Giovanni Corvaja gives private tuitions in his studio in the centre of Todi, a small historical town in central Italy, near Perugia.

These are intensive courses of five days for four people at a time. The workshop is fully equipped and spacious enough to fit four people at work comfortably. This number of students is optimal, as it is creatively stimulating and cost effective for the participants.

The course is aimed at people with basic jewellery-making skills, at least.

The course is held in English or Italian.

Each student will obtain a certificate of attendance at the end of the course.

This course focuses on learning how to choose, make and use the most appropriate alloy for a particular design. The choice has to be made according to the aesthetic and mechanical proprieties that one is looking for.


During the course students will understand on a deeper level the metallurgical proprieties of precious metal alloys, and learn to calculate, melt and work alloys correctly.

The focal points of the course are the following:

  1. Choosing the right alloy for a particular design

  2. Calculating the alloy

  3. Preparing the components for a certain alloy

  4. Melting the components to make the alloy

  5. Working with as many alloys of gold, and optionally platinum,

  6. as possible

All necessary information will be given for various alloys, during the course:

  1. Melting temperature

  2. Hardness

  3. Annealing temperature

  4. Hardening temperature

  5. Heat diagram

  6. Specific gravity

  7. Possible applications

Each participant is asked to bring the following materials and equipment:

  1. Some square crucibles in ceramic (4x4 cm)

  2. Protective goggles

  3. Pure gold to make as many alloys as possible

  4. Pure silver (30 grams)

  5. Pure platinum, for those who are interested in experimenting

  6. with this metal

  7. Tweezers

  8. A set of basic hand tools
