I'm interested in trying to do something with the dozens of old CD's and DVD's. I was thinking of trying to melt the polycarbonate and shape it while it's Pliable. I understand polycarbonate melts at around 150 degrees C, so it's possible to melt in an oven, but is it safe? Will it release any toxic fumes, or does it only vent at higher temps? Also, will it deform\shrink as it cools, or will it hold it's shape? Thanks!!!

Hello. I found this hanging lamp at a garage sale, had to have it... Cannot find any information on this style. Looks homemade, melted plastic strips. Does anyone have any information you could share with me? How it was made? Maybe when making things like this was popular? Was it possibly mass produced? They kind of look like Fruit RollUps....Anything at all would help.

I am intersted in purifying water through freezing. I know when you make ice cubes, the white cloudy stuff/minerals/solids gets frozen in the center and therefore is the last thing to thaw out back to liquid. I was wondering if that would be about what snow would do, or would it have to be a solid block of ice for that to work? I don't have a dissolved solids meter or I would test it myself. I'm pretty sure snow is fairly pure to start with, but I could be mistaken. It does have a taste to it. What is that taste?

Hello everyone, Iam a disabled pensioner living in Australia. I have a few pieces of silver jewellery where links have opened, and require "soldering". A jeweller has quoted me $40 each repair. I have a 3 inch square of silver sheet left over from a jewellery course I took years ago, and want my husband to melt it on the links for me. He has tried a hand held soldering iron and also a blow torch, neither worked. Please can someone advise us what else to try ? They are only minor melts required, but we cant make the silver molten in our garage. Many thanks

Question by Waveform19 | last reply
I have been experimenting with transistors for 3 days now, both NPN and PNP. So far I have concluded nothing. I figure the easiest thing to do is to make a transistor work as a switch. With the NPN, the current seems to flow from the base to the emitter automatically. My understanding is that current should flow from the collector + to the emitter- only when I apply voltage +? to the base, is that correct? I donât even need to connect the collector on the NPN and current flows. I have also read a million things about transistors online. My experiments seem to disprove most(all?) of the findings. This leads me to one conclusion. Iâm not doing something right. Maybe I donât have the right transistors. I have no idea. I have been using radioshack NPNâs (276-2016) and PNPâs (276-1604) When it tried to make a switch with a PNP my voltages was going back through my emitter to ground. If I disconnected it the system(test led) no longer worked. You might need to know that I was using a 5v voltage regulator to supply a 10v 5v and ground leads for my experiments. I was getting odd voltage readings on my circuits so I put diodes on the leads. The diodes stopped my PNP from working(I figured the current was flowing odd waysâ¦back in the 5v+?) and didnât seem to effect my NPN experiments. So I figure Iâm closer on my NPNâs than my PNPâs. I wish I could explain better but my brain is about to melt. My wife is mad at me because I am obsessed with making this workâ¦ please help :P

I want to melt PET plastic at home. I want to make a clear tube. I know i have to dry the plastic as much as possible to keep it clear. I will dry the plastic by exposing it to a lower temperature than its melting point for few hours. I plan to melt the plastic into a liquid and pour it into a mold. For the mold i will use 2 fire resistant pipes,and pour the plastic in the gap. Are there any hazards to this,like toxic fumes? Can i use 2 fire resistant pipes as a mold? Is there a better way to dry the plastic? If i forgot to ask something important please answer that too. thank you for the answers.

Hi ... could someone explain me, why may car charger FUSE has been melted down ??? I was using it several times, and suddenly I realised, that it doesn't work. So I have inspected the fuse, and the wire in the middle was completely melted - a lot of small drops. I have changed the use ... it worked 3 times and again. The next one as well. Unfortunately I can't tell you, if it stops work when the charger is in the socket and I start the engine or by having the engine already running and then trying to put the charger in the socket. I think, I did both of those situations ... but I'm not sure. But WHAT COULD CAUSE THE MELTING of the fuse, when before it was working OK ??? Thank you in advance, Zholy

Question by Jakcavar | last reply
Aloha, I am working on recycled PET plastic for art projects. I have read everything that I can find on melting clear PET and reforming it. My issue is it keeping it clear or at least translucent for the art projects. I cut clear water bottles into small pieces and place on a cookie sheet and place in 500F degree oven. In about 3 mins it is liquid, still clear, and in the shape of the round pizza pan it is in. Almost immediately after I pull it out it begins to cool and turn white and opaque. So, my question is, is there something I can do to keep it clear? Is there possibly a cooling process to do this? Maybe slowly drop the temperature? Any help or tips will be greatly appreciated. Aloha, Tim

This probably looks like a really strange thing to ask, but I need to know what kind of temperature K'nex can endure before it softens and/or looses shape. I am building something which will need to be able to withstand hot water/steam splashing onto it (but not submerged in it), as well as being near a considerable heat source. I've look for what they are made of, but nothing has come up, though I presume they are made of a mix of low-to-mid-temperature polymers with a high toughness. Don't get any mad ideas!!!

