ANGLESITE with pyromorphite Mineral Hill, Wakefield, NH 0.8 mm milky anglesite crystal with tan pyromorphite	Species: ANGLESITE with pyromorphite Locality: Mineral Hill, Wakefield, NH Specimen Size: 0.8 mm milky anglesite crystal with tan pyromorphite Field Collected: Gene Bearss (2004) Catalog No.: A Gene Bearss collection specimen Notes:
ANGLESITE Mineral Hill Mine, Wakefield, NH 0.7 mm anglesite crystal	Species: ANGLESITE Locality: Mineral Hill Mine, Wakefield, NH Specimen Size: 0.7 mm anglesite crystal Field Collected: Art Smith Catalog No.: A Bob Janules specimen Notes:
ANGLESITE Johnson Rd., Bow, NH Approx. 0.7 mm clear, rhombic prism, anglesite crystal	Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.7 mm clear, rhombic prism, anglesite crystal Field Collected: 2016 Catalog No.: u2145 Notes: Backside reflections through this clear crystal make it appear hexagonal in this photo. Although both anglesite and cerussite are orthorhombic, these anglesite crystals lack the striations on the prism faces. Stack of 40 images with Nikon Plan 10 objective and Canon G9 camera
ANGLESITE Johnson Rd., Bow, NH Approx. 0.7 mm milky, rhombic prism, anglesite crystal	Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.7 mm milky, rhombic prism, anglesite crystal Field Collected: 2016 Catalog No.: u2147 Notes: Flat rhombic prism termination is on top. Stack of 8 images with Meiji triocular scope objective and Canon G9 camera. Compare with photo taken with Nikon Plan 10 objective lens.
ANGLESITE Johnson Rd., Bow, NH 4 mm field of view	Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 4 mm field of view Field Collected: 2016 Catalog No.: u2147 Notes: Stack of 61 images with Nikon Plan 10 objective and Canon G9 camera
ANGLESITE Johnson Rd., Bow, NH 1.5 mm anglesite crystal ANGLESITE Johnson Rd., Bow, NH 1.5 mm anglesite crystal (center) on 8 mm corroded galena crystal.	Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 1.5 mm anglesite crystal on 8 mm corroded galena crystal. Field Collected: 2016 Catalog No.: u2154 Notes: Stack of 57 images with Nikon Plan 10 objective and Canon G9 camera
ANGLESITE Johnson Rd., Bow, NH 0.4 mm rhombic prism	Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.4 mm rhombic prism Field Collected: 2016 Catalog No.: u2133 Notes: Stack of 34 images with Nikon Plan 10 objective and Canon G9 camera. Unsure if termination is natural or broken. There is some preferential iron staining on the front prism corner.
ANGLESITE Johnson Rd., Bow, NH 0.7 mm terminated rhombic prism	Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 0.7 mm terminated rhombic prism Field Collected: 2016 Catalog No.: u2133 Notes: Stack of 20 images with Nikon Plan 10 objective and Canon G9 camera.
ANGLESITE Johnson Rd., Bow, NH 1.8 mm anglesite broken cross-section rhombic prism with distinct color zoning.	Species: ANGLESITE Locality: Johnson Rd., Bow, NH Specimen Size: 1.8 mm anglesite broken cross-section rhombic prism with distinct color zoning. Field Collected: 2016 Catalog No.: u2133 Notes: A polished crystal section grain from this specimen was analyzed by EDS. This EDS analyses (BC271 - set 19) indicated a lead mineral, but unfortunately the Pb and S spectral lines substantially overlap, so one cannot determine from the analysis if sulfur is present or not. If sulfur is present, then the species indicated by the EDS analysis is anglesite, PbSO₄. If sulfur is not present, then the species is cerussite, PbCO₃. (there is a small carbon peak at the low spectral end, part of which may be due to the presence of carbonate ions and part due to the known presence of the sample carbon coating.) However a wet chemical test strongly suggests that this is anglesite. A drop of muriatic acid on a similar partial crystal on the specimen underside gave no carbonate fizz, (indicative of cerussite, a carbonate mineral). A similar test on a known cerussite specimen gave a good carbonate fizz, validating this cerussite characteristic.
