This article is in a pre-construction phase.
Someone is needed to work on this article which contains a few preliminary notes.

1. The localities need to be brought into conformity with mindat locality strings if necessary, reversed and made bold.
2. If image links appear below they need to be embedded in the article. If none are present the Mindat image bank needs to be searched for images of this mineral and the better ones and their localities need to be placed in the article.
3. The captions for the images need to be added.
4. The images need to be tweaked so that they look nice. This last bit is tedious and requires patience and some little artistry.

Derbyshire, Milltown. “Specimens sent to the British Museum (Natural History), London, from the oxidized vein that contains sweetite [tetragonal Zn(OH)2] were examined further and were found to contain three additional polymorphs of Zn (OH)2, one of which constitutes the second occurrence of wülfingite. As well γ Zn(OH)2 is present as a white radiating acicular material…The last polymorph (ashoverite) occurs on colorless fluorite as groups of square plates about 0.5 mm across. The mineral is colorless and translucent, progressing to milky grain centers, dull to vitreous luster, white streak, fluoresces bluish white in short-wave ultraviolet light.”1
