Because i don't know
Many companies make crystal pendants. Swarovski is the main company that makes crystal pendants while there are other smaller companies that make them too.
Chromiun is the primary metallic element added to steel to make stainless steel.
You make a prediction based on something you know. So I know that table salt is sodium chloride (2 atoms). Epsom Salt is Magnesium Sulfate (MgSO4) which is 6 atoms. If we assume that the crystals grow at the same rate (same number of molecules per minute), then my prediction would be the Magnesium Sulfate will make bigger crystal structure, because of the bigger molecules. So I would expect the Epsom Salts to grow much faster - maybe up to 3 times faster. That would be a hypothesis that is testable and measurable.
Stainless steel is commonly used to make cheese graters due to its durability, resistance to corrosion, and ease of cleaning. The sharp edges of the stainless steel make it ideal for grating various types of cheese.
It's not that only alum makes big crystals.. There are so many compounds that can make big crystals. Even Sodium Hydroxide makes very good and big crystals. For crystals you need a uniform arrangement of atoms in space. For big crystals all you need is patience. The slower is the crystallization process the bigger crystals are formed. What industries do is called seeding. They make a good concentrated solution of the compound whose crystals are needed and then they put a crystal of the same compound in the solution. The new crystals form and attach to the crystal making quick and big crystals.
Quenching steel involves rapidly cooling it to increase hardness, but this can make it too brittle. Tempering is a process where the hardened steel is heated to a specific temperature and then cooled slowly. This helps relieve internal stresses and makes the steel tougher and more ductile, balancing hardness with flexibility.
Iron is used to make steel by combining it with carbon. The addition of carbon alters the properties of iron, making steel stronger and more durable. Steel is a versatile material used in construction, manufacturing, and engineering due to its high strength and resistance to corrosion.
It all depends on how long you take to make it Remember to keep changing the water and adding salt Also, when the crystal gets bigger, make sure you get a bigger cup
Big crystals are obtained by a very slow crystallization from very concentrated sugar solutions.
yes
Alluminum teflon is tougher than most other teflon.
it depends on if it is intrusive or extrusive (intrusive is below the earth and extrusive is at or above the earth) intrusive has a bigger crystal because it takes time to cool down.
Density has more to do with the the carbon levels in the steel, grading the steel based on the make up determines cost price and use. Steel nails are often made from the worsed parts or slag from bigger batches, due to this, making them less dense by compairison. The range of raw materials by witch steel is made is quite astronomical with well over a thousand types of aluminium. as an example.
Rubbing salt on skin can make it tougher by drawing out moisture and causing irritation, which can lead to thicker skin over time.
Wristwatches are typically made from a variety of materials, including stainless steel, gold, titanium, and ceramics. The watch face is usually made of crystal, commonly mineral glass or sapphire crystal. The band can be made from materials such as leather, rubber, metal, or fabric.
Your hands will grow to a certain point. But beyond this you must work to make them thinker and tougher. What i would suggest is that you try to find muscle strengthening exercises to make them thicker.
Yes, melanin does make the skin tougher. One of the function of the melanin is to give the skin color. The levels of melanin depends with the amount of the sunlight exposure.
