                This is from an environmental tapelift collected
                  in a home in Lancaster, California. The bright particle
                  upper-right of center is a quartz grain with burnt clay on its surface. The particle
                  at lower-right is a natural hematite grain. A collection
                  of mold spores are at left center.
