projet de recherche mené il y a 15 ans par mon ami Bernard Brunette et moi-même.<br /><br />Hardwood ash was used, it was washed 5 times and 200 mesh-sieved.<br />De la cendre de bois dur fut utilisée, lavée 5 fois et tamisée à 200 mailles.<br />We used Ash Berhens for ease of calculating molecular analyses.<br />Nous avons utilisé Ash Berhens pour faciliter le calcul des analyses moléculaires<br /><br />Ash Berhens :<br /><br />Richard Berhens, a famous glaze chemist, proposed a mixture of<br />raw materials to substitute for wood ash.<br />Richard Berhens, un célèbre chimiste céramique, a proposé un<br />mélange de matériaux de base pouvant être un substitut de la<br />cendre de bois.<br />This substitution has the following analysis.<br />Cette substitution a l'analyse
