 Unique Equestrian Treasures

Design ideas are made into drawings or a favorite photo is used for reference. Each sketch is then constructed in wax by freehand. The wax-up goes through a series of steps to enclose it in a heat proof material. Next it is placed into a kiln to empty the mold of wax and burn it out clean. That mold is then filled with molten gold and allowed to cool. After cooling, the mold is broken open, the alloy cleaned and the article polished.

  

 1. After two dimensional sketches, each piece is meticulously created in wax in three dimensions . The article is viewed and corrected under microscope, for detail.


 2. Wax-ups are secured to a rubberized base which forms the in-gate for molten metal.




3.  A steel cylinder ring is securely placed onto the base for the next step.

 

4.  A high-heat material is mixed and poured into the casting ring, filled to the top, taking 1 hour to set.
 

5.  The wax burns out clean in a two-phase oven high-heat process. Now the empty mold is ready to receive the molten metal.
 

6.  The pre-weighed gold or silver is melted by torch. In its molten liquid state, the heated casting ring is placed in alignment; and a centrifugal casting takes place.

 

 

7.  The result is a (positive) duplication in metal which was previously composed of wax (negative, empty mold).

 

 

 

8.  The casting is then cleaned, the desired piece cut from the excess "button" and polished. The leftover metal is added to the next melt with a ratio of new metal for the subsequent casting process.



 

This process is repeated for each new creation. Once the cast piece has been accepted and approved, a duplication is made; and our production begins. The assembly of the designs combines specific colors of alloys. Beads or pearls are strung with 'Beadalon' [trade name- a very fine stainless steel wire twist with nylon coating; highly resistant to breakage, designed just for bead stringing]. Gems and findings merge Tempi into complimenting pieces, forming sets. To view our creations, please continue to Tempi Designs.
