Step 1: Prepare Your Clay
Roll out your clay slab to desired thickness (typically 1/4" to 3/8" for plates and bowls) on a non-stick surface or canvas. Let clay rest until leather-hard for cleanest cuts, though soft clay also works.

Step 2: Position the Cutter
Place the cutter firmly on your clay slab with even pressure. For best results, ensure the entire cutting edge makes contact with the clay surface.

Step 3: Cut Your Shape
Press down firmly and evenly around the entire cutter edge. For thicker slabs, use a gentle rocking motion while maintaining downward pressure. You should feel the cutter reach through to your work surface.

Step 4: Remove Excess Clay
Lift the cutter straight up. Peel away excess clay from around your cut piece. Save scraps for recycling back into your clay body.

Step 5: Refine and Shape
Smooth cut edges with a damp sponge. For bowls and dishes, transfer your flat cut piece to a mold, drape form, or use hand-forming techniques to create dimension while the clay is still pliable.

Pro Tips:

Dust cutter edges with cornstarch for ultra-clean release
Clean cutters with a damp cloth after use to prevent clay buildup
Allow cut pieces to firm up slightly before moving to prevent warping

Sizing

Latte Mug – 3" base, 4" rim, 4.8" tall
Standard Mug – 2.5" base, 3.5" rim, 4" tall
Martini – 1.5" base, 4" rim, 3.6" tall

Each clay cutter is sized to create a wall that sits on top of a base. Use the Cups + Cones clay cutter to cut your wall shape, then cut a circle that matches the base size (3", 2.5", or 1.5"). Bevel the joining edges of the wall, then wrap and join the wall into a cylinder on top of the base. For the Martini Clay Cutter, use a 1.5" base if you’re attaching it to a stem, or size up the base for a stable, stemless martini cup.
