A DIY Underglaze Applicator for Fine-Line Drawing on Clay

When ceramics intersect with skills learned in other disciplines, unexpected tools can emerge. For example, Inbal Hoffman developed a great tool for fine-line decoration based on their years as a tattoo artist.

In this post, an excerpt from the February 2026 issue of Ceramics Monthly, Inbal shares how they adapted familiar tattoo-transfer materials and modified a simple slip-trailing tool to create an underglaze applicator capable of producing smooth, consistent curves. If you like to "ink up" your pots, but have struggled with achieving fine lines and detail, you'll love this practical, low-tech solution. –Jennifer Poellot Harnetty, editor

Preparation 

Begin by modifying the pipette. Cut off the tapered tip with a craft knife, leaving the bulb intact (1). The hole should be slightly smaller than the metal applicator connector so it fits tightly. 

Then, fill the bulb with color (2). Use another shortened pipette to draw underglaze into the bulb almost completely, then attach the applicator tip. Make sure to seal the connection. I recommend wrapping medical tape around the joint between the bulb and applicator (3). The tape’s elasticity ensures a snug, airtight seal. 

1 Use a craft knife to modify the pipette. 2 Use an intact pipette to move underglaze from its original container to the modified pipette.

With the color filled, next, wrap a layer of grip tape over the medical tape for a more comfortable hold during long sessions (4). Finally, attach the needle. The 26-gauge applicator tip is the smallest usable size for underglaze, but larger blunt tips would also work. Twist the blunt applicator tip about half a turn into place—and your applicator pen is ready (5). 

3 Insert the metal applicator connector and use a strip of 3M Transpore Surgical Tape to seal the connection point. 4 Cover the taped connection with grip tape to add security to the seal and comfort of use.

5 Twist on a 26-gauge-applicator tip.6 Inbal Hoffman’s finished work showing the fine lines achievable with this applicator.
