What Is Slip Trailing | Glazing Tips Tools and Ideas

Pottery is a form of art that allows exceptional flexibility in expressing one’s self. The possibilities in crafting are endless and slip trailing can amplify it even further.

So, what is Slip trailing? Slip trailing is a technique in pottery where a Potter applies Slip (watered down clay with or without colorant onto mainly leather hard clay) using a Bottle, Bulb or Flexible Container that has a pointed tip. Slip trailing adds another dimension to pieces through decorative lines or unconventional shapes.

It’s a highly flexible decorative technique that uses a Slip Trailer or other Applicators. These tools can be in the form of commercial applicators, bottles, cake decorators, or squeeze bottles.

When Bisque fired, Slip trails create raised textures or contrast to the surface. With enough creativity, a Potter can add more depth to Ceramics. Although it will take a lot of practice to perfect Slip trailing, the process of learning will be fun, and you can apply it to your pieces almost immediately.

Basics of Slip Trailing

Slip trailing is different from applying glaze to your Craft. Unlike glazing that adds the finishing touches and shine to your art, potters use Slip trailing to Pottery that is Bone dry, Leather hard, or even Workable Stage to create textures and designs. Technically you can apply Slip trailing to bisque ware but it can be tricky because of the different shrinkage rates with the Slip and Bisque piece.

The raised surface that you create when you apply Slip provides a physical and visual texture that adds depth to your pieces. It stays in place, doesn’t move, run or flatten, so what you see before bisque firing is what you get for your finished product.

If you use Colored Slip, it’ll stay in place, and it becomes a part of the pot.

It’s best to have exceptional precision when Slip trailing. Careful planning and execution will save you from several trial and errors.

However, you can remove slip trailing from your bisque piece by simply sanding it off (always wear a dust mask when sanding).

If you didn’t bisque your slip trail on to your bisque ware you can wipe off your slip trailing with a sponge. Removing the slip trail from greenware is more difficult.

It can be a little challenging when you use slip trailing for the first time, and it’ll take some time and effort before you can craft beautiful trailed pieces.

Potters who are working with slip trailing for the first time can follow these simple steps to get started:

  • Develop a design idea that you want to use for your craft. It can be an abstract design or bits and pieces of elements that create a consistent look throughout your ceramic.
  • Select the tools that you’ll use for your craft. It needs to fit the characteristics of the design that you want to create. If you’re going to apply fine lines throughout your piece, then you need an extra-fine tip for your applicator.
  • Familiarize yourself with how each applicator works, then practice working on a slab. Remember, what you see is what you get when slip trailing, so you should keep practicing until you’re satisfied with the design that you have on the slab.

Keep improving your slip trailing skill until you get the design that you want. Only then should you start working on an actual piece.

How to Make Your Slip

Slip is the most vital ingredient in slip trailing, but you don’t have to spend money on it. Buying it is perfect when starting to learn the basics of slip trailing because it shows you the consistency and softness that you need for this technique.

Once you understand how the process works, it would be best if you use scraps of clay from the pieces that you created. Using the same clay allows you to maintain the consistency of your craft and its design. Here’s how you can make the best slip for trailing:

  1. Soak scraps of clay in water. You can have as much as you want because you’ll store the excess for future use anyway.
  2. Keep stirring the mixture until it becomes slurry. It needs to be soft enough to use for designing your craft, but not watery that you can’t form a shape using it.
  3. Use an extra-fine screen to remove all lumps and grog. We recommend at least 80 mesh, but you can use a finer sieve. The texture of your slip should be consistent and smooth, especially when working on intricate details for your pieces.
  4. Store it in an airtight plastic container to keep it suitable for future use. If you’re going to use different types of clay for your pieces, it would be best to have different slip containers to maintain the consistency of your ceramics.

 Having a premade bucket of Slip is the most convenient way to go, so you don’t have to spend time making a new batch every time you want to Slip trail.
