r/Silvercasting

Im casting resin 3d prints for first time and im wondering about propper sprue placement on this ring, is there something that should be changed about sprues?

Im using Liqcreate Wax castable resin.

This was actually a challenging ring to make for me. Thoughts on how I can improve my results?

So through trolling eBay I came across a "reasonably" priced lot of scrap silver jewelry. So this became an intersection of two of my questionably beneficial, and definitely expensive hobbies. Those being metalcasting and stacking silver...
It said it was "Sterling" but I already knew that wasn't true, and sure enough every piece I tested came out at .800 or so purity (common silver jewelry level). But I still like the results. Total weight was just over 22oz.

• The Yes/No coin was a sand casting
• The coins across the top were two sided graphite molds from Ancient Foundry
• The cross was a graphite mold I found on Amazon.

For context both are pure silver and were cast into pre heated graphite molds. The one on the left was melted with mapgas while the one on the right was melted with propane. Anyone have any advice on how to achieve clean smooth shiny ripples on larger casts?

I mean who the hell doesn't love Alien...

The photos where its white is the raw cast results.

Good afternoon everyone,
This is a follow up attempt after using some recommendations from my previous post. Using a clean graphite crucible and nothing else but pure silver.

Pour info:
.999 silver -985c (using 100% pure silver crystal)
Flask temp -600c
Pulling 27-29in vacuum on flask at time of pour (gauge verified)

I have a propane torch pointed at the bowl of the mold as I pour, as well as map gas on the crucible. All pours happen quickly after crucible is removed from the furnace. I let the vacuum pump run for ~1min after the pour, then I shut it off as well as the propane torch at that time. I wait 14 minutes before flask quench and model removal.

When removing the plaster, these bubble areas are already shiny, leading me to think it’s likely an air pocket forming somehow? I’m unsure what would cause these pockets under such a heavy vacuum.

Thank you for all of the advice in the previous post, I know this is a likely problem I’m causing, but I’m self taught and struggling to identify this problem.

I am looking to buy a gift for a buddy who just finished his first deal after starting a company. He is an avid hunter.

I want to get him a .308 solid silver bullet and have it engraved. I found this on google. (See pic)
