Cost: $250. (plus a $30 materials fee)

In this one day intensive workshop participants will learn some German Goldsmithing and other tips and techniques to simplify some of the challenging styles of diamond and fine gemstone setting. These techniques have been developed over 26 years of studio practice. By understanding and practicing these basic principals, you will be able to utilize the methods to further your own jewelry techniques and adapt them to your own design work. Settings that will be covered will include: Tube setting, Flush Setting, and a Tapered Bezel Setting (fabricated bezel).

Much of this workshop practice will be done on actual pieces, not just flat demo surfaces, which is better training for the real thing. This is training for both students and professionals. Need a diamond accent on your pendant? Your own pieces are welcome for flush and tube setting. Bring your magnifiers and loupes, these diamonds are tiny!

Chasing and Repoussee with Davide Bigazzi!
In this three day workshop participants will learn an understanding and utilize the plasticity of metal to shape and raise rich and fluid forms and textures. Each student will design and create their own chased and repoussed bracelet. Immerse yourself in metal with demonstrations & discussions on chasing tools, pitch, patina, & much more. All with an Italian cultural and historical perspective.The main focus of this workshop is the creation of a cuff bracelet by employing chasing, repoussé, forging, & soldering. Learn how to add rich textures and sculptural form to your jewelry. Cost: $1150

Davide Bigazzi’s handcrafted jewelry and hollowware are a blend of contemporary artistry and old world craftsmanship that echoes back to his native Florence, Italy. Davide is renowned for his mastery of chasing and repoussè, the ancient art of shaping and embellishing metal with raised bas-relief designs. Davide was classically trained as an apprentice in Florence and earned his craftsmanship.

Scultpural Wax Bracelet with Shana Kroiz June 22-24, 2017
In this three day workshop participants will learn to carve a sculptural bracelet out of hard wax. Then students will learn to build a hinge and a box clasp out of wax. This will include the use of traditional carving techniques as well as carving with a flex shaft and engraving tools. The mechanisms will be made by milling and using the flex shaft as a lathe. We will also explore stone setting techniques in wax. Participants will send their bracelets to be cast after workshop is over.



April 8-10, 2016- Fold Forming With Charles Lewton-Brain!
This workshop delivers the whole system of hundreds of folds in three days. You will learn to make folds in each of the main categories. Forms are derived from the natural plasticity and ductility of the metal. Shaping is extremely effcient and rapid – many forms are complete in three to seven minutes. Tools are simple: fingers, hammer, anvil and mill. Complex relief forms are made from sheets of metal often in one annealing. Forms made with this method resemble chased constructed and soldered forms and can be made with most metals, including steel.
Charles Lewton-Brain invented fold-forming, a completely new way of forming sheet metal quickly into wonderful 3-D shapes and textures, most from single sheets of metal without any soldering.

Anticlastic Raising with Michael Good October 8-10, 2014
We are thrilled to be hosting Micahel Good at Cogent Builders Studio!!! Anticlastic Raising is a technique of metal forming whereby sheet metal is formed directly with a hammer on a sinusodial (snake-like) stake. A flat sheet of metal is shaped by compressing it's edges and stretching the center so that the surface develops two curves at right angles to each other. The pattern of the sheet plays a major role in the form that will be achieved, however, many different forms can often be made from the same pattern.
••Stay in touch, because we are hoping to get Michael back in 2016

Workshop Descriptions


Pewtersmithing Workshop

Pewter, made up of antimony, copper, and tin is one of the most mysterious of the non-ferous metals. Due to it's very low melting temperature and high malleability it can be moved faster and in different ways than other metals. Because of it's uniqueness, it is taught much less frequently in our metalsmithing community. In this 3 day workshop, you will learn how to use pewter's uniqueness to your advantage. You will form metal using fusing, hammering, and scraping techniques. You will learn how to solder pewter along with different finishing techniques.

Hydraulic Press Workshop

A hydraulic press is a metal frame that holds a hydraulic jack. The force of the jack allows the user to apply extreme pressure, pushing metal through a die. This creates a pillowed form with little stress to the metal. This is a very exciting way of moving the metal without using hammers and stakes, marring the surface of the metal, or spending a lot of time. It is an essential technique for production artists to be able to make 3-dimensional forms in little time and with few tools. This technique is great for all ages and skill levels of Metalsmiths and jewelers. It is not a technique that requires a lot of strength or endurance and it does not have the stress on your joints and muscles that other forming techniques have.
In this workshop the students will learn how to make a die, how to use the hydraulic press, and how to incorporate this technique saving time, money and achieving an exciting product. They will learn to use their die to the fullest by altering the pressed form before and after it is soldered. Utilizing the same die for different results.

Project Based Workshops

Create a project in a day! Some things that we have created in the past: kiddush cups, vases, salt and pepper shakers, rings, necklaces, specialized techniques such as forging, stone setting, and more. Tell Lisa what you want and she will make it happen!

Jewelry Workshop

Lisa has been teaching specialized jewelry workshops periodically.  Some examples of past workshops are: silver bracelets, wax working, silver fusing, pendants, and more.  To be added onto the e-mail list for workshops contact Lisa
