There is no standard in the trade for true or genuine, that is, unadulterated golden ocher or chrome ocher, and every color grinder has his own standard or else matches his competitor's brand. As an example of a formula for a pale or light shade of golden ocher, we would suggest 65 parts of J. L. C. E. S. French ocher, i. e., the pale citron shade; 7 parts by weight of a clear shade of medium chrome yellow, and 28 parts by weight of clarified or refined linseed oil, for 100 parts of paste. Lemon yellow should not be used, as it would make the color too flat-looking, too sad, as some would term it. For a dark or deep shade of golden ocher, would suggest 65 parts by weight of J. F. L. E. S. French ocher (dark shade) and 7 pounds of a light shade of orange chrome yellow with 28 pounds raw linseed oil, grinding the mixings in either case on same kind of mills as French ocher. For convenience and prevention of waste, when small batches only are to be produced, we suggest the following formulas: - For light golden ocher in oil, mix in a suitable mixing can and beat up until smooth and free of streaks, 90 parts by weight of French yellow ocher in oil and 10 parts by weight of medium chrome yellow in oil. For the dark golden ocher follow same proportions, but use J. F. L. S. ocher in oil and orange chrome yellow in oil, that must be perfectly free from paint skins in either case. Chrome ocher, when expected strictly pure in oil, is only another name for golden ocher, and our formula for light shade will answer here, because it should be made only by the addition of neutral lead chromate, not the basic chromate of lead to ocher. When bought in quantity chrome ochers are not expected to be pure ocher and chrome yellow, but a sort of golden ocher with a marigold tint. The usual selling price for this material is not above, but rather below, that of the pure French yellow ocher in oil, and the goods sold under the brand chrome ocher are really imitations of golden ocher. At least, the various analyses had of specimen samples would show this. The best of the samples analyzed could be matched very close in color, tone, strength, etc., by mixing 17 parts J. L. C. E. S. ocher, 3 parts medium chrome yellow, 1 part Venetian red, 12 parts whiting, 50 parts floated barytes, and 17 parts raw linseed oil, for each 100 parts of medium soft paste. This analysis came fairly close to the result from the analysis of an imitation of golden ocher sold in dry powder at a fairly low figure. On the strength of the foregoing it will not be difficult for any grinder of experience to formulate mixings and grindings of yellow ocher for the consumer's requirements, and so long as he does not practice deception by using deceiving terms no one can take exception to the class of goods he makes for his patrons.
