Heating Ceramics?

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.

Ceramic Mold and Copper? Answered

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?

Spoon marks on ceramic mugs.? Answered

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?

What kind of bit do I use to drill ceramic? Answered

I bought a really nice vintage cigar ashtray at an estate sale and I want to use it as a soap dish in my shower. Since it fills up with water as  I shower I'd like to drill a hole or two in it to drain the water. The surface I would be drilling is only about 1/8 thick. Any suggestions on what kind of bit to use? I read that since it has a glaze I need a glass bit? Thanks.

A little help with identifying Ceramic Capacitors?

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!

Ceramic capacitor in air conditioner DPAC12010H

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.

Building a micro (ceramic) heating element for vaporizing e-liquid?

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

How should I make a right side wing using only the left side?

I have a little ceramic figurine. IT'S LEFT wing (opposite of one shown) is broken and has been lost. Now, I want to somehow use IT'S RIGHT wing (pictured) to make another left wing for it, through casting, molding, clay baking, using foam or whatever. I don't have access to anything high tech. Basically foam, clay, etc. but no molten metals or anything. Any ideas? I mean, it would seem simple enough to just make a mould with the existing wing and use it as a mold to make a new one, but the wings are obviously mirror images of each other, so not only are they on the opposite side, they're sort of reflected. Here is the wing I have, I need to create the other. Thanks,

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.

Is there a ceramic extruding head for a 3D printer application?

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.

Small heating element, possibly ceramic, to sense and maintain temperature.

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!

How to best touch up chipped ceramic tile on sidewalk? Answered

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.
