According to the passage, how is glass that has cooled and become rigid different from most other rigid substances?(A) It has an interlocking crystal network.(B) It has an unusually low melting temperature.(C) It has varying physical properties.(D) It has a random molecular structure....
Adding lead oxide makes a fine crystal glass that can be cut more easily; highly prized cut lead crystal sparkles with color as it refracts (bends) the light passing through it. Some special types of glass are made by a different manufacturing process. Bulletproof glass is made from a ...
That white, crystal-like coating on the surface of soy wax is totally normal. It’s called frosting and it’s just part of soy’s natural charm. While you can’t always prevent it, pouring at a lower temperature (around 50°C–60°C) and cooling candles slowly at room temp can reduc...
Glass is a unique substance that makes up materials all around us. It is very useful because of all its special properties. Learn about glass and...
glass transitionpolydispersitymolecular-dynamic simulationsThis paper compares simulation and experiment to verify how a hard-sphere fluid is different from a suspension of hard-sphere colloids near the glass transition at 6% polydispersity. This is done by performing extensive molecular-dynamic simulations ...
Natural glasses: Obsidian is a natural glass formed during an eruption of silica-rich magma. Shown here are Apache tears, mahogany obsidian, and snowflake obsidian. Minerals Amazonite (a green variety of microcline feldspar) Beryl (the mineral of aquamarine, emerald, and heliodor) Chrysocolla (a...
Glass, for example, is transparent to all visible light. Translucent objects allow some light to travel through them. Materials like frosted glass and some
Is it safe to use compressed air to clean my monitor screen? Yes, compressed air is safe to use for removing dust from your monitor screen. However, hold the can upright and at least 6 inches away from the screen to avoid damage. ...
I left my crystal ball in my car! Yeah— Most people don’t like this question, because it’s pretty much impossible to answer accurately. But keep in mind that the interviewer is not looking for an accurate answer: They just want to know that you’re serious about your profession an...
Because of its lead content, crystal glassware is stronger, heavier, and smoother than standard glass. The quickest way to identify crystal is to examine its look and sound. When held up to the light, crystal should reflect light and cast soft prism-like rainbows. Tapping genuine crystal emits...
