Designing a Chasing Taster Class and Advanced Assignment Sequence
錾刻体验课与进阶作业序列设计
标签：课程设计, 体验课, 作业序列, 教学
2 小时錾刻体验课大纲：0–20 min 安全须知、胶盘与錾具认知；20–60 min 在 0.8 mm 预退火紫铜上正面走线（固定梅花图样）；60–100 min 翻面顶出两瓣浅浮雕；100–120 min 硫化做旧并装卡留念。进阶序列按"线—面—深—透"四级设计：线纹作业要求线宽偏差 ±0.1 mm；浅面作业控制背景平整度；深浮雕作业限定减薄 ≤25%；透雕作业在 1.0 mm 黄铜上开 3 窗。每级作业随附退火次数与工时记录表，作为升阶依据。
A 2-h chasing taster: 0–20 min safety plus pitch bowl and punch familiarisation; 20–60 min front-side lining a fixed plum-blossom pattern on pre-annealed 0.8 mm copper; 60–100 min flipping to push two shallow lobes; 100–120 min sulphide patina and mounting. The advanced sequence runs line-surface-depth-openwork: line work held to ±0.1 mm width, surface work judged on background flatness, deep relief capped at 25% thinning, openwork cutting three windows in 1.0 mm brass. Every level submits anneal-count and time logs as the basis for progression.
