No, Vaseline does not harden over time. It is a semisolid mixture of hydrocarbons that remains stable at room temperature.
Wax typically hardens at temperatures below its melting point. Different types of wax have different melting points, but in general, wax will start to harden once it cools below around 100-140°F (37-60°C).
use paraffin wax
No Bee's Wax in Vaseline. It is Petroleum Jelly - made from oil.
Cheese wax is a mixture of paraffin, Vaseline and microwax mixed together. Other waxes used are pure paraffin and beeswax.
If your braces are hurting or rubbing it would be sensible to put vegetable wax or vaseline on them.
I hope it doesn't take too long, considering my dad poured hot wax into one of our toilets. He said that he wanted to see wax harden instantly.
When wax is dropped into boiling water, it melts and forms a layer on the surface of the water. The melted wax will eventually cool and harden, creating a thin layer on top of the water.
taken from a forum: get some microcrystaline wax (monster makers sells it), vaseline, and some translucent face powder... basically all you need to do is melt the wax down (i used a washed out pop can with the top cut off that i pu in a pan of water) that's only because i didnt want to trash my good pots. combine the wax and vaseline in there about equal ammounts of each. heat until it melts completely, then add some powder. keep stirring it until it starts to solidify. you might want to make a small ammount first to get the bugs out. if its too soft, add more wax, if its too firm add more vaseline.
Place a paper towel over the wax and iron over it on a low setting. The heat will melt the wax, and the paper towel will absorb it. Repeat until the wax is gone. Alternatively, freeze the pants to harden the wax, then gently scrape it off with a dull knife.
To remove spilled wax from wood floors, place a plastic bag filled with ice on top of the wax to harden it. Once hardened, carefully scrape the wax off using a plastic scraper or a credit card. Wipe the area clean with a cloth dampened with warm soapy water, then dry thoroughly.
You need to wax it right away and then freeze the wax on it. Next you get hardwood glue and glue a chenk of waxed wood into the chipped area. After two weeks, the wax will harden completely. (That is if it is used everyday for two weeks.)
