why does copper look silver inside ,,well what i mean is like when i have a piece of copper plumber pipe and ill scratch it deep, the scratch its self looks kinds silver or chrome ,even when you scratch wire ,,why is that, if its a copper pipe shouldnt the scratch stay copper colored ------and why do some copper peices look dull & bumpy and others are smooth and shiny
your copper pipe isn't all copper. Copper is pretty expensive, not very tough and pretty heavy, it wouldn't make much sense making a plumbing pipe all out of copper. Your pipe will probably be some other metal like steel or so and then coated with copper, so that it doesn't corrode. Copper looks copper colored all the way through. I could imagine the opposite, if you have a piece of badly corroded copper, it will be pretty dark on the outside but when you scratch it, it will become very clear and bright copper color.
Copper pipe isn't pure copper. But copper, silver, and gold all reflect light so you see glare of light reflecting off of it. If its dull you need to polish it and remove the dirt and patina from it.
Well the copper pipes are shaped by man and such so they do add things to all products in factories, even if it is mainly copper. and as for the texture, it had to do with if it was smoothed down or not and how and such. Hope I helped! <3
