Tony has 90+ answers in Here is the MSDS for Silica which is used as the primary coating for your standard 'Frosted Incandescent' bulb:2.3.1. Inhalation: a. Silicosis: The prolonged repeated inhalation of respirable crystalline silica can cause silicosis, a fibrosis (scarring) of the lungs. Silicosis may be progressive; it may lead to disability and death.  b. Lung Cancer: Crystalline silica is classified as carcinogenic to humans.  c. Tuberculosis: Silicosis increases the risk of tuberculosis.  d. Autoimmune and Chronic Kidney Diseases: Some studies show excess numbers of cases of scleroderma, connective tissue disorders, lupus, rheumatoid arthritis, chronic kidney diseases and end-stage kidney disease in workers exposed to respirable crystalline silica.  e. Non-Malignant Respiratory Diseases (other than silicosis): Some studies show an increased incidence in chronic bronchitis and emphysema in workers exposed to respirable crystalline silica. Sure, you can put some 'Koshering Salt' inside with water (and a lot of shaking) to remove most of the silica coating but you probably can't get all of it, no matter how clean it looks.

If you're really dumb you use a Fluorescent bulb.  Don't use a Fluorescent bulb.Why do people do this kind of silly stuff?  At least find some clean Borosilicate glass... enough lamentation.Edit ArticleHow to Make a Vaporizer Three Methods:Making a Vaporizer from a LightbulbMaking a Vaporizer out of a Glass VialMaking a Vaporizer from a Shot GlassCommunity Q&A Making a vaporizer not only is easy but also saves you money. Use a few simple household items to make your own vaporizer in just a few minutes.Cavapoo Puppies For Sale In Southern California Cut the end off the light bulb.German Shepherd Puppies For Sale In Richmond Tx Fit the cap over the end of the bulb.Uab Medicine T Shirt Cut two holes in the bottle cap.

Put the vaporizer together. Place the straws/tubes into the cap and return the cap to the space over the metal in the light bulb. Once you are sure it all fits, you can remove the cap to add your preferred substance to the inside of the light bulb. Place a flame under the base of the bulb to create the vapor which can be inhaled through the straws. Cut a hole in the lid. Put the straw in the lid.Replace the lid on the vial and make sure that all the parts fit together. Once you are sure it all fits, you can remove the cap to add your preferred substance to the inside of the vial. Make sure the straw only goes about halfway down, so that it doesn’t melt with the heat or suck-up any particles. Cut the top off your water bottle. Cut a hole in the cap. Put the straws in the lid. Put the lid on the shot glass. The plastic attached to the cap should be wide enough to cover the shot glass, but can be sealed with tape if it is not. Add whatever substance you would like to the bottom of the shot glass before sealing it.

Heat gently from below. to use it put the substance in the bottom and hold a flame about 1/2 an inch below it for a while, until you see vapor fill the light bulb, then suck through the straw. If the cap is to small, you will have to get a bigger one, if its to big use tape, glue, or another adhesive. Applying any flame to glass can be dangerous. Never heat cold glass, but slightly warmed glass so that it does not shatter.When I was growing up I had a keen interest in the sciences. Mostly because of the cool gear that scientists used, you know, beakers, flasks, Bunsen burners that sort of thing. Well, not only did I not have the money for those sorts of thing but I had no idea where to even buy them if I could. So I had to improvise. One of the better improvisations I was able to do was to hollow out a light bulb and use it for other things. The glass that makes the envelope of the build is quite heat resistant and the screw base is good to attach things to (even better if you can find old ones with brass bases, you can solder to those).

I made a number of small boilers in order to learn about steam and distillation. I hope to show people that even if a bulb burns out, it can still be useful. You will need some common tools, a screwdriver (regular) and snips (or needle nose pliers). Use whatever bulb you have handy. *CAUTION* Never use a fluorescent bulb for this project, no matter how cool it looks. The powder used to coat the inside of them is made from phosphor and is quite toxic. You’re also working with glass, so use eye protection! You can’t see mine because I’m wearing them. You should also use gloves or wrap the bulb in a towel just in case it breaks. Yeah, you can’t see mine because i didn’t have any handy. So do as I say and not as I do, got it? First, grip the little solder point and give it a good twist. You will free the brass contact and break one of the wires leading to the filament. Once the contact has been pulled out, carefully crack the glass insulator. The chips from this are quite pervasive, they get into just about anything in the area and they are razor sharp.

After the insulator has been removed you can see the inside supports of the filament and the fill hole. In the old days bulbs were evacuated of atmosphere to keep the filament from oxidising and burning through. Now days the glass envelope is back filled with an inert gas like argon. The keeps the filament from burning through and makes the bulbs safer. Use the screwdriver to break the fill tube. The fill tube could be saved for a later project if you wish. You can now shake the filament assembly out of the tube. If the tungsten wire is still intact you could probably find a good use for it. You could make another light bulb if your stuck for something to do I suppose. The bulb needs a good cleaning. This powder, is called kaolin and is pretty safe. You should still be careful and keep it away from your mouth and anything you might eat near. Mind the sharp bits of glass in the socket when doing this. If you have some stubborn bits inside of it that you can’t get to with this technique you can fill the bulb with a little salt and shake it about.

this should scour the powder off the walls. There you are, an empty light bulb ready for a new lease on life. As an example I built this neo-Victorian New Age Flemming like valve out of a discarded bulb. A more traditional use is as a vessel to boil water. I wouldn’t use too hot of a flame, a candle or an alcohol burner should be about as much heat as you should use. It is after all only a light bulb. Real lab ware is much thicker and can take more heat. Still, for the amateur experimenter this can be handy to have. I hope you have enjoyed this little project and have fun making useful things out of what was once junk. A few of the dimmer bulbs insist on sending me comments on how this will make great drug paraphernalia. Please keep those comments to yourself as I delete them ASAP.  You don’t have to be a rocket scientist to make something into a pipe and that’s not why I wrote this tutorial.
