- Q:What is better a metal plate flat iron or a ceramic flat iron? Why?
- Ceramic, because metal plates take longer to heat up and damages more than ceramic
- Q:Fine ceramics do not break easily?
- However, the fragility of ceramic materials - brittleness has not been fundamentally solved. Fine ceramic powder particles is larger, micron (10 m), is still very fragile, a new preparation method of the ceramic powder particle processing to nanometer level (10 m), the ultrafine powder particles to produce ceramic materials, a new generation of nano ceramics, this is the third leap of ceramic materials. Nano ceramics have ductility, and some even appear superplasticity. Such as TiO2 ceramic synthesized at room temperature, it can bend, its plastic deformation of up to 100%, toughness is excellent. Therefore, people hope to develop nano technology to solve the brittleness of ceramic materials. Nano ceramic is called "twenty-first Century ceramics".
- Q:I got ceramic in my schedule and i was wondering what do you do there? and is it fun?
- Well, I didn't take ceramics until junior college, but--yes--it can be fun. Every high school does things differently, so I can't tell you for sure exactly what your class will be like. You will probably do both hand building and work on the potters' wheel. Maybe you will mix your own glazes from chemicals, but you will probably use pre-mixed glazes from jars. Probably the teacher, or the teacher's aide, will do the actual firing (in the kiln--a really hot oven that goes over 2000 degrees F) for you, but in some classes they teach students how to load and run the kilns. In order to have the most fun with the class, do the regular assignments, but also think ahead about what kinds of things that you'd like to make, and then ask the teacher to give you pointers on how to make whatever it is that you have in mind.
- Q:are they good?????? okay i don‘t want colors(i‘m 13) because well i like colors i just don‘t want people to really notice them though.i would like to have white rubber bands and white brackets(?) i don‘t have them yet but getting them in august or september . please share your comments.
- If ur system is not factory it may just be pressure building up in the res tank and spilling out of the over flow pipe but the should be coolant i. Ur system just check once a week
- Q:with full-ceramic crowns it is advised to use ceramic or fiber post systems instead of conventional alloy post so that the core won't reflect and cause problems with the coloring. The active post systems are way too economic but I think still golden color might be a problem. Is there a system that combined the advantages of active posts and ceramic posts? It is not necessarily to be on the market. I am asking for an assay.
- Just leave a day later or earlier. 600 miles is a 10 hour drive. Definitely doable in a day-especially if you have 1 driver. Also you don't need to start at 6 am - you can start at 9pm to avoid the weather. You can also stop halfway. Lots of options that don't involve tires/chains.
- Q:Can the ceramic dish be baked in the oven?
- Yes, as long as it is not with Phnom Penh (with gold or gold on the plate) or iron, it is better to use a white plate or glass plate
- Q:Do ceramic straightening irons ruin hair?
- Something else I would like to add. Sure, the heat can cause damage to your hair. There are some things that affect this that have not been mentioned yet: - the smoothness of the plates is important. Ceramic plates are thought to be the smoothest plates you can use. That helps minimize any damage due to 'friction'. At a microscopic scale, a rough hot surface is like a scouring pad on your hair. - the plates can have hot and cold spots. Again, usually not a problem with the higher end models but some cheap ones do not provide consistent heating. That can cause you to get poor results on the first pass. This means you normally will use 2 or more passes on the same section of hair which can excessively damage the hair - flat irons need to be cleaned regularly (especially if you use 'leave-in' conditioning products - not all types of hair can stand up to the heat of many hair straightners. If you have the budget, go for a model that has a variable heat control (Sedu or CHI Turbo for example). Fine or damaged hair needs lower heat settings than thick hair. - the amount you use it. Think about the fashion models you see on the run ways. They have to get about the most abuse on their hair than anyone else. If their hair can stand up to this over-use, I have to think, we can too by using our straighteners properly and getting one that promises professional results. If you plan to use it once in a blue moon, than I think any decent unit in your budget is fine
- Q:hey so I was thinking about starting up ceramic painting as a hobby (pretty sure thats what its called) My grandma did it and she‘s made some really beautiful things that have been around my dad‘s house for as long as I can remember. Anyways what I‘m talking about here is where you buy the plain white piece and then paint it yourself. My only question is what it really would take to start a hobby like this in terms of buying the paints and brushes and anything else you might need. and what are the kinds of paints you should be using and all that. it‘s always interested me and now that I‘m almost done with school i would have time to do it.
- This Site Might Help You. RE: What kind of wire do we use for mobile home to power pole? We are preparing to wire our mobile home. We need to know what gauge and type of wire we use to go from the house itself to the power pole please.
- Q:How is the quality of ceramics assessed?
- Quality assessment requires a standard, which involves many aspects of construction ceramics. Mainly to see your use, general construction ceramics are imitation of natural stone. So compare the physical parameters of the natural stone you want to imitate with the building ceramics you need. The physical parameters of the natural stone are better than those of the natural stone. General physical parameters such as hardness, wear resistance, weather resistance, gloss, water absorption, acid resistance, alkali resistance, etc...
- Q:What’s the difference between ceramic wool and rock wool?
- Rock wool and ceramic wool are all used for insulation and the main difference between them is the working temperature. Comparatively speaking, rock wool’s working temperature is 650℃, lower than that of ceramic wool, which can reach 1450℃. But the thermal conductivity of rock wool is lower than that of ceramic wool. So, rock wool is usually used for wall insulation, and ceramic wool can be used in high temperature environments of all kinds of furnaces.
