Robert Lopez | Bridging the Gap Cuff | Tuesday, February 5 and Wednesday, February 6, 2019 | 9 am until 4 pm


Two day workshop to include:

Heat treating titanium to obtain an attractive and durable crystalline structure. The heat treatment can achieve vibrant colors including gold, magenta, purples and blues.  We will be using a special resist to achieve unique color patterning on titanium.  Robert will be introducing students to his heat resist used to control color patterning.

Roller printing a pattern on the titanium & Argentium Silver to give it more texture.

Argentium Sterling Silver: We will cover the benefits of working with tarnish resistant Argentium Sterling Silver. Argentium is a silver alloy that is whiter and brighter than traditional sterling and can be annealed softer and hardened beyond traditional sterling.  We will be fusing Argentium silver granules, water casts, wire and square silver bits enabling us to cut back on solder joints.

Water casting.  A demonstration will be provided.  Students may participate depending on time constraints  To be determined at instructor’s discretion.

Bezel setting. I will also instruct students on the process and benefits of constructing a thick wall bezel with notches for setting a cabochon. We will be setting two colorful cabochons. Robert will offer several types of stones for students to choose from; some typical cut stones and some natural surface minerals.

Granulation. Melting silver into balls used to bridge gaps with fusing techniques.

Riveting.  Students will be using Roberts “Stinger Riveting System” to make quick and flawless rivets that will join silver and titanium. We will riveting two separate sheets roller printed and heat colored titanium to a sheet of Argentium to bridge the gap between, creating one mega cuff full of colors, texture and free-flowing organic energy.

Patina & Polishing. Students will have the option of adding a colorful patina or a bright shiny polish to the silver to add an extra layer of Wow!

The workshop will also cover texturing, soldering, patina, forming, filing, sanding, shaping and finishing.
