Question about casting patina/colored copper sheets

[grz5]

Hello,

I have a question that i was hoping someone could answer. I have seen people cast numerous things in clear acrylic to make stunning blanks and while cleaning out my project space I found a sample pack of 36gage patina copper sheets about 5"-7" in length and 5-7" in height

I was wondering if anyone ever has, or was willing to attempt to cast pen blanks using some of these sheets.

I have attached a link that shows the different color variations they sent me awhile back.

Looking forward to seeing everyone's replies.

Butch posted a pen a while back using the same or similar copper veneer that he cast.

You will have a seam with the veneer, but still a pretty cool look.

whats the best way to hide the seam?

You can't hide the seam. You can place the clip over part of it to help disguise it. The pattern won't match at the seam so it will stand out.

Looks like Butch hid his seam with reflected light :wink::biggrin:

The veneers are 36gage sheets (0.0067")
Here's a few Q&A's from they're sight. I'd be willing to send out a few of the sheets I have if the person would be willing to cast a blank or 2 for me. You can keep the rest of the sheet.

Q: How thick is the light copper, and can it be bent?
A: The light copper is a standard 5 mil, which is approximately 36 gauge. If you take a foot-long sheet of aluminum foil and fold it five times, you will have an idea of how thick a copper sheet is. A 3' by 4' sheet weighs 3 lbs. The copper can be folded easily by hand.
Q: What do you use to cut the light copper?
A: A standard pair of scissors will suffice. We use Fisker scissors that can be purchased at any home improvement center, Walmart, or fabric store. A sharp utility knife can also be used to cut our light copper (use a new blade).
Q: How do you adhere copper to a surface?
A: Our light copper can be applied to any surface using standard contact cement. Please note, your can might say "Do not to use on copper" you can disregard this as we have been using standard contact cement for nearly 15 years, including adhering copper to ceilings. For bar tops only, you can use Titebond II Premium Wood Glue which will allow you some dry time to move the copper around for aligning. Once adhered, you will need to apply pressure to the surface which can be done by laying down some heavy books throughout and allowing it to dry 24 hours.

What if to hide the seam you laid out the copper on the tubes Pre-patina. then use some mild acid like vinegar to speed up the Patina process. would that even out the patterns on the seam, hence hiding it a bit better?

Never worked with copper, so this was just a thought. could be way off.

soldering would likely burn off the patina.

The easiest way to hide the seam is to make it look more like a segmentation. Wrap the tube with the piece of copper, then glue a couple wood strips to the copper, making sure one is over the seam. Then cast. Should look pretty cool.

I was thinking that same thing this morning when I saw this:

Not exactly the same but the segmentation process is there.
