There has never been a shortage of companies offering casting services in this vast world of ours.  Every reputable caster will start with pure metal and mix a variety of additional metals to create the alloys that the jewelry industry employs every day.  So why are there such differences?  Obviously there are differences in quality and, in many cases, price.
Since the raw material price is standardized across our globe and set by the metals market, why then do prices vary wildly between casters?  We can explore some of the differences by examining a few of the basics of the casting industry.

For the most part, casters still utilize the “lost wax” casting method which, incidentally, was invented some 900 years ago by an Italian Monk.  While there have been tremendous technological strides over the past few years, the basic process remains the same.  There are so many variables that can affect the results.  Professional casters strive to maintain a consistency in as many aspects of the process as possible.  Let us, for the sake of this discussion, assume that each and every casting professional start with clean, pure metal.  When mixing the alloy, they utilize the proper percentages and for each cast, re-cycle less than 40% of “previously cast metal”.  We will also presume that the machinery, crucibles and flasks are clean and in tip top working order.  For the sake of this dialogue, we can also assume that quality investment is mixed properly and the wax models are sprued correctly.  After the suitable burn out cycle, the results should be in.  Why then, are there obvious differences in the quality from one caster to another?

At Innovative CAD Technologies, we have studied the process and have concluded that much of the differences lie with the choice of alloys that are mixed to create the metals that are cast.  There are many companies offering alloys for sale, many good, many not so good and some exceptional.  After exhaustive research, we feel the very best company offering these alloys is ProGold.  This company, based in Italy, continues to lead the industry in research and development in new master alloys to mix with the pure metals.  Their commitment to quality and service closely resembles Innovative CAD Technologies quest for excellence.  While capable of manufacturing large batches of each particular alloy in a cycle, ProGold chooses to make their products in smaller quantities of around 25 Kg.  Their reasoning is quality control.  It is far easier to control and insure consistency in smaller batches than in mass quantities.  ProGold employs the newest and most advanced technological instruments to constantly test each run of material.  This amazing company is a scientific research center.  Their commitment to assuring the best possible result for casters is something to be very proud of.  Customer feedback is vital to their company and the technical assistance that they offer to the industry is unsurpassed.

This leaves us with an obvious answer to the question of why all metals are not created equally.  We feel that one  of the primary differences lies with the caster’s choice of  master alloy. Yes, ProGold’s alloy might be more expensive than other competitors, but surely the final outcome is the prime concern.  A casting with less porosity and a more homogeneous structure will ultimately save time and money.  Thus, one can easily see that, in some cases, the lowest price shouldn’t be the critical goal. When it comes to casting precious metals, consistency, quality and service trump price only concerns.  Please take a moment to visit the website of ProGold at and see the difference that attention to quality and service can make.

I have included some very interesting (or maybe not) technical information regarding the very metals that we, in the jewelry industry, work with everyday.  Take a moment to view this information on our website at There is a tab for technical information.  I would be most grateful if you took the time to peruse the article and if you would be so kind as to send back some feedback.  I am attempting to offer simplified explanations to complex issues each month.  See just how much of a science  the creation of alloys are.
