Ceramic is a poor conductor, therefore it is an insulator!  It will keep your coffee hot longer.  Tin is a good conducter, so it will let your coffee cool faster.

If we put two smooth glasses together (without glue them), normally what is the distance in between? \nIn an ideal situation, let's say the two glass surfaces are perfectly smooth and 100% flat, and we superpose one of them onto the other, there should be an uniform distributed air-layer between the two pieces of glasses even though it looks we put them in direct contact, so what is the thickness of this air strip? round 10nm? or more than 1 μm?\nAny guess is welcomed :)\n\n\nif ur mentioning that it is an ideal situation - glass 100% smooth etc. then it is stupid of u to ask such a question. \n\nThere wud b no air gap b/w them.\n\n(ur quest included so u may not modify it later)\n\n\nArchitectural glass is made from three principal raw materials, easily found in nature: silica, lime and sodium carbonate.\nAvg size of molecular terrain would be approximately 300 - 3000A. (neglecting secondary composition of glass). Thus logically this has to be the thickness of this strip of air.

at the market?  so you mean a food product? or some type of hardware/metal?  a can or glass jar?  I'm trying to understand blindly here?  give me some more info so I can help you more. (I also must convert your temperatures) but be as specific about what materials you refer to please? email yahoo aplacefortess or addme to live chat. good luck

Streak, I would say, based on the following:\n\nPhysical properties commonly used are :\n\nCrystal structure and habit: A mineral may show good crystal habit or form, or it may be massive, granular or compact with only microscopically visible crystals. \nHardness: the physical hardness of a mineral is usually measured according to the Mohs scale of mineral hardness. \nLuster indicates the way a mineral's surface interacts with light and can range from dull to glassy (vitreous).\nStreak refers to the color of the powder a mineral leaves after rubbing it on an unglazed porcelain streak plate.\nCleavage describes the way a mineral may come apart or cleave in different ways. In thin section, cleavage is visible as thin parallel lines across a mineral.

grade five is the highest grade (more perfect in roundness and quality).  ceramic is harder than steel and roll smoother and wear slower.  it costs more, but worth the price, unless you pack your hubs frequently.

Have you thought about making your own? Instead of looking for an already made plate to embellish see if there is a ceramic/craft store in your city. It's fun as well as addicting and you will have glazed a one of a kind piece.

CaO + H2O => Ca(OH)2\n\ncalcium oxide + water => calcium hydroxide\n\nThis is a great site for this - the reaction between CaO and water is an exothermic reaction (1)\n\nthe second reference is even better - not simply a diagram but a torn apart "self-heating" can\n\ngood luck!\n\nSomething else you might want to looking - MRE's (meals ready to eat)

Generally speaking if you mixed the GERU completely with your usual clay, it is coloring.  A top coating would be considered as glazing by most (and for terracotta, the color must extend throughout and not just be on the surface).\n\nMost stoneware is made entirely of Geru clay.  This is part of the expense of making the items.

it really depends on the type of cookware and what it is used for... for some pieces anodized aluminum is far superior... for others stainless with aluminum clad bottoms... and still for others, like dutch ovens, cast iron is the way to go... for a little guidance, do a google search for Alton Brown and his book Gear for your Kitchen... it goes into some good detail on what's good and what's ok... he also has a sense of humor too... check it out...
