSpwpEbGdrcN5Y29ycA" class="cyc_term">TangibleStuffCompositionType</a> does not have as instances collections whose instances are determined _solely_ by the physical state they are in -- for that, see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvgDEAJwpEbGdrcN5Y29ycA" class="cyc_term">TangibleStuffStateType</a>. However, many substances that chemically break down before melting (e.g. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjc_ZwpEbGdrcN5Y29ycA" class="cyc_term">FattyTissue</a>) _are_ included in this collection, even though they exist solely in one physical state. The collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViGSpwpEbGdrcN5Y29ycA" class="cyc_term">TangibleStuffCompositionType</a>, as instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a> are all pieces of substance with the chemical composition H20. On the other hand , the collection of all pieces of ice (i.e. (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwPzX0JwpEbGdrcN5Y29ycA" class="cyc_term">SolidFn</a> <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a>)) is not a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViGSpwpEbGdrcN5Y29ycA" class="cyc_term">TangibleStuffCompositionType</a>, because membership in that collection depends on the substance's composition _and_ on its physical state. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVikqZwpEbGdrcN5Y29ycA" class="cyc_term">TalcumPowder</a> is not an instance of this collection because a fused mass of the substance would no longer be powder, but would still be of the same <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViGSpwpEbGdrcN5Y29ycA" class="cyc_term">TangibleStuffCompositionType</a>. Further instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViGSpwpEbGdrcN5Y29ycA" class="cyc_term">TangibleStuffCompositionType</a> are <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi30pwpEbGdrcN5Y29ycA" class="cyc_term">Nylon</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjxdpwpEbGdrcN5Y29ycA" class="cyc_term">GasolineFuel</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjc_ZwpEbGdrcN5Y29ycA" class="cyc_term">FattyTissue</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj8apwpEbGdrcN5Y29ycA" class="cyc_term">Nitrogen</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViG-5wpEbGdrcN5Y29ycA" class="cyc_term">Glass</a>.
