solvent such as xylene. The tissue is then placed in paraffin wax for several hours, then set in a mold with wax to cool and solidify. Sections are then cut on a microtome. Other uses Candle-making Wax carving Bicycle chain lubrication Coatings for waxed paper or waxed cotton Food-grade paraffin wax: Shiny coating used in candy-making; although edible, it is nondigestible, passing through the body without being broken down Coating for many kinds of hard cheese, like Edam cheese Sealant for jars, cans, and bottles Chewing gum additive Investment casting Anti-caking agent, moisture repellent, and dustbinding coatings for fertilizers Agent for preparation of specimens for histology Bullet lubricant – with other ingredients, such as olive oil and beeswax Phlegmatizing agent, commonly used to stabilise/desensitize high explosives such as RDX Crayons Solid propellant for hybrid rocket motors Component of surfboard wax, ski wax, and skateboard wax Ink. Used as the basis for solid ink different color blocks of wax for thermal printers. The wax is melted and then sprayed on the paper producing images with a shiny surface Microwax: food additive, a glazing agent with E number E905 Forensic investigations: the nitrate test uses paraffin wax to detect nitrates and nitrites on the hand of a shooting suspect Antiozonant agents: blends of paraffin and micro waxes are used in rubber compounds to prevent cracking of the rubber; the admixture of wax migrates to the surface of the product and forms a protective layer. The layer can also act as a release agent, helping the product separate from its mould. Mechanical thermostats and actuators, as an expansion medium for activating such devices As a potting material to encapsulate electronic components such as guitar pickups, transformers, and inductors, to prevent moisture ingress and to reduce electromagnetically-induced acoustic noise and microphonic effects Textile manufacturing processes, such as that used for Eisengarn thread. Thickening agent in many paintballs Moisturiser in toiletries and cosmetics such as Vaseline. Prevents oxidation on the surface of polished steel and iron Phase change material for thermal energy storage Used by MESSENGER (Mercury spacecraft), when the spacecraft was unable to radiate excessive heat. Manufacture of boiled leather armor and books Neutron radiation shielding Wax baths for occupational and physical therapies, and cosmetic treatments Used for wood finishing Used as a fuel for fire breathing Used in Lava Lamps Occupational safety People can be exposed to paraffin in the workplace by breathing
