我非常喜欢使用 AMACO 底釉与水彩底釉，因为其效果更具绘画感，也更易于掌控。AMACO 底釉本质上就是着色黏土，仅由黏土、少量水和颜料组成。你可在陶土入窑烧制前就施用底釉，也可将其涂于素烧坯（bisqueware）之上——后者是我更偏爱的方式。

我最钟爱的技法是：将黑色、棕色或红色（任选一种能凸显刻痕区域的颜色）底釉加水稀释后涂抹于作品表面，再用海绵擦去多余部分。这种处理可营造出做旧效果，使陶土作品比单一光泽釉层更富表现力与动态感。我尤其喜欢在人物造型或浮雕肖像创作中运用此法。你可以自由控制留色多少，这种类似染色的技法还能强化所有已塑造出的表面肌理。
丝绒底釉非常有趣，因其允许你自主选择哪些区域呈现亮光效果、哪些区域保留丝绒般的哑光质感。只需叠加涂刷透明亮光釉，即可形成高光区域。务必确保底釉颜色已完全干透，以免后续施加亮光釉时发生晕染。该亮光釉初呈粉红色，可能令学生困惑，但经锥度 05（Cone 05）烧成后，将呈现通透亮泽的效果。请均匀涂刷三遍，并确保每遍之间彻底干燥。

我超爱这些水彩底釉，因为它们极易掌控——你总能预知最终效果，且所呈现的色彩恰到好处，足以温暖整件作品。尽管价格略高，但用量极少、功效显著，每套产品均提供丰富多样的色系选择。我通常将这类底釉专用于《雕塑 II》及 AP 3D 课程的学生。

I love to use amaco underglazes and watercolor underglazes because the results are more painterly and easier to control. Amaco underglazes are simply colored clay, so it is just clay, a little water and pigment. You can use underglazes on clay before it ever goes in the kiln or it can be applied on bisqueware, which is what I prefer.
This detailed tutorial is ready for the classroom:

My favorite technique is to use watered down black, brown, red (whatever color that will make your carved areas pop!) and wipe off with a sponge. This gives an aged look that makes clay look more dynamic than one solid coat of a gloss glaze. I love using this technique in figurative work or with sculpted portraits. You can add as much or as little as you like and the stain like technique enhances all the surface textures you created.
Velvet underglazes are so fun to work with because you can choose which areas are glossy and which areas retain the velvet/matt. Add layers of the transparent gloss glaze to create high shine areas. Make sure your underglaze colors are 100% dry first so they don’t smear when you add the gloss coats. It comes out pink, which may confuse students, but will fire at Cone 05 for a glossy and translucent finish. Apply three even coats and let it dry completely between each coat.

I LOVE these watercolor underglazes because they are so easy to control. You know exactly what they will look like and they create just enough color to warm up a piece. Although they are a little expensive, a little goes a long way and you get a large variety of color with each set. I usually reserve these for my Sculpture II and AP 3D students.
