Why does refilling a hot alcohol lamp is not allowed?
142093
The problem with most alcohols is that they burn without a flame, or a flame that hardly visible.  If an alcohol lamp is hot, it may not be easy to determine whether or not it is still burning.  Refilling a lamp while it is still burning presents a serious fire hazard, let alone an opportunity to get seriously hurt.\n\nI'm not certain as to where it's "not allowed" (perhaps your school chemistry lab?), but it's certainly a good idea not to do it.

3.\nOne to change the bulb and two to make cocktails.

u can't go back to the distribution center to get a refill.

2 reasons really, courtesy for the next person, and if you let the alcohol level drop below the wick, the next burning will not be a burning of alcohol, but of the wick itself (and as it burns down into the alcohol burner, it can ignite the fumes, creating an explosion)\nI need to ask.. where are you that your lab is still using alchohol burners instead of bunsen burners?

A hat?  A bottle top?  A limit?

The gas mixture within the latest halogen lamps is designet to interact with the tungsten that is vaporized from the burning filament so that it will not coat the interior of the lamp glass, which wpi;d otherwise dim the bulb, thus extending its lifetime.  It can also be used to affect the spectrum of  the emitted light, with differing gas mixtures altering the emission spectrum.

what type you talking about?  If it's wine, you gotta store that at cool temperatures in the dark.  But for other stuff like hard liquor, i believe you just gotta keep it away from open flames :-)

Couldn't you evaporate the solvent? I think it's water or ethanol.

have a resivoir for the alcohol, have a wick that will pull the alcohol up, keep other flammables away from the flame source, have a fire extinguisher ready, don't drink the isopropyl alcohol.  Use the tip of the blue portion of the flame for heat.

If it had boiled dry it was way to hot and you don't know what that did to the internal components. With the fire risk that could impose, I would either have it looked at by a certified repair center for that brand or buy a new one. If there was still liquid in the pot, the risk would be greatly decreased. My husband is the world’s most forgetful person so eventually we had to get one that automatically shuts off an hour after it brews. Lots of them have this feature.

Old flourescent lamps needs a starter switch because flourescents bulbs are made of enclosed mercury, argon and phosphor. Electrical current can flow freely through the tube but it will not light up. When you hit the starter switch it produces an arc, then electrons collide with the atoms and other gases to produce a plasma. Today, we have the rapid start lamp. Same principle, but it doesn't have a starter switch. Instead, the lamp's ballast constantly channels configured current flow resulting a voltage across the tube to heat up electrode filaments very quickly, boiling off electrons, which ionize the gas in the tube. Then the voltage difference between the electrodes establishes an electrical arc to turn on flourescent lights.

We aren't supposed to.  Once you hit Kuwait, you are not authorized to drink alcohol until you leave.  We had that fake near beer in the chow halls, (all the taste with out the buzz!) but any mind altering chemicals are not allowed.  My roommate went over there the year before I did, and said that they got two beers and a shot of rum on the Marine Corps birthday.  But that was it.  When I went, we didn't get anything.  Does it happen?  Sometimes.  But not as frequently as your other answerers seem to think.  If you get caught, you'll ruin your career.  They take that regulation pretty seriously.

THATS FALSE, ONE SHOULD FILL IT WHEN ONLY HOT. DUH.

Since you mean the light bulb is good, then a whoosh of the gas Argon will come out of the bulb.  If you were careful, you could do this without breaking the bulb.\n\nDon't try to do it unless you wear protective eyewear and hand protection!  The bulb is under some pressure; it is not a vacuum.

Black lights don't work.  Think of how many halloween parties you were at that had one of those and there weren't splotches on the couch and chairs (or heaven forbid on the sheet the guy used to look like a ghost).\n\nYou need a 366nm UV lamp, not a 254 nm lamp.\n\n\nWhat about washing or disinfecting the furniture when you get it instead of buying something?  It would also be weird going into a store, asking them to turn the lights out and then using the lamp.  Plus you have to explain why you are looking for splooge.

i have never released the pressure before refilling my butane lighters- if possible, turn your flame as low as it will go, and hold straight vertical. you want to come straight down on the valve, so you dont break or bend it(lighter.)my husband fills lighters with several short "bursts"of butane, but i usually just do 1 to fill. what may be happening is that the butane is leaking right back out of lighter, so what you might want to try is, after filling, flip the lighter back  right side up, and ALWAYS wait until lighter is no linger cold to the touch before trying to ignite. i hadn't had any luck with butane refillable lighters until just here recently, so i can feel your frustration. hoppe this helps!!
