There have been few masters of the art of plique a jour, most notably,             

Fernand Thesmar, Gustave Gaudernack, Rene Lalique, and P. Ovchinnikov throughout history.

But in the last 75 year the US gave home to an exceptional plique a jour artist  Mr. Timofeev, whom existed in the grand tradition of the dynamic enamelist whose convictions and workmanship demand respect.

He is completely independent from any influence of plique a jour that would suggest a side track, a reliance upon tentative worth or speculation.
