Making Tampoes: Felt, Foam and Silk-floss Cores Compared
拓包自制选材对比：毡芯、海绵与丝棉

拓包（扑子）是捶拓的核心工具，芯材决定墨量手感。实测三种：①细毡芯——含墨稳、排墨匀，适合乌金拓大面扑墨，成本约 5 元/个；②高密度海绵——吃墨快但易过量，初学者易洇，适合练习版；③丝绸包裹脱脂棉——墨色最细腻，可作蝉翼拓淡墨，包布用 40 支真丝或涤纶绸。制法：芯径 4–6 cm，包布收口扎紧留 3 cm 短柄，新包先蘸墨在废纸上"养"至出墨均匀再上版。结论：正式创作以毡芯为主，海绵包专做打底铺墨。
The tampo's core decides the ink feel. Three tested: fine felt—steady load and even release, the choice for dense wujin work, about ¥5 each; high-density foam—drinks ink fast but floods easily, best on practice plates; silk over cotton floss—the finest tone for pale cicada-wing rubbing, bound in 40-count silk or polyester taffeta. Make them 4–6 cm across with a 3 cm tied handle, and "break in" a new tampo on waste paper until it feeds evenly. Verdict: felt for finished work, foam for laying ground tone.
