Is it safe to heat ceramic bowls and cups and stuff on a hotplate or cooktop? Like plain white ceramic stuff. BTW: The piece in question is almost certainly stoneware, not porcelain or earthenware.

I'm in ceramics at my school and i was planning to make a lantern and wanted to make a handle for it. I was thinking of making a mold out of white talc and getting it fired. Then putting copper in the mold and firing it again. Is this idealistic, or better yet would it work?

Ok I will admit I haven’t really looked around the web too hard to find a solution for this but then why go to all that bother when I can give you guys the pleasure of flexing the knowledge muscles. I like a mug that is a bit of fun, I have Taz ones, Carry on movie ones, huge ones & now I have a saucy captains mug with a long row on rosy round bottoms on it. I have to use this particular mug at the moment because our new kitten 'ible loves to play on the window sill right alongside where my mug always sits while I am working on the laptop, the wide base of a captains mug is the only one in the house the kitten cannot tip over :-) The problem is that our stainless steel spoons leave unsightly grey marks on the glaze when the tea is stirred; I have tried removing them with a scourer to no avail & it now really getting on my pip :-( I know the chances are it is because of the inferior glaze on cheap mass produced ceramics but that doesn’t help me get rid of them. Any ideas folks?

Hi all, Just wondering if anyone knows of any minerals, or products that will produce a visible fluoro colour in daylight, or phosphorescent in the dark. I want to be able to either use these as glaze or as stain for clay slip.

I've heard that you can use an unfinished ceramic tile as a pizza stone. I have not been able to find any unfinished ceramic tile anywhere. I figured a bunch of DIY folks like the ones here might know where I can get one. Does anyone know where I can get a 16"x16" unfinished ceramic tile? Thanks Rick

I'm looking to bond a bifurcated ceramic fish figurine to a glass window, such that half the fish is outside (exposed to the elements) and half is inside the house. The fish figurine is not perfectly smooth, but it's close. I live in Ohio, so external temperatures will range from 0 f to 100 f. What do you recommend? B.

A friend asked me to fix his tv's power supply, and i accepted the challenge. Upon closer inspection of the circuit board of the power supply, i saw that a resistor bridge, a rectifier, a diode, a capacitor and 2 power transistors were blown. I purchased the appropriate replacements, and as i was about to install them earlier today I saw that two ceramic capacitors are blown. One of them has '684J' printed on it, the other has "SCK 206 or 296" printed on it I need a little bit of advice on what replacement capacitors to buy, or if i should take them out of the circuit. I could leave them out, because they seem to hook up to a rectifier and then to a transistor, but i would rather buy the appropriate replacement capacitors. Thanks!

Hi there, I received a not-working air conditioner model DPAC12010H from someone who didn't need it anymore, and I took it to a friend who works with refrigerators to see if we could find the problem. We took it apart, and we found that a fuse mounted on the main PCB was shot. The fuse is 120V and 3.75A so I suppose it's only for the control circuit as the whole air conditioner runs at more than 9A on max capacity. Anyway, we temporarily bypassed the fuse with a copper wire to continue testing. We plugged it in, and immediately a component on the PCB (which I now believe is a ceramic capacitor) spew sparks and melted it's insulation. However after this incident the air conditioner works perfectly, and it blows very cool air (its a 12000 BTU machine after all). However I'm still concerned about that capacitor. I can not post a picture right now, maybe when I get back from work. It was brownish yellow, about 3/4" in diameter roughly same shape as a nickel. Does anyone have any idea what that capacitor might be for? Since the air conditioner is working now I'm guessing the sparks made it conductive, or maybe it's used for the dehumidifier which I have not tested. I will buy a new fuse today and see what happens. The air conditioner draws about 9 A at full operation. Any help would be greatly appreciated.

I have followed the evolution of the 3D printer and I can see its potential as a real tool for home use. Ceramic krafts have been a fairly easy home size cottage kraft for centuries. Now If you had a small kiln and you were able to model Items from house wares to mechanical parts to ceramic molds (ie Cookie or decrotive bread pans or a Ceramic motor block to an Air Motor). I thought if you Cure/ dry it (ceramic paste) as it was extruded on to the model with focused lasers (ready for deburing and then a bisque firing) as in using lasers for curing/ hardening of a polymer mediums. The variety of Ceramic Mediums/ materials that could be used to fuel a boon to the unemployed as a way to make money. Maybe printing out one use molds, to form cores to Graphite products that could be washed out after and have the mold material reused. If there was away for me to follow through with the possibilities. Extruding those oven cured clays, that could stretch its usefullness. I am trying to figure out a way to get out from under the pile and recycle as much as possible and use as many American made parts and electronics as I can. Graphite fiber empreganted ceramic material, is there such a product out there that could be utilized in 3D printed parts? Is there a Market for Products made of these types of materials? So many questions, so many possibilities.

