What does a lime look like under a red light?
Under a red light, a lime would appear dark and almost black, as red light does not provide the necessary spectrum to reflect the green color of the lime. The lime's surface would absorb most of the red light, resulting in a lack of color perception.
How can limestone be converted into calcium oxide?
By heating it. CaCO3 -> CaO + CO2 this was achieved traditionally in a lime kiln. The product, CaO was called quick lime as it reacted vigourously with water to form calcium hydroxde, which in turn was called slaked lime.
Where can calcium oxide be found?
Calcium oxide, also known as quicklime, can be found in nature as the mineral lime. It is also produced by heating calcium carbonate (e.g. limestone) in a kiln to very high temperatures, resulting in the decomposition of the carbonate into calcium oxide and carbon dioxide. Calcium oxide is commonly used in various industries including construction, agriculture, and chemical manufacturing.
Why silver jewelry is tarnish with lime?
sterling silver is 97.5% pure silver and7.5 copper alloy. This copper alloy reacts to humid conditions and acidic skin by tarnishing (brown) and oxiding (black).Lime is very acidic fruit so copper in the silver is reacting to the acid in the lime and tarnishing or oxiding.Clean it as soon as possible with polishing cloth.
What elements are present in lime water?
Lime water is more properly known as calcium hydroxide solution. Calcium hydroxide is sparingly soluble in water. It has uses as 'lime wash' or 'water wash'.It is made from two compounds which are 'quick lime' and water,through the following reaction:CaO + H2O → Ca(OH)2Thus it contains Ca(OH)2 and water H2 O.----------------------------------------------------Lime water is made of the elementsCalcium (Ca)Carbon (C)Hydrogen (H)and Oxygen (O)

How hot can an average kiln get in Fahrenheit?
A average kiln can get very hot just about to 2000 degrees Fahrenheit. It can be that hot and it can not get any hotter, that is the limit and maximum heat.
What does the colour lime mean?
lime is known its a fruit its very sour!
Can one use a salt glaze as a wash what would happen when applied to bisque?
Salt glazes cannot be fired in an electic kiln because the salt vaporizes and corrodes the elements. If you are using a gas kiln or electric kiln, the salt glazes can be very attractive.
Why is it often necessary to use multiples and sub multiples of a standard unit?
It isn't technically necessary; it is used for convenience, to avoid using very small or very large numbers.
How much acid does a lime have?
The pH level of lime is about 2. This means that it is very acidic.
What is a sagger maker?
A Sagger Maker is a very old profession, and hails from Stoke on Trent, England, they made large oval clay pots called 'Saggers'. These were filled with pottery then loaded into a bottle kiln, when the kiln was full of saggers it would be sealed and fired. The sagger protected the fine china pottery from the fierce heat of the kiln during the firing process.

How can you measure the temperature in a kiln?
Temperatures in a kiln are generally measured in two ways: by a pyrometer or by a pyrometric cone. Pyrometers are electronic thermometers which read the temperature inside the kiln. Pyrometric cones are pieces of ceramic formulated to bend at specific temperatures in a kiln. Most potters use both methods of measuring temperature because the temperature at which clays and glazes fire is very critical.
What type of citrus fruit from Phoenix area would look like a large thick skinned orange but taste like a very sour lemon or lime?

What does sodium bicarbonate do in lotions?
