✦ABOUT THE ARTIST✦

Molecular Motifs is a culmination of my love for science, art and metalsmithing. I am a certified Art and Special Education teacher and have my B.F.A. in Mixed Media and Studio Art. After teaching for nearly a decade, I decided to make my passion of making jewelry, specifically science themed jewelry, my full-time career. I absolutely love turning an abstract idea into something we can see, feel and wear! The teacher in me also finds a lot of joy in knowing that my creations open up a dialogue and give the wearer an opportunity to teach people about their jewelry.

Thanks for stopping by, and I hope to have the opportunity to create something special for you!

✦ HOW IT'S MADE ✦

♻️ Made from Recycled Sterling Silver♻️

First and foremost, I do an extensive amount of research to both understand what I am making and to ensure that the design is accurate. This is extremely important when making molecular structures and other S.T.E.M. related designs.

Next, a computerized image of the design is made and used to create a 3D printed wax model.

The wax model is used to create a mold that is used for casting metal. This process is known as The Lost Wax Method of casting.

The wax is placed inside a steel cylinder. The cylinder is filled with an investment mold material that resembles plaster. After the investment properly sets, the cylinder is placed into a kiln and is brought up to 1,310 degrees in order to burn out the wax (hence the term Lost Wax).

After the wax melts out, the cylinder is removed from the kiln and placed on a vacuum table machine to get all traces of moisture & air bubbles out. Then, molten metal is poured into the mold to replace the space where the wax once was. When the newly cast piece is slightly cool, it is quenched in water so the investment returns to a clay-like state and is easily removed from the newly cast pieces.

Each piece is polished to a brilliant silver shine!

My creations are made from recycled metals that otherwise would have been tossed away; instead it's melted down and turned it into something new and unique! This allows me to be environmentally friendly and bring my customers affordable, high quality, competitively priced, handmade jewelry.
