采用刮擦技法的陶瓷盒
为与七年级学生制作此类陶瓷盒，我们首先设计了一个纸质模型，画出构成盒子所需的各个部件的轮廓线。确定尺寸后，我们用胶带将纸质模型组装起来，以检验各尺寸是否协调一致。
尺寸经核实无误后，便以此模型为依据，从陶泥板上裁切出盒子的各个部件。所有需拼接粘合的部件边缘，均用小刀或刮刀切成45°斜角。如此一来，盒子成品将看不到任何接缝痕迹。待全部部件准备就绪，我们通过压纹（knurling）并在所有待粘合部位涂上泥浆（slip），完成组装。同理，盒足、盒盖及盒钮等细节部件也依此法制作。
当各部件干燥至皮革硬度时，便为其施涂一层釉料（engobe）色层，再用刻刀或木制牙签在着色表面刮划，形成“刮擦”（sgraffito）装饰效果。素烧完成后，将素坯通体覆上透明结晶釉，再进行第二次烧成。
Ceramic box with sgraffito
To make these ceramic boxes with the 7th grade students, we first of all designed a paper model, drawing the outlines of each element useful for making up the box. Once the dimensions were decided, we assembled our paper model with adhesive tape, to check the consistency of the measurements.
Once the measurements have been verified, the model is used to cut out the parts of the box from the clay slabs. The edges of the various parts that need to be assembled and glued together are cut at 45° with a small knife or spatula. In this way our box will not have any signs of joint. Once all the pieces have been prepared, they are assembled by knurling and spreading the slip on all the parts to be joined. In the same way we proceed for the details, such as the feet, the lid and the knob.
When the pieces have dried to leather hardness, you proceed by giving a coat of engobe color and scratching the colored surface with a burin or a wooden toothpick to obtain the GRAFFITI decorations. After the first firing, the biscuit is covered with transparent crystalline and the second firing is carried out.
