Figure melting point

Recommended Posts

I was wondering what kind of alloy the figures are made of. I want to have one coated in vantablack, but I don't know if they can withstand 300° temperatures unscathed. For those who don't know, this coating reflects virtually all light and makes anything appear 2D. Perfect for making shadow minis if this works.

They're made from a proprietary high-tin alloy. I don't know what the melting point is, but when you reach it, they're basically tin solder and will turn to puddles. My experience* has been that they're fine at 200-225, but I've never run the temp up higher than that.

 

* My experience is no guarantee of your future performance. If you try anything like that, you're on your own. Let us know what happens, though.

There is a video on YouTube where ReaperBryan takes a run through the casting process.  He may mention the temperature that the material melts at in that.  I would look it up for you but stupid work internet does not like the Tube of you.

I went to my pewter supplier and looked at all of the lead-free varieties available.  The lowest temp melting point listed was 466 deg F.  Versions with lead get down in the 350 deg F range, but that is no longer used in mini casting.  As long as you keep it under 350 deg F and use modern lead-free pewter, you should be fine.

 

That said, I'd still run a test on a sprue or other piece of scrap.

According to the Encyclopedia Internettica (Wikipedia), you need 400degrees C to deposit VantaBlack.

that's 752degrees F, so possibly a bit too high?

 

Leaded Pewter IS still in use some places, but not in the USA.

Prince August in the UK even sells casting tools and blocks of leaded pewter for home casting because of the lower temperature.

( Higher temp = requires more vents and also faster wear of the mould)

 

Also, VantaBlack does NOT reflect light. It's in fact the best material currently available to STOP reflections.

(up to 99.965% of the light is absorbed)

 

Where do you get the stuff anyways?

(There's export restrictions on it, and not exactly something you can find in a local paint store)

High lead content white metals are still used in figure casting in the US. (See Old Glory 15s, for instance.)

 

Reaper, to my knowledge, does not advertise its figures as "lead-free". Further, the last information I saw from Reaper employees is that Reaper's metal minis may contain a small percentage of lead.

I cannot give an official answer, but I know that Reaper miniatures meet or exceed the regulations for lead content in miniatures, which are highly regulated, for laws pertaining to all 50 states, the US federal government, Canada, and the EU.

 

Lead can be a scary and controversial subject, so to prevent misinformation, I am locking this thread until such time as an Official answer to the original question can be made by an authorized Reaper employee. I have messaged Reaperbryan, as I believe he is best suited to answer this question and allay your concerns.

 

Thank you for your understanding.

      This is another bogle for Monster Blood Tattoo though it happens to look a lot like an especially large werewolf.
       
      First the sculpt:  Although fur is often difficult to clean the parting line on this one was largely invisible to begin with.  
       
      Second the paint:  It lent itself to a simple drybrush, but I've gone for such dark colors it doesn't show up in the photo.
       
      Third the question:  I just glued it to a round base today and can't decide how I should finish the base.  It's going to be used in tabletop skirmish games so it doesn't need anything fancy.  I just can't decide between gluing on sand and little rocks, applying resin sand gel, or using Apoxie Sculpt to build up the circular base to the level of the stock base.  Opinions?  Pros & cons?

      This is one of my favourite minis and I have been working on it for awile. I hmmd and hawd about how to base it but finalluy decided to do a simple raised cork base.

      Ladless and Gentlemints, I've been kicking this idea around for a while now. And with the current isolation I think it's a great time. I propose a craft paint challenge. I have tons of great miniature paints from various brands, but for the sake of fun lets see what we can do with craft paints. This is my proposal. Grab a random miniature, Bones or otherwise, and ideally whatever craft  paints you have on hand (no going to the store for craft paints, this is to promote social distancing) and see what you can do. This will serve two purposes. It will be a fun way to throw some paint on a miniature, and hopefully we can also show a lot of people that while specialized paints are amazing, you can also get decent results on a budget. If you aren't into miniature painting, and still want to throw some craft paints on canvas or paper or whatever then that would be great as well.
       
      I encourage everyone who feels it to jump in on this. Also what do you think about #craftpaintchallenge for tagging. Please post results on here and other social media. Lets see how much love we can get, and how far this will go.
       
      Official/unofficial start date of 4/11. And lets go. Cheers.

      Hadn't painted metal in a while... it was refreshing!

      Painted up this cool dwarf.  Went for an icy look and I'm really happy with how he turned out.  Critiques and advice are always welcome!  Thanks in advance!
