My coffee mug is made from a ceramic material.

Foam cups contain air pockets, and this makes them better insulators. Heat travels by conduction, convection or radiation. \n\n1. Conduction\n\nThe air pockets drastically reduce the heat transmission by conduction. Heat travels more easily through the ceramic by conduction than it does through the foam with the air pockets. \n\n2. Convection\n\nSince ceramic contains few if any interstices; so there is definitely less air in ceramic than there is in the foam. However, in both cases, the air pockets are very small, limiting the amount of heat that can be transmitting by conduction. \n\n3. Radiation\n\nInfrared radiation is probably passed more easily through ceramic than foam, especially given the color of most foam, which tends to make it quite reflective. \n\nA quick way to tell how insulating they are is to feel the foam and the ceramic with your hand, to determine which feels cool to the touch and which feels warm. The foam definitely feels warmer, since it reflects the heat back from your hand. The ceramic will likely feel cooler to the touch, and therefore it is not as good at insulating.

CLAY- Earth material, chiefly made up of Al2 O3.2SiO2.2H2O,(Aluminium oxide/silicon dioxide/hydrogen oxide ?) forming a paste when wet but turning very hard under the operation of heat.\nSAND- Loose material formed of small but clearly separate round grains, chiefly of QUARTZ, from about 0.1 to 1 mm, across, produced by the rubbing away of solid stone, and put down in stretches by water or formed into masses by wind.

Solid and in solids Diamond.\n\nSecond  Alummina and titanium carbide.

styrofoam i guess. \nlose three fingers?....ouch-ouch and ouch.

A Thermal Interface Material (aka TIM) is used to fill the gaps between thermal transfer surfaces, such as between microprocessors and heatsinks, in order to increase thermal transfer efficiency. These gaps are normally filled with air which is a very poor conductor.\n\nThey take many forms. The most common is the white-colored paste or thermal grease, typically silicone oil filled with aluminum oxide, zinc oxide, or boron nitride. Some brands of thermal interfaces (notably Arctic Silver) use micronized or pulverized silver.\n\nAnother type of TIM are the phase-change materials. These are solid at room temperature but liquefy and behave like grease at operating temperatures. They are easy to handle and are not messy.

The solid phase.  Water is an exception.\nAlso some materials has more than one solid phase, such as carbon which has different structures and therefore different densities for graphic as opposed to diamond.

styrofoam because it is a better insulator of heat than the other materials mentioned\n\nyou do not have to be a physician to know that

It's a material with at least two constituent parts - i.e. made up of a metal (e.g. aluminium) and some other material like a ceramic.\n\nThe composite is such that the matrix constituent reaches throughout the whole material - so it's not just like two materials glued together. The second constituent, which is also called the reinforcement, 'wraps around' the matrix and can also protect it from weathering damage, fatigue etc.\n\nA good example is TANK ARMOR.

Copper. Or if you mean electronics (not electrical), it would be silicon (otherwise known as sand).

Mostly quartz and orthoclase feldspar. Any number of other minerals can make up the rest.

I am a ceramist.  Porcelain clay is hardened and made permanent by firing in a kiln at temperatures of between about 1200 degrees Celsius and about 1400 degrees Celsius. The toughness, strength and translucence of porcelain arises mainly from the formation at high temperatures within the clay body of the mineral mullite and GLASS.  \n\nThe side and rear car windows are made of tempered glass.  The glass is heated (at lower temperatures than required to make porcelain), then rapidly cooled. This "tempering" process makes the glass many times stronger than un-tempered glass of the same thickness.  Upon impact, tempered glass is designed to disintegrate into small pieces of glass about the size of rock salt. \n\nSince porcelain is heated at a higher temperature than auto glass, the harder porcelain will easily break auto glass.

the common name for that is pewter. it's a cheap material for things like silverware.

Ceramic tile is pretty durable.  Cooler climates can make it more brittle, and it can break or chip if you have something heavy.  Porcelain is more prone to breakage until it is laid down, and then it is stronger than ceramic.  Other benfit is porcelain is the same color througout, while ceramic is terra-cotta color with a thin layer of enamel on top.

lots of materials' properties can be found. you can try this link..

I'm not familiar with this material, but sometimes websites that give info on materials and compounds include IR-specs.  Or, if you have a sample, call your local university.  Some one may be able to help you there.
