Here are the results of a theoritical study using
Richard Zakin’s programme, Describ9.
This programme allows to obtain a statement of
the aspect of a glaze base already in use or of
one you want to develop. I have used this
programme since 1995 to develop many
glaze bases with success.

Voici les résultats d’une étude théorique
réalisée utilisant le programme developpé
par Richard Zakin, Describ9. Ce programme
vous permet d’obtenir un jugement sur
l’aspect d’une glaçure déjà en service ou
d’une que vous voulez développer. J’ai utilisé
ce programme depuis 1995 pour développer
plusieurs bases de glaçures avec
succès.

Jen faraĵoj de abstrakta esploro efektivigita
usante la programo kreita per Richard Zakin,
Describ9. Tio programo vin ebligas akiri
juĝon pri glazuraspekto jam en servado aŭ
kion vi volas kreskigi. Mi usis tion programon
ekde 1995 por kreskigi pluraj glazurbazojn
kun sukseso.
