The reaction between zinc powder & sulfur. In this demonstration, a mixture of zinc and sulfur produces an unusual chemical reaction when heated. A brilliant flash of light, followed by hot sparks, a hissing sound and a mushroom-shaped cloud of white smoke, is generated. It has been heated to 1500 degrees F, then doped with Copper and Silver salts. The result is known as 'Activated Zinc Sulfide'. This process makes the material glow a pale blue when exposed to Alpha radiation. Zinc sulfide, ZnS, occurs in nature as the mineral sphalerite and may be prepared by treating solutions of zinc salts with hydrogen sulfide. It was long used as a white pigment but has been gradually replaced by titanium dioxide. Zinc sulphide is a luminescent substance which displays fluorescent and phosphorescent effects when stimulated by many types of radiation. A person can apply them directly to the parts of the skin that acne affects. Some common topical zinc-based medications include zinc sulfate. Dab a small amount of zinc oxide cream on the acne spots after moisturizing your face to treat acne. Remember to check the concentration before using the product. It is, however, always advisable to consult your dermatologist before using any of such skincare products containing zinc oxide. Zinc plays a major role in regulating every phase of the wound healing process, ranging from membrane repair, oxidative stress, coagulation, inflammation and immune defence, tissue re-epithelialization, and angiogenesis to fibrosis/scar formation.
