Have you ever had it, that moment of truth, when you wait so patiently for the kiln to cool, counting down the temperature to be able to crack that lid and take a peek inside? Sheer excitement, just like Christmas morning, you can’t wait to see the pots you spent so many hours, days, and weeks creating.
As you open the lid and look down at the shelf of pots, it becomes obvious that many of your pieces are no longer nice and round, but horribly ovaled at the rim. Devastation hits you. So much effort has gone into those pieces, so many pieces that aren’t top quality products to be able to sell, and why is this happening? The questions come flooding in, the frustrations hit you, and you feel like closing the kiln and walking away, wishing those pots would just fix themselves.
Warping: we all hate it! It's something that doesn't show up until the end of the process, after so much time has already been invested into the piece and it can no longer be...
Before we even talk about making slip casting molds, we need to discuss something important, your prototype. This is what you will make your mold from (some people call it a model)
Why is your prototype so important? It dictates what your cast product will be. If you have marks, rough spots, or unintentional lines on your prototype, it will show up in your cast. If you don’t make your prototype right, it won’t release from the mold.
In my several years of mold making, I have learned along the way some helpful tips to making successful prototypes. So, I’ve decided to share these with you today!
#1. Use a smooth, white clay
Using a white porcelain or very smooth white stoneware clay is better than using a grog red or brown clay. The porcelain clay is easier to get perfectly smooth. If you use a grog clay, those little tiny beads of grit are hard to smooth out and can show in the plaster mold, and in your cast piece.
Using a white clay will make...
You might be interested in slip casting, but unsure how to go about getting your studio ready to start such a task.
If that’s the case, I am going to share with you how I set up my studio for slip casting. It really isn’t as complicated or expensive as you might think, all it takes is a little creativity to transform your space and create your own tools and equipment, which I know you already have!
SPACE for casting: Molds take up more room than sitting down and throwing at the wheel. You will need some table space to set your molds on while they cast. If you don’t have a table, not to fret, you can improvise - floor space works fine, too! Or use a portable folding table. They come in many lengths to fit what works for you and can be removed when not needed.
PAILS for slip: Your slip will likely come in boxes or in a bag inside a pail. Having some good pails on hand will be extremely helpful for you. I prefer a 3.5 gallon sized pail as it...
Slip casting molds are becoming increasingly popular among potters right now. Are you curious to learn what all the hype is about? I’m here to fill you in.
Here’s the thing. There are definitely some myths going around about mold making and slip casting. This is simply due to a lack of knowledge on the topic, and I’m here to debunk these myths and help you understand more about the process.
The slip casting process has been deemed as being removed from the handmade nature of pottery. However, this isn’t the case at all and let me tell you why!
Just like throwing, slip casting is just one step in the whole process of ceramics. You still need to make your molds, know how to handle your slip and slip cast, not to mention all the steps that come after that with trimming, finishing, firing, and glazing.
A slip cast piece gets handled just as many times as a thrown piece does. It still takes time, skill, and knowledge...
I have something super exciting to share with you! I haven’t shared very much on this topic before, but decided it was time to let you in on my own little world and give you a...
TOUR OF MY STUDIO!
This is really special because I have never shared these details before. And I really hope watching a tour of my studio and hearing how I have laid it out will help you with planning your own studio space.
WHAT MAKES MY STUDIO SPECIAL?
My studio is a bit unique, or should I say TINY! And I still have been able to produce thousands upon thousands of pieces in it, attend numerous craft shows, and serve over 50 different retailers in North America with my products.
I’ve mastered cramming a lot of stuff in one small space let me tell you.
I want to walk you through my studio because I think you can relate. You don’t have to have a big fancy studio to start or lots of space, or even running water. And I hope...
Slip casting is a process that uses a form of clay that is liquid. The liquid clay gets poured into a plaster mold. As the time progresses with the slip in the mold, the plaster draws out liquid from the slip. This leaves a clay wall against the inside of the plaster mold. Once sufficient time has passed that the slip has sat in the mold and the clay wall is the desired thickness, the excess slip gets poured out of the mold. The mold is then left to dry until the clay form inside the mold releases from the plaster and shrinks enough to be removed from the mold.
Slip casting molds are becoming increasingly popular among potters. Slip casting allows more difficult and detailed forms to be produced at an easier level. It opens up the opportunity to create non-round forms (like the wheel produces) at a much faster rate than hand building and altering forms. It also makes the construction process simplified allowing for more...
