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>. An important specialization of this collection is <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjNlZwpEbGdrcN5Y29ycA" class="cyc_term">ChemicalSubstanceType</a> -- those substance types defined solely by their chemical formulae. steel Steel The collection of all contiguous portions of steel, an alloy of iron containing a small amount of carbon. kind of artifact not distinguished by brand or model An instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHQdVmB_TEdaAAABQ2rksLw" class="cyc_term">SecondOrderCollection</a> and a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwO3H5pwpEbGdrcN5Y29ycA" class="cyc_term">ArtifactType</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rejmDbrF_QdeIENT1qpbYzQ" class="cyc_term">ArtifactTypeByGenericCategory</a> is a collection of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkH_ZwpEbGdrcN5Y29ycA" class="cyc_term">Artifact</a>s grouped together according to some feature(s) other than brand or model. ArtifactTypeByGenericCategory A collection of tangible stuffs; a subcollection of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVisOZwpEbGdrcN5Y29ycA" class="cyc_term">Metal</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjMi5wpEbGdrcN5Y29ycA" class="cyc_term">MetalAlloy</a> is a metallic stuff which is a homogeneous blend of at least one part of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkI-JwpEbGdrcN5Y29ycA" class="cyc_term">UnalloyedMetal</a> with at least one other substance. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjMi5wpEbGdrcN5Y29ycA" class="cyc_term">MetalAlloy</a> is not a subcollection of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjon5wpEbGdrcN5Y29ycA" class="cyc_term">Mixture</a>, because each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjMi5wpEbGdrcN5Y29ycA" class="cyc_term">MetalAlloy</a> is defined not only by the amounts and kinds of its <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjSd5wpEbGdrcN5Y29ycA" class="cyc_term">constituents</a>, but also (unlike a mixture) by the internal structures formed during its creation. Furthermore, the creation process is typically more complex than <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjp8JwpEbGdrcN5Y29ycA" class="cyc_term">Mixing</a>. Common metal alloys include the instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjFXZwpEbGdrcN5Y29ycA" class="cyc_term">Bronze_Stuff</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjH6pwpEbGdrcN5Y29ycA" class="cyc_term">Brass</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjLAZwpEbGdrcN5Y29ycA" class="cyc_term">Steel</a>. Note that <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjF4JwpEbGdrcN5Y29ycA" class="cyc_term">GalvanizedMetal</a> is _not_ a subcollection of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjMi5wpEbGdrcN5Y29ycA" class="cyc_term">MetalAlloy</a>, because every instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjF4JwpEbGdrcN5Y29ycA" class="cyc_term">GalvanizedMetal</a> has a coating of some <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViGO5wpEbGdrcN5Y29ycA" class="cyc_term">Zinc</a> on its surface, and thus (unlike an alloy) the components of galvanized metals are not homogenously distributed throughout.
