The first four ingredients and the triethanolamine are melted together, heated to 350'F with stirring, and then the ethyl cellulose is stirred in until the mixture is smooth. Add the iron oxide with stirring. Calcium sulfate makes a cleaner-melting compound which is easier to handle than does iron oxide. |
