Hey there, fellow clay enthusiasts! Today, we’re diving deep into the world of black slip for cone 10 firing. Finding the perfect black slip can be a game-changer for your high-fire ceramics, much like finding the perfect kitchen knife set is for a chef. Black slip is essentially a liquid clay mixture with added colorants that give it that deep, rich black we all love. When fired to cone 10 temperatures (around 2350°F or 1290°C), it can transform into something truly spectacular.
Why Use Black Slip in Cone 10 Firing?
Black slip is incredibly versatile in high-fire ceramics. Here’s why it’s so popular:
- Versatility: You can brush it, dip it, trail it, or use it for slip casting.
- Contrast: It creates stunning contrasts, especially in sgraffito techniques.
- Texture: At cone 10, black slip can develop interesting textures, from smooth and glossy to rough and matte.
- Depth: High-fire conditions allow the slip to mature fully, resulting in a depth of color that’s hard to achieve with lower fire methods.
- Glaze Interactions: Black slip can create fascinating effects when interacting with other glazes at high temperatures.
Using black slip in your ceramic work can be as transformative as adding perennial flowers to your garden – it adds depth, interest, and lasting beauty.

When firing black slip at cone 10:
- Ensure the slip is completely dry before firing.

- Handle slipped pieces carefully to avoid scratches or chips.

- Glaze fire: Ramp up to cone 10 (about 2350°F or 1290°C) over 8-10 hours, then hold for 15-20 minutes before cooling
Remember, every kiln is different, so you might need to adjust these times and temperatures.
