Intarsia Sgraffito Sponge stamping Inlay This weeks questions come from Ceramics Decorative techniques, by Dolores Ros, c.2005? Barrons Note from Pres: This book is primarily about decoration techniques. There is a 3/5 star review on Amazon, that states it is not useful since all of the recipes, which she lists many are only for Earthenware. Mmm. Does that mean that the techniques are not relevant? Answers: 3. vitrifying engobes -The glaze-firing engobes, also called vitrifying engobes, are applied over dry or bisque clay. Because the application techniques are not the same as the ones for single-firing, their formulas are also different. Some melting material must be added to the formula, so when the piece is baked, the engobe will adhere better and not flake off. 2. Intarsia - This technique in ceramics cannot be compared to its great tradition in other media. In the world of ceramics, examples of great quality can be found in the traditions of other cultures, and in the beginnings of decoration during the seventeenth century, an era in which this technique was prevalent. The basic requirement for using this technique is to have a good pattern. If you cannot find one in specialized stores, make one yourself using tracing paper that is waterproof and can be reused. The easiest technique for working with Intarsia is to use a single cutout design and a pattern. Aside from the difficulty of the project, it’s important to determine whether it requires different colors or several patterns, their placement, and the density of the engobe. The engobe to be applied must be very thick, so much that the brush should be able to stay upright inside the container. Any thinner and it can seep under the edges of the pattern and cause smearing. 3. perforating - As the name indicates, perforation involves decorating a piece by cutting through its walls. Although perforating a piece clearly limits functionality, the intent may be functional, semi-functional, or purely decorative. 4. Inlay- Inlay refers to the process of filling the lines or the grooves of a piece with a similar material but of different color, to produce a smooth surface. Note from pres. . .This is more of a wet clay process as mishima and others are drier.
