Why is greenish deposit is found on copper vessels in rainy season?
The greenish deposit on copper vessels in rainy season is likely to be a patina, which forms due to the reaction of copper with water and carbon dioxide in the air. This patina is primarily composed of copper carbonate and copper hydroxide. It is a natural process that occurs over time and actually helps protect the copper from further corrosion.

Why are copper caskets only offered in 32oz copper and not 48oz copper?
There have been also a few 64 oz copper caskets around (for example one by the former Chicago Casket Company). In addition to that, there were the copper deposit caskets in production until the end of the 1970s by the National Casket Company of Boston and by the Boyertown Burial Casket Company. These caskets can be compared to 96 oz sheet copper caskets. While solid copper caskets are welded (or soldered) from sheets of wrought copper, copper deposit caskets are made in a time consuming electrolytic process by which molecules of copper are deposit upon a casket form which usually consists of 48 oz (ounces per square foot) copper or bronze sheets. This provides the casket with extra strength and a very smooth and untarnished surface without welding seams or burns. Copper deposit caskets ususally have a wall thickness of 1/8" (3mm - about twice as thick as 48oz copper sheets) resulting in an empty weight of approximately 600 to 800 lbs, while solid copper caskets weigh between 200 and 300 lbs. The main reason for (currently) producing 32oz and 48oz copper caskets only is probably the more affordable price. At the end of the 1970s, the wholesale price of a copper deposit casket was between $ 5,000 and 6,000 (plus about 1,000 for an optional silver plated exterior), while 32 oz solid copper caskets were available from around $ 500 wholesale already. Thus, the price of a copper deposit casket was about a dozen times that of the lowest priced solid copper sheet casket.
Is there a difference in material and price between a solid copper casket and a copper deposit casket?
Yes, there is a difference, and it's a big one. Solid copper caskets are made from sheets of wrought copper which usually have a weight of 32 ounces per square foot (standard caskets) or 48 oz, in rare cases even 64 oz or more. The typical weight of a sheet copper casket is between 200 and 300 lbs. 32 oz solid copper caskets are available from $ 2,000 upwards (Online casket retailers). Copper deposit caskets are produced in a time consuming process in which molecules of copper are deposited upon a casket form (usually made of 48oz copper sheets). Copper deposit caskets weigh between 600 and 800 lbs because the typical thickness of their walls is about 1/8 of an inch (3 mm). The cost of copper deposit casket is so high that they were manufactured until the 1980s only (by the Boyertown Burial Casket Co. and by the National Casket Company of Boston). At that time, a copper deposit casket was about a dozen times more expensive than a standard 32oz solid copper casket. The optional silver plating of the exterior would add another 25% to the cost of the casket. This price was exceeded only by cast bronze caskets (weighing between 1,000 and 1,200 lbs), which in the 1970s were about three times more expensive than copper deposit caskets. As mentioned, copper deposit caskets are no longer in production. The closest modern equivalent probably would be the 300 lbs heavy 48oz thermo-deposited bronze casket called "Marquis", manufactured by the York-Hoover Company; the casket costs about ten times the price of a standard 32 oz bronze coffin. The most famous copper deposit caskets were made by the National Casket Company. These copper deposit caskets had no joints or welding seams nor did the attachments of the handles penetrate the casket walls. National seamless copper deposit casket were used for the funerals of President Franklin D. Roosevelt (# 21260 bronze plated), William Randolph Hearst (# 21200 as triple lid inner glass sealer), Elijah Muhammad (silver plated model # 21200 as glassless double lid sealer) Elvis Presley (# 21200) and Aaliyah Haughton (# 20761 ornamental corner design, silver plated). The Boyertown Burial Casket Company manufactured several copper deposit designs, for example a copper deposited bronze casket (model # 2471) which had a complete solid bronze inner casket inside of it. The casket had a triple lid (outer and middle metal lids and an inner glass lid); the weight was probably around 700 lbs.

Why was Elvis coffin made of copper and weighed 900 pounds?
Elvis was buried in the same type of casket as his mother 20 years before: in a National copper deposit casket. Copper deposit caskets are about three times as heavy as sheet copper casket. Elvis' sopper deposit casket had an empty weight between 600 and 800 lbs.
What is a copper deposit casket and what is a solid copper casket?
Copper deposit caskets are often described as "copper lined caskets" - a description which is misleading because it misses the big differences in production methods, weight and price of solid (sheet) copper caskets versus copper deposit caskets. Solid copper caskets are welded (or soldered) from sheets of wrought copper, while copper deposit caskets are made in a time consuming electrolytic process by which molecules of copper are deposit upon a casket form which usually consists of 48 oz (ounces per square foot) copper or bronze sheets. This provides the casket with extra strength and a very smooth and untarnished surface without welding seams or burns. Copper deposit caskets usually have a wall thickness of 1/8" (3mm - about twice as thick as 48oz copper sheets) resulting in an empty weight of approximately 600 to 800 lbs, while most solid copper caskets weigh between 200 and 300 lbs. In terms of prices, the difference is even bigger, although it is difficult to talk in current prices because copper deposit caskets were manufactured in the US until the end of the 1970s only.

What happens when iron nail are placed in copper sulphate solution?
the solution turns green and the nails develop a brown deposit which is copper. the iron displaces the copper in the copper sulphate solution. This is because iron is more reactive than copper.
