Passionated by the manufacture of glass, by minerals and by alchemy, I started to work on my own recipes of colored glasses in 2013. 

I has been very motivated to enlarge our existing borosilicate colors palette by creating new types of colored glasses using the developments I realized these last years concerning the addition of large quantities of minerals or metals with borosilicate glass.

The idea to create a finished product destinated to be used as "first matter" by other glass blowers for creative purposes also attracted me a lot.  On this page you will can discover the five differents types of colored glasses that I developed at this day, some of them are true composite materials and are offering to glass blowers the possibility to add differents types of matierials into their glass creations. 

In the alchemical tradition, the work of glass and the art of imitating natural gems by making colored glasses is one of the possible ways to achieve the "Great Work"

.«The famous formula V.I.T.R.I.O.L. asks the apprentice alchemist to visit the interior of the earth, then work the collected material in order to obtain the "philosopher's stone". This is what the Glassmaker does, he takes his basic materials from the ground: ash from roots, sand, lead and various other metals and minerals, works them by mixing, annealing and he obtains this pure and brilliant precious matter, the glass or crystal which is assimilated to gold.»
