**David Tsabar recalculation using frit 3134 of a popular Chrome/Tin Red glaze with many names: Scott's Red, June Perry Red, McDonald's Red, Ron Roy Red Burgundy, Purple Red, Raspberry....
Frit 3134 gives pink/purple color and local (Argentina ) frit 804 a nice red.
%analysis frit 804: https://glazy.org/materials/826.
"Maybe" Ferro Frit 3110 can be used for the nice red color.
See pictures with frits 3134 and 804 with different amounts of chrome and tin.
Better results over white body, thick, cone 6 tip touching the shelf. At cone 5 the color is less bright.
**Recálculo hecho por David Tsabar usando frita 3134 de Ferro (174 de Crecer-Argentina) de un esmalte rojo de cromo/estaño muy popular con muchos nombres: Scott's Red, June Perry Red, McDonald's Red, Ron Roy Red Burgundy, Purple Red, Raspberry....
Hice pruebas con Caolín Patagónico y Tinkar Z en vez del caolín. La muestra con Caolín Patagónico parece ofrecer una mejor calidad de esmalte.
También usando la frita 804 de Crecer (Argentina), que parece brindar el mejor rojo. Ver los diferentes resultados con las dos fritas y diferentes cantidades de cromo/estaño.
Mejor resultado sobre pasta blanca, capa más bien gruesa de esmalte y a cono 6. A cono 5 el color es más apagado.
