## Questions & Answers

**Q: Can I use this to cast charms or is it to soft?**
A: No, it's good for charms, as long as they are not too long and thin (easily bent). Try not to heat this stuff in your good stainless pot. It will ruin the finish. Also, don't get it near gold or silver jewelry for the same reason. I used a silicone cupcake mold to melt mine in. Put in into a shallow frying pan with water in in and wait a few minutes.

**Q: This is what pulled when I searched for Cerrosafe. Is this the same thing?**
A: No. This is a completely different alloy than Cerrosafe. It has a different melting temperature (Cerrosafe is 165ºF), and different shrinkage properties. Cerrosafe shrinks when it solidifies then returns to exact size when it cools, which is why gunsmiths use it. This stuff expands very slightly and stays that way.  Don't buy this if you want Cerrosafe. https://en.wikipedia.org/wiki/Field%27s_metal

**Q: What is the percent of Cadmium  and Lead?**
A: High enough to be dangerous if inhaled in large quantities. Woods metal has upwards of 27% lead and 10% cadmium. Best non toxic substitute is called fields metal

**Q: is it eutectic alloy?**
A: Only the manufacturer of the alloy can say for certain but I suspect not since it seems to have a softening range around 158 degrees F; but, so far as I can tell, not a well defined melting point.

    Contains some lead, so don't eat this!
  

*by J***. on Reviewed in the United States on April 11, 2014*

I carved a wax heart, embedded it in plaster of paris, put the casting in the microwave to get the wax out, then poured this metal into the sprue hole. Voila! Instant metal heart! My 7 year old daughter was impressed so much that she didn't even realize she had learned how to do lost wax casting. I had fun also. This stuff melts at 158 degrees F, so is easy to work with and not dangerous at all (does contain lead, so wash hands and don't chew on it). One nasty problem is that it will attack all but the best stainless steels, possibly even gold or silver jewelry, so be careful! There  is a more expensive version that contains no lead and I think melts even lower. maybe I'll get some and experiment.
