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 plisieurs 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 plurajn glazurbazojn kun sukseso.
