For Marsalla: you can’t get just one.
Go to the first post in the thread for details.

For all the CuCu contingent (among which I include myself, thus far, tho’ I’m beginning to wonder):

If you’re serious about wanting to do patina on copper and willing and able to remove all the non-copper parts, look into jewelry supplies.
Teaching video here for example: http://www.riogrande.com/Content/patination-VID-psd?Pos=8

There are a whole lot of “Etsy” and “Instructables” ideas promoted, some of which may be good.
Others are likely to do surface damage and produce results that wear off in your hands, not always to good effect.

The jewelry approach — assuming you have an appropriate sealer — gives a whole range of colored patinas depending on which chemicals you use.
Some of them are quite toxic; be aware you will need to take the leftovers to a toxic waste collector in some cases. Don’t store them inside living space.

My goat was French Fried years ago. :slight_smile:

Acid rain, variables in the atmosphere affect the type of rainfall each area gets so it would also stand to reason that the effect of the rain on various substances would also be variable.

We typically only get around 26” rainfall annually and we have months and months of high heat weather, so perhaps our conditions are not favorable to the greening of copper. I HAVE seen a green growth between the fins on my Texas Poker, but it’s hanging around my neck and exposed to oils and salty sweat so that’s a different matter. I clean that stuff out when I see it, but have pretty much quit polishing the copper as it’s a fruitless venture. I keep it clean, other than that I don’t worry about it. The Titanium portions look the same as the day I got it nearly 3 years ago.

I don’t know exactly what coating they used on this Cu X5, but it is a plastic type material very similar to the Protecta-Clear I tried on my Texas Poker. It’s a thicker coating than I used, but it may have been applied differently, I don’t know. Any coating on metal will wear, even a PVD coating unless it’s a DLC or something of that nature. Bare copper is gorgeous, I love it right after it’s machined, but I still haven’t been able to figure out how to keep it that way.

I will most likely polish this one back up to a high gloss mirror finish and when I do I’ll take pictures and show that too. I did this heating in an effort to get it to harden and to burn off the remaining coating. I’m such a polish freak that it will no doubt be shiny and new again in no time. This aged look was not my goal and while I know it’s the natural way, I too think it’s on the ugly side and much prefer gleaming shiny copper. :slight_smile:

In the spirit of William Blake, who wrote

“The road of excess leads to the palace of wisdom”
and
“You never know what is enough until you know what is more than enough”

One way to protect bare copper —- gold plate it.

Often when putting gold plating on another metal, it gets copper plated first — copper being an intermediary between say brass alloys and gold.

A pure clean copper surface ought to take gold plating quite nicely, and stay shiny for a very long time.

Or wait a year or two and there are promises of sprayable glass, and plating with transparent diamond ….

I’m’a starting to think I may want to to change my SS/CU order to another Al instead.
All of the features (?) and none of the bling ….

That looks nice with all the grooves having the darker aged patina.

2326

Beautiful!

OMG!!

This will be my downfall. Please add me another…

  1. SS/Copper (SS/Cu) set.
  2. WW
  3. 1 set.

Please #321, if possible.

Thanks!

It looks incredible, all three ways.

2330

Is the thick(er) coating also applied on the inside?
What about the heat transfer between MCPCB and body, if the coating is also there?

2331

It looks like Olight now has

Raw Copper and Rose Gold PVDed lights (no price difference!) between the raw copper and copper with rose gold PVD application (not really plating)?

humm…?

2332

We could even go for a very red version?

From Wiki

Rose gold is a gold and copper alloy widely used for specialized jewelry. Rose gold, also known as pink gold and red gold, was popular in Russia at the beginning of the nineteenth century, and was also known as Russian gold although this term is now obsolete. Rose gold jewelry is becoming more popular in the 21st century and is commonly used for wedding rings, bracelets, and other jewelry.

Although the names are often used interchangeably, the difference between red, rose, and pink gold is the copper content: the higher the copper content, the stronger the red coloration. Pink gold uses the least copper, followed by rose gold, with red gold having the highest copper content. Examples of the common alloys for 18K rose gold, 18K red gold, and 18K pink gold:

18K Red gold: 75% gold, 25% copper

18K Rose gold: 75% gold, 22.25% copper, 2.75% silver

18K Pink gold: 75% gold, 20% copper, 5% silver

12K Red gold: 50% gold and 50% copper.

Like maybe the “12K Red gold: 50% gold and 50% copper” version. Still very coppery (is that a word?) and I think it will even darken over time(a bit).

During ancient times, due to impurities in the smelting process, gold frequently turned a reddish color. This is why many Greco-Roman texts, and even many texts from the Middle Ages, describe gold as “red”.[citation needed]

If you want to blacken the copper (perhaps to alternate with other patina colors) then you should expose the copper to H2S, Hydrogen Sulfide. It blackens most reactive metals like copper or silver and as a matter of fact it is toxic in enclosed areas, so be careful. One of the indicators for H2S poisoning is the coins in the victims pocket are black…

And here I was being all naive and shi#, I thought rose gold could only be found in the Black Hills. Maybe that’s the only place it can be found naturally occurring….

2337

Here are thoes darn French again:

“Black Hills gold jewelry is a type of jewelry manufactured in the Black Hills of South Dakota. It was first created in the 1870s during the Black Hills Gold Rush by a French goldsmith named Henri LeBeau, who is said to have dreamed about the design after passing out from thirst and starvation. Black Hills gold jewelry depicts leaves, grape clusters and vines, and is made with alloys of gold with standard yellow gold as well as green and pink gold. In 1980, the 8th Circuit affirmed an injunction ruling that if a manufacturer was to call its jewelry Black Hills Gold, then it must be made in the Black Hills. The state of South Dakota designated Black Hills gold as the official state jewelry in 1988.

The designs use grapes, grape leaves and grape stems and are easily recognizable for their distinctive colors. Silver is alloyed with the yellow gold to produce the green hue, and copper is alloyed with the yellow gold to make the red or pink gold. The jewelry was originally made with South Dakota-mined gold but in more recent years, since the closure of the Homestake Mine, the gold is sourced elsewhere.”

H2S is fatal in very low amounts.
You can’t rely on your sense of smell to protect you
“Exposure to lower concentrations can result in eye irritation, a sore throat and cough, nausea, shortness of breath, and fluid in the lungs (pulmonary edema)”

There are several much safer ways to blacken copper:

Method 1 uses hard boiled eggs.
Method 3: ” the slightly darker color of an American penny can be created with baking soda and water.”

2339

Cool Ronin! Thanks for digging that up, I never knew! I have some rose gold on my necklace pendant that I’ve worn for many years, always thought it was a natural occurrence from the Black Hills and therefore “special” (they charged me like it was special, anyway!)

See? Isn’t this the coolest forum on the planet! :slight_smile:

That copper S1 looks pretty awesome. Not quite as nice as Dale’s stripped-aged-polished X5, but still pretty nice. :slight_smile:
