How easy is it to get poisoned from copper? In powdered form it is easily lethal if ingested, with similar consequences to that of arsenic. but what about water running through pipes? Does it spall off into the water as it passes though? It would seem that copper pipes that have oxidized inside must more readily spall the oxide into the water.The reason I ask- I‘d like to buy a vintage coffee grinder- but the hopper is copper, which is oxidized to almost green. My oily coffee beans would be in contact with this surface all the time. Does this pose a health hazard? Is it any less hazardous than non-oxidized copper?I drink a lot of coffee- and I am usually fairly committed to the household appliances I invest in- I don‘t want to wind up a mad hatter in a few years!
NO! you need transfer paper!
For the best answers, search on this site shorturl.im/axBsY Copper Sulphate is definately a poison, but funnilly enough is used in the most unexpected areas considering its toxicity! It can be used to plate metals with copper, as a fungicide or herbicide, or as a chemical test for water (the anhydrous form will absorb water, turning blue). Mixed with lime it is called Bordeaux mixture. It is also used in Fehling's solution and Benedict's solution to test for reducing sugars, which reduce the blue Cu2+aq ions to red copper(I) oxide. In addition, Copper (II) Sulphate is also used in Biuret solution to test for proteins. If proteins are present, a violet coloration is obtained. Still other uses include hair dyes and the processing of leather and textiles. Copper sulphate is also used to test blood for anemia. A drop of the patient's blood is dropped into a container of copper sulfate, if it sinks within a certain time, then the patient has sufficient hemoglobin levels and is not anemic. If the blood floats or sinks too slowly, then the patient is iron-deficient and may be anemic. In a flame test, copper ions emit a deep blue-green light, much more blue than the flame test for barium. Copper(II) sulphate is a desiccant. Copper sulphate is a commonly included chemical in children's chemistry sets and is often used in high school crystal growing and copper plating experiments. A very dilute solution of Copper sulphate is used to treat aquarium fish of various parasitic infections. However, as the copper ions are also highly toxic to the fish, care must be taken with the dosage.

EVERYTHING is poison, it's a question of quantity. Also there is some, however small, amount of everything in everything. Arsenic is present in water but at very low levels it is not a problem. Many poison metals are nutrients in small quantities. Take zinc, which is illegal for industries to discharge into the sewer but is used to prevent colds. Copper oxide does not spall and copper pipes are used just because they don’t corrode. Copper will normally dull (patina) and if it were bright that would indicate that some was being rubbed off in use. If the corrosion is green it’s not the oxide. I’d scrub it out and hen figure that anything left is going to stay there. Copper is often used in food contact applications such a candy making. Strohs beer (not made anymore) was advertised o be made in copper kettles and I understand it was about 6ppm copper. Most city sewer plants won’t let you discharge more than 1-2 ppm in the sewer! I drank a lot of Strohs and I’m not dead yet. I’m thinking alcohol and coffee aren’t good for us, so forget about a little copper. As for the Mad Hatter that was mercury from it being used as a preservative in the beaver fur used to make the hats. SOME mercury is in the water and air but again, how much makes ALL the difference.
