Thank you. Glad that you like them. An easy way to get to most of the KZfaq videos is where I have them listed in categories: gsegmedia.com/?page_id=4657

You are most welcome. Here is an easy way to find the videos that are most useful for you. gsegmedia.com/?page_id=4657

Thanks, never heard of it. Will pass along.

Try using a carburizing flame when annealing your copper. You will have carbon on the outside of the copper but unlike a oxidizing flame it won't oxidize the copper and ruin the surface finish

Element collection huh? How many elements do you have? :)

Pat, check this video out. After you watch the video you'll probably have more questions, so get back to me. kzfaq.info/get/bejne/adiqpqlyv8DPnY0.html

Depending on the strength of the acid. White Vinegar very mild will take some time to remove oxidization. Toilet bowl cleaner is very strong. Almost immediate results. Rubber glove, and safety glasses recommended. Maybe even a mask - very strong fumes. Rinse with water = stops the acid from working. Glad you like the videos.

Good question. I really don't know. Probably best to as a plumber or a chemist. Any time I use acids for cleaning, I make doubly sure I rinse thoroughly with water to neutralize.

Thanks Thomas, I'll check that out.

Thanks for the comment. If it is an expensive copper sculpture, I would have it professionally cleaned. Without actually seeing it I would be hesitant to offer any suggestions.

+Mark Peacock Note: I don't know what chemical the painter used to turn the copper green. You might start out with some of the milder acids, like white vinegar, toilet bowl cleaner etc. Be sure to wear safety goggles, rubber gloves and a long sleeve shirt. If it was normal oxidation, the acid will turn the copper pink. To get the shiny copper like the bottom of a Revere ware pan, you will need to wire brush or steel wool. Once you have the bright and shiny copper, you will need to treat it with something to prevent oxidization (tarnish). This is all just off the top of my head. You are probably better off checking with paint stores or shops that install copper guttering. You might also do some more research on KZfaq. Wish I could be more help, but this is a bit out of my line.

maybe a wax of some kind.

God to hear that it was helpful.

I'm looking to get a small oxy torch setup for annealing bronze... any suggestions for a brand/model and reputable supplier?

I've been using Victor Performer Torches since 1973. I've gone through four or five over that time. Other good names in torches are Smith and Harris. I've had good service and good prices from cyberweld.com and weldingsupply.com. Cyber weld usually offers free shipping. I use oxygen acetylene. For just annealing, you might want to consider propane/oxygen. However, I have no experience with oxygen/propane so you may want to do some research. Not sure what temperature you need. Acetylene is hotter than propane.

Well that's an excellent start... I'll do my research. Thanks again for the info!

Just saw your cymbals. Check out a rosebud torch tip. Allows for annealing large areas. I have one which I use for annealing larger sheets of copper. If you decide on one, be sure that it will fit the torch handle of the torch you purchase. The rosebud tip that i have will fit on one of my torches but not another.

It depends on what you want to do. If want to do brazing, people are having good luck with oxygen propane torches. If you are talking about the little propane tanks at discount stores, I doubt that they have enough heat to braze, You may be able to silver solder. I'd suggest going online and seeing what jewelers are using for a heat source.

Thanks for commenting.

Muriatic acid is strong and it has an immediate effect in cleaning copper and brass. I rarely use it, but when I do I only use it outside (Strong Fumes). For your own safety, follow the safety precautions on the container.

That is a problem. :} Actually you could paint on an acid solution, spray it off with a garden hose and then buff up with a automotive buffer.

@@897473 thank you for the advice, I hope to find a paint-on solution :)

Not sure of your question "is that acid proof"?

Thanks for your insights.

Thanks for commenting. I've never used that combination.

Muriatic Acid is strong. I'd suggest only using it after reading and following the directions. Safety is Key.

@@897473 yes i know, i do chemistry and stuff and i even know how to make hydrochloric acid from NaCl so ofcourse i know how to take safety precautions just saying

@@miguelchacon2717 Thanks for your insight. As I said somewhere in the description for that video: I've tried to keep this at mild acids. The white vinegar and toilet bowl cleaner are easily accessible. Sparex #2 is especially good and can be ordered online. I think these three are fairly safe if used with caution".

I couldn't find it in the US. Checked their KZfaq video. They do have a lot of products. Thanks for commenting

"We" do... :) I am not sure we sell it over there in the US.

I checked the video and i'm gonna buy a bottle of this. I'm a Tiffany stained glass designer and i wonder if it also works as a flux on copper foil for 60/40 solder. I'll give it a try. I think it will be great when i work with copper sculptures.

Lil'moon star , yes, it will also work as a flux. It is actually its main function, cleaning is a nice side effect.

I am on the french website but they only have 157, it seems they no longer carry 157 SCE, are you castolin related? I'm french.

yes i am thinking of drain cleaner