We're facing this situation with black masterbatch for LDPE in extrusion lamination process where some of the masterbatch granules are not properly melted and mixed with LDPE, which creates a lot of defects in the lamination. I've tried a number of Black masterbatch samples from different companies and in different prices and the problem still exists. Increasing the extruder temperatures doesn't seem to be helping either. This happens only with Black masterbatch and all other masterbatch colors melt and blend in with LDPE to give an uniform color strength. Appreciate your professional advice on preventing this issue..Thank you!
Question by hasitha.saveco | last reply
Hello. I would like to know what is the melting point for most integrative circuits epoxy molded plastics ? The kind of plastic I am talking about would be the ones used for BGA chips found in smart phone IC's (integrative circuits). I would think that a decent powerful household kitchen microwave should have enough power to melt this type of epoxy material used for BGA IC's. I would like to de-cap the BGA. PLEASE note that I will be using a cheap throw away kitchen microwave to melt the IC and the BGA is not important even if the heat generated damages the die layers made of silicon. This is strictly for hobby purposes. The same question but does anyone know what kind of metal is the bottom part (the tiny metal circles ie solder balls) of a BGA IC made from ?

Hi Everyone, this is my first post on this site! I am seeking advice to help me construct a home-made melting point apparatus (M.P.A). A melting point apparatus allows it's operator to determine the melting point of a chemical sample by heating it in a controlled fashion and noting the temperature when the sample melts. I have most of the design made up in my head, but I'm not sure as to how I can obtain the proper heating element. The heating element I am seeking is an emulation of the M.P.A.s heating elements in my school's chemistry lab, which look like this: a metal block (about 3cm tall by 2cm deep by 3 cm wide) with vertical holes bored into the face with a pane of glass pressed against said holes so a glass capillary tube (containing the sample) can be slid into the bored hole and viewed through the glass pane as the sample is heated by the metal. Another hole is bored into the metal, adjacent to the sample hole, for a thermometer. So again, my question is do you have any suggestions as to where I could by a heating element like this? Or, any suggestions on how to build one? I have a jewelry shop at my disposal so I can probably bore any holes myself. Any suggestions will be appreciated, thanks!

I've made several attempts to melt down a tin alloy metal (92% tin, 8% antimony) to make pendants; small pendants for necklaces. I haven't had any luck with this at all! The mold has been cast - the metal has been chosen but...my process isn't working. I'm using a hot plate and a small teflon pan to melt the metal. The problems I'm running into are: Once I melt the alloy, I can't get it into the mold before it starts cooling. It pours out too quickly from the pan, then cools too quick to finish pouring. It's a small mold (1 3/4" diameter with 1/8" lines) which isn't helping I'm sure. Not sure on a couple things I'm hoping somebody who know more about this than I do could possibly make some suggestions. I don't know if I should be using a flux to keep the metal clean because it is getting dirty after the melting. I don't know how to get it from the pan to the mold before it cools? Someone, I'd imagine, must have come out with a tool for transferring small amounts of metal to molds. I tried a glass eye dropper today but didn't have any luck with the transfer process. Not sure if a crucible and flux is the way to go or not. If so, does anybody know of a good company that has items designed for this type of work? Any and all help / info / suggestions would be greatly appreciated!! Thank you

Good day viewers! I recently found out about the wonders of electric furnaces, cheap to run and no smoke. I went looking around for some designs, there are some nice i'bles about it and I got very exited since my neighbours already start nagging when I strike a match, an electric furnace would be the perfect solution. I decided to go with kanthal wire, its relatively cheap at a few bucks per meter, and it can handle temperatures up to 1300C. I plan to melt alluminium and maybe some brass so I should be fine with that. now to the questions part, I have an ATX PSU with a 12V 16A output (DC), I was wondering how many (centi)meters or inches for the americans under us, it could power (if I can power it it would eventually go up to full temp right?) I am a complete nitwit at these Ohms formulas and electric furnaces, at the moment I am abstaining from sleep to build this furnace and I am sure that others are as well. I hope some nice fellow diyers can help me with it. This could be a dumb questions, maybe I need a wall outlet (230V in my place) or maybe I need some rocket science. I don't know, do you? kind regards and a thank in advance from 2 young exploramenters that want to melt some metal without ruining our lungs. excuse us for spelling mistakes, this written by non-native speakers and with shaking hands,...
