Going BIG - How To Combine Thrown And Slab Pieces

Have you ever wanted to make a tall or really wide piece, but your clay gets too flimsy and the piece falls apart? Well, in today's post, I'm going to show you how to add slabs to a thrown base and top to make a tall jug.

Whoever invented this method was a genius! I've had several requests over the last few years for large jugs however; I don't throw large pieces often so I find it a bit challenging. I discovered this method a while back, and have used it a couple times.

Are you ready to be amazed at how simple a 16" jug can be? Well, grab your coffee and apron and let's get to the studio!The first thing you need to do is decide how big you want your piece. Once you've determined size, think about how it would join together best and get throwing.

I've decided I want my jug to be 16" tall and about 10" wide. From past experience, I know that I can throw a bottom, a collar and a neck, then make a slab to make up the difference.  For instance, the bottom on this jug is 4" tall, the collar piece is 4", and the neck is 4", leaving a 4" difference to be filled in with a slab.

Here are the steps:

  • Using roughly 1.5 lbs. of a nice throwing clay, make a base for your jug.


  • Using slightly less clay, throw a collar. Make sure you use calipers to measure the base piece and throw the collar the same size.


  • Now, throw a neck. Again using the calipers to make sure the neck piece will fit the collar piece.


  • Roll out a slab of clay long enough to roll into a ring that will fit on top of the base
    • Note: this is the perfect time to add a design to the slab piece


  • Allow all the pieces to get "leather hard", then score, slip and join the pieces
  • Add a handle
  • Loosely wrap the jug in plastic for a couple days so it dries evenly
  • Bisque fire
  • Stain, glaze... finish however you want

So, how's that for going big? Give it a try... By the way, you don't have to make a jug, you can make a large bowl, vase, crock... use your imagination!

    I can't for the life of me figure why you would show pictures of all the separate pieces and not show us a pic of the finished project so we can see what you were going for. It's an interesting concept, but I am always disappointed in a blog, video, etc that does not show finished product. You wonder if it didn't work out well in actual practice.
