NEW! (Metal) Cross of Coronado - Progress Thread

I have to say... I don't think that if it was an actual cross made in the middle ages it would have resin inlay. So I guess I prefer a less prop accurate look as far as the blue inlay is concerned. Not sure what though. What about blue marble?:love

This is the actual prop from the screencaps that have been posted previously.
I'll be experimenting with a couple of different options for the blue enamel part, but it looks like dark blue resin will be the best option.
I can't use real glass enamel, since the cross will melt in the process of baking the enamel on, which needs really high temperatures to melt.:unsure

I have to say... I don't think if it was an actual cross made in the middle ages, it would be made out of pewter and gold-plated either!:p:lol

Plus, a piece of marble inlay that thin would be incredibly brittle...
 
I agree with Brenton. I don't think we should be going for historical accuracy rather than screen accuracy.

Sorry to ask. I have seen lost wax casting of brass, that's why I asked. I didn't know you couldn't use the same process with pewter. Lost wax casting of brass can also be gold plated afterward too.

No! As stated before, this is being cast in pewter and being gold-plated.
 
Sorry, but this prop IS considered a type of a "religious icon." Even if you don't like the word religion.

That's not quite what I said.

My real point is though, while one is entitled to believe in religion and have their own opinions about it, those who do not believe in religion (the concept, not the word) are equally entitled to their (differing) opinion. It is not fair to try to tell those who do not share one's religions views how to act or talk simply because said opinions conflict with your own personal beliefs and feelings.

Therefore, I respectfully request that you do not tell me how to talk and I won't tell you what I think of your religious beliefs. :)

All that being said, the work being done on this prop is nothing short of amazing!
 
I agree that everyone is entitled to their opinion, that's why I expressed mine. I am NOT telling people what they can or cannot say, just what they should maybe think about before it is said. I assume I too am entitled to my opinion? But let's not get distracted here. This is a VERY wonderful religious icon being made and not just a prop and it gives testimony of a wonderful messiah.
 
Would you guys quit talking about religion?:rolleyes
It just causes problems like politics...

As much as I like to get my prop replicas as close to as if it actually existed historically, screen accuracy always wins. Even if part of it has to be plastic.
 
No problem. So you didn't answer my question. Do you know if you can you only use lost wax casting on brass and not pewter? Are you familiar with lost wax casting?

I'm very familiar with lost wax casting, and it can get very expensive!:eek
I've approached foundry's with pieces similar to this cross and they seem to shy away from them, due to the detail that is involved. Not that they can't do it, but they not only have to mold them and make a wax positive, but then have to clean up the wax positive and repair and fill in all the air bubbles that got trapped in the details. A lot of work is involved and I would be afraid of them messing up the details while repairing the wax positives of this cross. Especially, when there are a lot of straight lines and smooth surfaces.
Plus, when you're casting in high-temp melt metals such as brass, copper, or bronze,... as they cool, they shrink by about 10% to 15%. So, then I would have to go back and start over and make another master that is 10 to 15% bigger to get the exact size to the original.
The nice thing about pewter and other low-melt metals, is that it barely shrinks at all.:cool:thumbsup
Pewter is poured into high-temp silicone molds or graphite spin-casting molds, not lost wax!
Lost Wax casting is for high-temp melt metals such as brass, bronze, copper, iron, and steel.
 
I wish I had your know how! Is it anything like this link?

Yep! That's exactly the process of lost wax casting. As you can see from the videos, the amount of work that is involved, and you can also imagine the costs as well.

Pewter casting stops at the silicone mold stage, where the silicone can take temperatures up to 650 degrees. Pewter melts at 450 degrees.