Hey- I'm going to build some Arduino clones (as posted from http://fritzing.org/projects/barebones-arduino/ ) and was wondering if it would be better to use a crystal or a ceramic resonator. i will be ordering from Tayda Electronics (Ive ordered before, 10 days shipping for rock bottom prices, I'm ok with that) and the resonators and crystals are +-5c. difference, so I was wondering if I could use resonators, since they are a bit cheaper and I'm ordering a few (around 8). Which ones would be better? Also, does anyone know for the circuit from the above link would work with a 4.5v supply if I just left out the 5v regulator? Many thanks- Astroboy907

So I recently started looking into some of the 3d printing stuff as a way to make a number of laboratory items that are not easily had other ways. While 3D printing seems really promising, i'm noticing there's not alot of work being done on non-plastics. Are there resources out there for 3D printer enthusiasts who want to use metal or ceramics in there creation? Off the top of my head, i can think of a few ways that they could be encorporated into an existing 3d printer (metal and ceramic powders in a wax binder that can zapped with a laser to fuze it into place), but I'm only just barely getting into this and i'm really not looking to reinvent the wheel simply because i didn't know that it's already been done. If plastic went entirely by the wayside, pieces that could be cured in a conventional oven could be printed, but fully cured, ready to go products are sorta the point of a 3d printer.

I have a load of assorted ceramic capacitors. Can I create a capacitor bank to power a spark gap, and if so, how? Since it is voltage that matters for spark gaps, most of these capacitors have obscure codes on them, which I cannot find any information about on the internet, but some have voltages marked on then. I have 4 blue 2kV capacitors, 9 brown 1kV capacitors and 2 large, flat 1000V capacitors. Thanks in advance for any help!

I have a small, round piezoelectric ceramic sensor made from PZT (Lead Zirconate Titanate) material that I would like to try out to see how much mechanical force I need to apply to light a 5mm LED. The piezo ceramic has already been soldered with two wires (negative and positive). Nevertheless, I am completely new to creating circuits that involve a piezo ceramic. As a result, I have no idea whatsoever on how to properly connect the piezoelectric ceramic to the LED as to light it up. I have connected the two together before and applied force on the ceramic to see if it created some sort of charge, yet nothing occurred.

Hi there, I'm designing a vaping device which is Li-Ion battery powered and uses standard e-liquids (propylene glycol / vegetable glycol). The liquid would evaporate around 200 celsius and the heating element should attain this temperature within 1 second. Current methods use a coil with a liquid absorbing wire, which is not durable nor easy to reuse. I've been looking into ceramic heating elements but it's a forest of options out there, most of them becoming waaaaay to hot and/or needing a much higher voltage than a standaard Li-ion battery would provide at around 1100 Mah. So i've been thinking of building one, or having a prototype built for me. Problem is, i'm not 100% sure that a ceramic method would be the best way (so many options). Around the ceramic element (or on top if it is in disc form), i'd place a replaceable sock that can absorb the fluid and withstand excess heat (better than the standard kanthal / ekowool / etc.). This way the end user would only need to replace a sock after some time (for instance when changing fluids). It would also not burn and contaminate the liquid like current system do. Anybody have an idea? Regards, Bert

Question by buffysissy1 | last reply
I'm wanting to touch up some chips on ceramic tile which is on our sidewalk. The tile is different from the typical smooth gloss single color which you commonly see in bathrooms. This tile has a bit of a texture and some speckles. The texture (no doubt) is in place to keep you from killing yourself walking when it gets wet from rain etc... I was dreaming of using some sort of opaque paint marker(s) and a perhaps some sort of epoxy sealant. Maybe laying down some paint marker and then manually adding some speckles.... I'm using these terms loosely. Any suggestions? See picture of sample chip. I put a quarter in the picture to give you some sense of scale. You may notice some discoloration around the grout area - that's probably because I had just wiped the tile area clean with a wet paper towel.

I am trying to make a heating element that would only turn on once the element itself reaches a certain temperature. This element, possibly ceramic, would be dormant until it reached an internal temperature from an external source (liquid) of 100 deg F. Once it is triggered, it would produce heat to maintain the liquid at 100 deg F. Ive been trying to figure out the best way to do this and how much power would be required. Say the liquid, well go with water, was 12 fl oz. how would I build a circuit that can be sensing temperature without using power, and once it reaches the desired temp, turns on the heater until the temperature either goes too high or drops too low so that it is not trying to work too hard. Open to suggestions on heating element types or anything that could help with my project. Thanks in advance!

We have an entry way that leads right into the basement. Since we have occationally had water on the floor there we want to take up the carpet and install ceramic tile. It's a small area, only about 50 sq'. I found lots of information online about estimating materials but nothing about how much time to allow for this project. I'm an above average handyman. About how many hours should I expect this to take? I know there are several stages, how long do I need to wait between stages? 1) apply self leveling floor compound (how long for this to set before going to next stage)? 2) Apply mastic and lay down tiles (how long for this to set before going to next stage)? 3) grout tile lines (how long for this to set before going to next stage)? 4 seal grout lines (how long for this to set before going to next stage)?
