I want to cover a vase with combination of different clay slips (terracotta , black clay, porcelain , RIO clay slip , and cupper oxide clay slip ) on different spaces over the clay body - cone 6 ox I want a shiny met look like the one of terra sigillata what do you think I should add into the slips ? and in what proportions ? silica ? fieldfare or maybe a frit ? thanks

I have a deep and enduring fascination (infatuation?) with Japanese ceramic surfaces, but modern matte ones get me weak in the knees. I have been crushing all over Hashimoto´s black crackle slip/engobe, metallic cracks, and overall textured slip surfaces (check out those interiors) for about a year. Hive mind, how does he do it? Composition ideas? Kohiki "light" with manganese? Double firing? I´d love to experiment with similar textures... but don´t find much info out there on formulating this texture. Cheers and love from Chile! xo - Heather

Hi folks, time for another topic, and don't forget you may post new ideas for QotW in the pool here: Of late I have considered some changes in the decorative process, I have often been interested in surface decoration and texture. I have probably done the gambit of Impressing, incising, piercing, added on clay or sprigging. In my earlier years I did mostly glaze dipping over bare surfaces, then spraying glazes through lace, and silk flower/leaves, along with calligraphic brushwork to bring out or add details. The last 20 years have been more about texture in the piece; first was faceting, then incising the unshaped cylinder. Then I started stamping, and forcing more into the clay to the point I often had to repair the piece when leather hard. Glazing was completed by spraying from different angles to highlight the surfaces. Lately I have considered returning to the smooth surfaces for large areas, with other areas of texture applied before the shaping. I would then decorate the smooth areas as mentioned before with stencils and inglaze work. QotW: What is your predominant method of decorating the greenware, and how do you deal with this decoration in your glazing? best, Pres
