<p>[QUOTE=&quot;desertgem, post: 2565702, member: 15199&quot;]You didn&#039;t say what type/size of objects you were concerned about. The rare earth magnet effect is very difficult to differentiate, unless it is something like a flat full silver object. Paramagnetism is known and can show easily in carefully done experiments, but,&nbsp; with only subjective input by the experimenter ( usually the owner can see it well) ,it is hazy. People easily &#039;see&#039; it if they know something about the object such as its an ASE or a brand name bar than an unmarked one. The Ice-cube method is also based on properties of silver, but even 50% silver will be faster than base metals alloys, but slower than pure. When we do thermodynamics of solids in chem experiments, to identify properties or mix of metals, the answers from beginners are all over the scale at first but get better over time. It would be even worse if they just used an ice cube with no other measurable restrictions, such as was the ice cube made from degassed water or did it have bubbles within, was the ambient temperature exactly the same for both samples, etc. That is why the sources do not say , ..it will melt 22% faster or anything, just &#039;faster&#039;.</p><p><br /></p><p>In summary they could work, but I myself would not base any outcome such as buying or trading on it, unless lab conditions were used, and time is more important for me.
