Mastering Oil Varnish

Masterclass on the preparation and application of oil varnish for luthiers

 

Programm for 2019:

The masterclass reveals a great part of my own experience, based on practice and experimention, fulfil with lectures and sharing with collegues and chemists.

A theorical part will help trainees to understand the mechanism of chemical reactions in order to anticipate the different steps of varnishing.

We will focus on varnish preparation, cooking and application.

The trainees will receive matured varnishes in order to start varnishing from the first day.

These varnishes are prepared on the same basis of those we will be making.

Coming with an already stained instrument (or with a ground) is recommanded. A protocole can be sent by e-mail if needed.

At the end of the week, each trainee will carry home a bottle of each varnish made during the course.
