Actually, it is not that new. PMC Pro\u2122 has been introduced by Mitsubishi in 2010, I bought it from Cool Tools<\/a><\/b> in 2011. PMC Pro\u2122 is an alloy of fine silver and copper. 90% silver, 10% copper. As a fan of “pure” fine silver I was a bit apprehensive about this new offering from Mitsubishi. Why should you use another – quite expensive per gram of pure silver – alloy, when cheap and strong sterling silver is widely available? Professional jewelry makers might have shrugged their shoulders: they were already sceptical about precious metal clay as such.
\nBut curiosity took over and I decided to give it a try.\u00a0 The next question was: for what kind of jewelry <\/b>is this material best suited? The formal-logical approach documented here <\/a><\/b>was very helpful. You should use PMC – Pro or any other kind – only WHERE its use is optimal and the material has a clear advantage over other materials.
\nCurrently there are quite a few Internet resources available about PMC Pro\u2122. After having read some tutorials, for instance, this article in Fusion, Journal of the International PMC guild<\/a><\/b> <\/span>and a very informative blog by Lora Hart Pro or Con?<\/a><\/b>, I decided to make up the following table:<\/p>\n

PMC Pro Constraints and Possibilities
\n<\/p>\n\n\n\n\n\n\n\n\n
\n
\u201c-\u201c Qualities<\/span><\/div>\n<\/td>\n
\n
Constraints<\/span><\/div>\n<\/td>\n
\n
\u201c+\u201d Qualities<\/span><\/div>\n<\/td>\n
\n
Possibilities<\/span><\/div>\n<\/td>\n<\/tr>\n
\n
20% shrinkage<\/span><\/div>\n<\/td>\n
\n
no large stones can be co-fired, tricky to estimate future bezel size<\/span><\/div>\n<\/td>\n
\n
good workability: does not dry up fast<\/span><\/div>\n<\/td>\n
\n
long working time, possible to re-knead several times<\/span><\/div>\n<\/td>\n<\/tr>\n
\n
low melt point (800C), no hard solder<\/b> can be used, no Oil Paste can be used for repairs!* Not true, read this blog<\/a><\/span><\/b><\/span><\/div>\n<\/td>\n
\n
impossible to make multi-component pieces which need step-by-step soldering (from hard to medium to easy), no designs with the risk of cracks, no large stones can be co-fired<\/span><\/div>\n<\/td>\n
\n
high tensile strength<\/span><\/div>\n<\/td>\n
\n
possible to make rings and (bangle) bracelets, also from one piece, with tiny elements which will not break<\/span><\/div>\n<\/td>\n<\/tr>\n
\n
complicated firing procedure (carbon firing needed)<\/span><\/div>\n<\/td>\n
\n
when using combustible components, careful planning of the firing procedure is needed<\/span><\/div>\n<\/td>\n
\n
very flexible, high plasticity<\/span><\/div>\n<\/td>\n
\n
possible to make sophisticated sculptures<\/span><\/div>\n<\/td>\n<\/tr>\n
\n
does not blend with other PMC<\/span><\/div>\n<\/td>\n
\n
combined pieces not recommended<\/span><\/div>\n<\/td>\n
\n
easy to attach fresh Pro to fired Pro with homemade slip (add some lavender oil to the slip)<\/span>* Not true, read this blog<\/a><\/span><\/b><\/span><\/div>\n<\/td>\n
\n
possible to make multi-element pieces without Oil Paste<\/span><\/div>\n<\/td>\n<\/tr>\n
\n
dedicated tools needed<\/span><\/div>\n<\/td>\n
\n
buy new toolkit, make a series with PMC Pro only<\/span><\/div>\n<\/td>\n
<\/td>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n<\/div>\n

<\/div>\n
\"\"<\/a>My logical conclusion was: make rings and\/or bracelets without stones or just with very small stones, combine elements step-by-step, take your time between each step to think about the design and further procedure, read firing instructions carefully, avoid too complicated designs, especially at the beginning.<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n
\"\"<\/a><\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n
After having defined this strategy, I opened the pack. My first impression was: a chewing gum – very flexible, viscous, dense. Does not dry quickly, takes some time to blend with water. Sticky stuff, you should really use plenty of oil or other gunk on the roller and on the teflon foil. The fingers get dirty. Really dirty, as the color is dark grey – much darker than the color of PMC 3. On the bright side: very malleable, sculpturing is great, clay shapers are much more useful than with PMC3, where the main shaping job is done on the greenware.<\/div>\n
So these are my first PMC Pro\u2122 pieces – future rings. I will describe here the further working process and my experiences.<\/div>\n
