To read a half hallmark on the bottom of a copper kettle, first, ensure good lighting and use a magnifying glass if needed. The hallmark typically includes a series of symbols or letters indicating the maker, purity, and origin. If it's partially obscured, focus on any visible parts of the symbols and consult reference materials or online databases specific to copper hallmarks for more context. If necessary, consider reaching out to an appraiser or antiques expert for assistance.
What else can I help you with?
Does a kettle use more power if its half full?
yes
Why does half a full kettle take less time to boil a full one?
That is not possible a full kettle has more water,therefore it will take longer to boil.
When was The Bottom Half created?
The Bottom Half was created on 2007-04-03.
What is the half equation for the reduction of copper oxide carbon?
The half equation for the reduction of copper oxide by carbon is: CuO + C -> Cu + CO
What elements are in a half dollar?
Copper and nickel.
What a half dollar is made of?
Since 1971, U.S. half dollars have been made of nickel-coated copper (91.67% copper and 8.33% nickel).
What animal is the bottom half of the Sphinx?
If your talking about Theinen the Great Sphinx, the bottom half is Sphinx Teleia and the top half is Andro Sphinx.
What element has half as many protons zinc?
The element that has half as many protons as zinc would be copper. Zinc has 30 protons, while copper has 29 protons. This means that copper has one less proton than zinc, making it the element with half as many protons.
What is the metal makeup of a half dollar?
Current half dollars are made copper and nickel.
What is the composition of dimes quarters and half dollars?
Since 1965 for dimes and quarters, and 1971 for half dollars, the metal composition is 91.67% copper with 8.33% nickel. Each outer layer is 75% copper/25% nickel, over a solid copper core.
Is a piece of copper cut in half a physical or chemical change?
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
What are the half equations for purifying copper?
I will use an electrolysis example to possibly give you a better understanding. This is a copper half equation. The main points of half equations are: Metals are always positively charged and non metals are negative. When the two come together, they will form an ionic bond, by on donating electrons to the other to form a complete outer shell, this should not be confused with covalent bonding. In electrolysis, the purifying of copper takes place at the negative electrode, or the 'cathode'. Now finally for the half equation :) : Cu2+ + 2e- -> Cu The first part is the positively charged but impure copper. The second part is the number of electrons which displace the impurities, which will often form a sludge at the bottom of the container this experiment is done in. The last part is the final part of the equation, the pure copper. I hope that this mad sense and that i did not blabble needlessly.
