Weighing your waxes BEFORE metal casting? => 21 photos

  The following weights shown here are exact and not just random guesses. If you avoid the simple procedure of weighing your waxes, how do you know what any item will cost?

 You can see in this chart how the weights change with the carat of the gold and the metal that is used.

 Measurements must be exact when using your flask for casting.

 

 The weights must be 100% exact, even if the item is a single-link bracelet. All that the owner can do is multiply the required links.

 Without even a stone size chart, how would you know the total diamond weight or the costs involved?

  A wax (even with the sprue attached) needs to be weighed. The weight shown should be with 2 decimal places for accuracy. The weight is essential in determining the amount of metal used in the flow of metal for the casting process.

  A little figurine shown here weighs exactly 6.64 grams, but not 6.6 grams, as that's the reading on some less expensive scales.

  Here are a few other waxes that are being weighed.

 The metal insert was needed, as when the casting was completed, there was still an opportunity for a 'belt-buckle'.

 The solution for the casting is to weigh all the items and deduct the steel rod to arrive at the correct 'wax &metal' weight.

  Here is a great photo of a 'hand-held' diamond scale from the 1940s. Accuracy was not on the list, but only 'estimates' took centre stage.

  Which weight scale would you use?

  These numbers shown are used in carat weights.

  This scale has a limited weight tablet, and it only works with batteries.

 This silver disk is quite heavy at 73.6 grams. This particular scale shows DWT (pennyweight), Grams, and Ounces.
