I took pottery in high school. We pretty much just made bongs all semester and got A's.

"The point I was trying to make is that one couldn't make ceramic knives in a zombie apocalypse because he/she would simply lack the technology. It would be too advanced and not worth the effort and man/woman power."Oh yea, no, I fully understand. I know flint napping, so I could pretty much make a knife or arrowhead pretty easily with a good rock or piece of glass and a few other rocks I'd consider "tools". I was just trying to say that If one had the technology, they could probably just fuse lots of carbon with it and put it through a blast pressuriser and it may produce the same effect and make a knife. And then I went on a blab about diamonds and how their strength and durability are pretty much used in daily life, trying to link it to how the method is plausible in helping make a ceramic knife. I've made a fish hook out of ceramic with flintnapping once just for fun. Never tried it fishing or anything though... Do you find this valuable? |

"Hello everyone. I will be writing a guide to all things that have to do with clay. It is what I am studying in school and am pretty knowledgable about the subject. I made this thread to see what other people thought. Any ideas that people wanted to include?well i just want to say that your knowlegde of clay and your ability to make goods from clay could and probably will prove to be very valuable in the instance SHTF just think of the morale boost of eating dinner cooked in clay pots and eaten on clay plates that WiseChoice makes i mean it would bear resemblence to society and be one step back to normal living...kudos WC as you said in another post you wouldn't be the most accurate with a gun...but boosting the moral of those around you with something like this could help encourage them to fight another day Do you find this valuable? |

It wasn't a turbine it was a reinforced ceramic internal combustion engine. I believe it was a rotary engine but I am not sure. It functions to a degree and was discussed and shown on an old Australian show called "Beyond 2000" which used to air on the discovery channel. They showed the engine installed in a car on the show. The design wasn’t bought out it was a failure. They could not refine the design into a working production model.The major problem that they never could overcome was that of lubrication. The oil would be vaporised at the temperatures generated in the engine. This type of engine still had to have standard lubrication to start up the engine. After a few minutes as the engine warmed the oil would vaporise and then it would use its own exhaust as a form of lubricant. The thinking behind this was as the engine would be able to reach higher temperatures it would burn fuel more cleanly. It seemed like a great idea but it was a smog belching nightmare. The designers forgot one critical element the more gasses in the engine the less room there is for oxygen therefore less fuel for combustion. This would accumulate in the engine eventually choking it to a stall. You burned off the oil leaving thick smoke. This thick smoke isn’t expunged from the engine. The presence of thick exhaust gasses in the combustion chamber caused the efficiency of combustion to drop sharply after a while. It was abandoned not bought out because they couldn't figure out how to lube the dang thing without choking it to death on its own exhaust. LOL I just noted this is a really old thread so no one cares anymore about the info lol Do you find this valuable? |

Haha, looking back an my response on page one, I did indeed end up taking ceramics in college. I made some interesting pottery. I preferred working with gray stoneware over the more traditional red earthenware clay we also used. I made a lot of different vessels, some coffee cups, random pots, etc.I really wanted to try to make a stone canteen. The semester ended before I got a chance though... Do you find this valuable? |

"...I really wanted to try to make a stone canteen. The semester ended before I got a chance though..."Couldn't you take a leaf from lost wax casting and make a mold out of something that would burn out during firing. Like; make mold, shape clay around mold, fire, let the mold burn out, and voila, canteen. I may be totally off base, since I've never ceramicked except in grade school. ("Mommy see my flower pot!")

("Mommy see my flower pot!")"There are a few different ways you could do it, but different styles of molds would be the easiest. Your suggested method would work well - in fact, you could let the clay piece dry completely, heat it in an oven to the lowest melting point of the wax and let it drain out, and reuse the most of the wax again. In fact, you could pour the wax directly into its mold from there while it's still warm. A large glass Coke bottle or something similar would work well for this. If you had very good stoneware, you could even use glass - but that's risky, as glass shards in your drinking water is bad juju. Slip casting would also work. This is where you create a mold and pour liquid slip (thin watered-down clay) into it, as opposed to being thrown individually. Most commercial ceramic coffee cups are made this way, as it cranks out a bunch of identical cups. Making the mold would be the hard part, but it would work with porcelain as well as clay slip. You could also use a press-mold technique. This is where you just press the clay onto the outside (or inside) of the mold, let it partially dry, then remove. You'd have to join the halves, but that's not particularly difficult if the shape of the container is simple. You'd want to use stoneware, as it does not require a glaze to hold water (unlike unglazed earthenware, which is semi-permeable.) In fact, one could make a very simple water filter using fired earthenware clay. Do you find this valuable? |

LJ: Of course I would resist working with clay since unglazed pottery raises my hackles just by touching it. Even close proximity is enough to give me goosebumps. I appreciate it's usefulness, but I'd stick to wood or leather myself. Not that I'll outlive the mass of plastic available! :(
