Arts and Science class , Short video project. You will need green sand (casting sand ) for this project. silicone mold could be substituted. Kits are available on amazon.
High temp silicone is best and suitable for pewter casting. Much finer detail over green sand, and reusable many times, little or no cleanup. I actually hadn't even seen pewter be cast on sand or petrobond/delf clay before. Nice process for the master.
Thank you for a great video, I have been searching You Tube for ages trying to find one just like this. I do metal detecting and I am often left with lead that is nothing but scrap. I have started to melt the lead into ingot/bricks and wanted a way to make medals. Now thanks to your video I can. I know the lead is toxic but I am contacting the local museum to find a way of coating it when I am done, to make it safe to handle. I have a few ideas already.
Lead is not as dangerous as the media portrays it.there are some things you should know. Lead dust is the most common way of being contaminated.Ingestion is the main way your body absorbs the element.jewelry is forbidden to be made of lead.lead however can be handled safely with proper protocol.don't grind or sand.( use heat)wash hands immediately after working with lead.do not eat or drink while working.lead can be sealed with many types of paint or covering.experiment with different covering depending on the project.I think 5 minute epoxy will make a good covering. Once sealed the object relatively safe.children should never be exposed to any amount of lead.it attacks their nervous system. Adults not so much..do not burn lead!!!! Very bad even for adults.please be safe. Study about lead from Department of environmental protection.
Erik Johnsen Thank you for the information and warning, it is noted and will be acted upon. I was thinking of encasing lead musket balls from the English Civil war as souvenirs, in a resin which is clear and sets solid, thus making it safer to handle. But I will do my research first. Thanks.
After cutting the and sanding the edges take your coin and drop it in a vibrating tumbler like the use for ammo With crushed walnut shells and a good amount of nu finish car wax Turn on and check back in 24 hours. They come out beautiful and shiny
Silicone doesn't like the high heat of zinc or aluminum. There is a special low temperature pewter in combination with a special high temperature Silicone that will work in combination. As yet I don't recommend a beginner to even attempt it. The metal that can be easily resourced melts above 400*f The normally available Silicone breaks down around 300*f. Greensand is an ancient process that withstands all temperature. Easy to use but not as refined a casting as Silicone. It is best to purchase the appropriate pre made molds and ultra low temperature metal. Smiles
How soft is this metal? I've only had silver but I'm tired of spending a load of money if I can get something cheaper that looks pretty much the same.. I know it's a soft metal but does it dent or bend easily?
Lovely work. I supose it will darken very fast. Any finishing ideea? Like plating or so... I have a medalion of same material I think and is very grey now.
I think you need to add small trenches leading from the bottom of the casting image to the outside edge. This would exhale any potential air pockets as the metal is being poured That's what I've gathered from watching other videos anyway :P you should probably do some research of your own before taking my word xD
William Kent put a spur at the bottom to collect dirt. Add vents on top . One is to pour into. The other releases air and should become full when poured. Also check the temperature of the metal. It might need to be much higher for small chambers.
Now this is the kind of stuff I like seeing. Low cost casters makin awesome products...good job sir!
Nice Work !

Nice ideas and very informative! Thanks!
Glad I found your channel. I am looking into making site tokens for a SCA event. I have never done this but with this video I feel I can. Thanks!
I thoroughly enjoyed watching this, thank you!
Way to go! I especially like the hand cast aluminum frame!
I have been making them from wood as well and with great success . Smaller fast and accurate.

my new site is called VYZUN (Vision) it will have a catalog of links for many types of art related projects , SCA and Cosplay

dragonwyck121 Thank you I will head over to take a look at your new site.
Casting in resin is a perfect solution.happy casting. Erik

Great video mate. Would be better to make a silicon mould? U can reuse them cheers Graham.

@@dragonwyck121 cheers mate.
Pewter can be polished but it does tarnish quickly. Try applying clear acrylic spray. Or polish regularly
Pewter does not tarnish unless it contains lead.
i expected you to say, 'da bears!' any moment....
Do you use any kind of antiquing to blacken the details? I've seen it used a lot, just starting out myself.
fun video to watch. subscribed!
Wouldn't it have been easier to make the coin master out of polymer clay?
How soft is this metal? I've only had silver but I'm tired of spending a load of money if I can get something cheaper that looks pretty much the same.. I know it's a soft metal but does it dent or bend easily?
Pewter is soft but in a coin form very hard to dent
Lovely work. I supose it will darken very fast. Any finishing ideea? Like plating or so... I have a medalion of same material I think and is very grey now.
Kiwi Clear Paste Wax ?
@@iac4357 I think it is effective just for a little time. :(
Any suggestions for not getting air trapped in there? Seems to be a common problem of mine.

Gaming Chinchilla yeah I have tried those and sometimes they work and sometimes not. Maybe I'm not doing them right.

The ancient craftsmen did not have Dremel, but they could do incredible things. The medallion turned out to be just miserable.
Show YOUR work !
@@iac4357 I would show, but I lost my hands when the Americans bombed Baghdad. I'm not very good at working with my feet ((((
FIRST
I'll be making a MAD SCIENCE handbook with lots of cool ways to use products from LOWES.
