How can I make a simple mold?

Plaster mold casting may work.\n\n"In plaster mold casting, a plaster, usually gypsum or calcium sulfate, is mixed with talc, sand, asbestos, and sodium silicate and water to form a slurry. This slurry is sprayed on the polished surfaces of the pattern halves (usually brass). The slurry sets in less than 15 minutes to form the mold. The mold halves are extracted carefully from the pattern, and then dried in an oven.\n\n"The mold halves are carefully assembled, along with the cores. The molten metal is poured in the molds. After the metals cools down, the plaster is broken and the cores washed out."\n\nI don't know what finished product you plan to make. You say you want to duplicate a glass bottle, but does that mean you want to do it in glass, or will you do it in plastic or some other material? I don't know if this process would stand the temperature of molten glass. In that case you would be better off with what is called "refractory mold material." Both the plaster and the refractory material should be available from a Dental Laboratory supplier.\n\n"Low temperature melting materials such as aluminum, copper, magnesium and zinc can be cast using this process. This process is used to make quick prototype parts as well as limited production parts. "

you could also try a program called Blender, its from some collage and its free. it's shoudn't be too hard to find. \nlook at www.blender3d.org

An easy solution would be to use Playdough! (or other claylike materials).  It's easy to form into various shapes and stick together into a model.  And it is colorful without needing any extra painting.  You can easily add labels on toothpicks or a color key to describe the different parts.

build them yourself with a program like the GIMP or Jasc. it aint that hard... or you can get some off of google image search probably.

There are molding clays that can be used (check out the arts and crafts store).. Mold around the part, carefully remove and bake to harden.\n\nSand casting is another way to mold without using Plaster of Paris.\n\nRubber molds are also available. The molding material is a liquid rubber that you pour around the part, let it harden and peel off to form the mold.\n\nBasically, anything that hardens up can be used as a mold.\n\nHope this helps,\n\n-Guru

You+ll need a large pot, a onegallon vinegar or cider bottle, a 4' or 5' length of plastic tubing (try-airline+ tubing from a pet shop), a balloon or non-lubricatedcondom, a package of wine yeast (not bread yeast), wine bottles,corks, a corking device, and 2 1/2 pounds of honey.First you need to prepare the mixture that will be fermented. Takeyour pot and add the honey and enough water to finish filling up theone gallon bottle. Bring these to a boil slowly. If you don+t wantscum in your mead and it forms on the top, skim it off. You don+tneed to boil it for any length of time, you just need to bring it up tothis temperature. Boiling for a while will release a lot of scum andadditives which you can get rid of right now and it will also allowthe mead to age more quickly. However, some of this -scum+ as I+vecalled it is made up of those very things which can create flavornuances. I don+t boil mine. When you decide it+s done, let it cool longenough so it won+t melt the plastic tubing, then siphon the mead intothe gallon jug , cap and let cool overnight. The gallon jug is yourprimary fermenter.Did you sterilize the pot? the bottle? the cap? the plastic tubing?No! Pour it out and start again - yes I am serious.Once the mixture is cooled to room temperature you will need topitch the yeast. Get a small cup half full with warm, but not hot,water and add the yeast. Let it sit for about ten minutes and absorbwater and liven up, then pour it into your gallon jug and mix it in.As of now your honey and water mixture is now being converted intomead. However, this will take about two weeks, perhaps more, tocomplete. During this time the mead mixture will bubble and foam,and this is what the balloon is for. Cover the top of the bottle withthe balloon and about an hour later, when the balloon has started toinflate but has not become too stretched, poke a few holes in it witha pin. (I understand this may make you wince if you are using acondom.) This balloon takes the place of a fermentation lock andallows the gas to escape while not allowing air in, thus keeping thefermentation bottle sterile. The holes may become clogged withfoam and you may need to poke a few more. Just remember thepurpose of this and use your common sense. I+ve accomplished thiswith plastic wrap and a rubber band, but I wouldn+t advise others totry unless you+re fond of unmet expectations.About two weeks from this point the balloon will cease to be greatlyinflated and will eventually go limp. When it has been completelylimp for a few days and the mead is clear rather than cloudy,fermentation is over. At this point sanitize your wine bottles andplastic tubing and bottle the mead. Be careful not to get the yeastinto the bottles as it+s not exactly tasty stuff. I stop about an inchbefore the bottom of the primary fermenter and we siphon off thelast inch into cups and toast the new mead. My mead has been verytasty at this point, other people describe theirs as tasting like paintthinner. In any case, you may not mind a little yeast in your cup now,but don+t inflict it on yourself in the future by bottling it.Wait two to six months and then enjoy. Since the above recipe has noadditives which would hasten aging, it may take a while for it tobecome truly fine mead, perhaps years. There are a lot of chemicaladditives that one can use to improve the flavor and process. Themost common and important addition is a teaspoon of yeastenergizer or yeast nutrient. Others include grape tannin (1/4teaspoon), malic acid (2 or 3 teaspoons), tartaric acid (1 to 2teaspoons). I recommend all of these chemical additives in your firstbatch, but if you can+t find them you can make do with naturalingredients or nothing at all.One can also add slices of fruit, raisins, or berries for flavor and inplace of grape tannin. One recipe I know of adds some apple jelly. Afew lemon peels will substitute for malic acid and a spoonful ofstrong tea will do replace tartaric acid. Hops are a common additiveand

flour , water, salt, and pepper, cut to shape and bake.\ngingerbread cookies cut to shape make good ones also, or you can find inexpensive ornaments a the thrift stores.

no styrofoam??? aww that ruins some of the fun! i love crafty projects tho. okay you can use bakeable clay. it comes in a variety of colors and can be molded into many shapes. i would suggest working from the inside out and making it into a circle with a pie shaped cutout in it so you can see inside. basically you would make the clay figure and then bake it. you can spray it with a glossy finish and tadaa! oh, and to hang it from the ceiling? i guess you would need to screw in a metal hook beforehand. good luck!!
