#111
01/18/2026

Learning how to make pottery on the potters wheel can be quite a frustrating process! I’m still learning all the time, and these mindset shifts have really helped me:

⭐Making pottery is a creative process. You don't have to make pottery ‘perfectly’. There are opportunities to continue to craft your pot at the turning/trimming stage.

What is Rutile in Pottery and What are the Alternatives
#97
08/10/2025

Rutile is a form of Titanium ore with Iron deposits and is used in pottery to create brown, orange and yellow colours in pottery glazes. Rutile is also used to create beautiful speckled effects in glazes.

However,  there are some issues with the global Rutile mining industry, such as high energy consumption and the displacement of people from land, in order to mine Rutile.

If you didn’t want to use Rutile in your pottery, there are alternatives to using Rutile in glazes!  Plant ashes (particularly ash from fallen leaves), for exam...

Being inspired in pottery can happen anywhere, at any time!

In this episode, I talk about 5 surprising sources of inspiration for making pottery that I’ve experienced as a Potter:

Simple Ways to Fix Imperfections in Fired Pottery
#94
06/29/2025

Imperfections are a natural part of pottery, and many of these only manifest after a pot has been either bisque or glaze fired.

But you don’t need to throw a pot away just because of a minor imperfection!

In this episode, I talk about four very common imperfections in fired pottery and simple ways to fix them: 

✔️Hairline cracks appearing in pieces of pottery after the bisque firing, in pieces of pottery that have been joined together

✔️A rough surface after a pot has been glaze-fired...

Can you Colour Clay Using Verdigris?
#92
06/01/2025

Some potters create coloured pottery by mixing oxides and stains into the clay itself before firing. A technique that uses this is called agate, where different coloured clays are combined in layers and mixed, to create a design. 


Recently, I’ve been wondering whether this would work with the home-made pigment verdigris created from recycled copper.

In this episode, I talk about some experiments I’ve done adding verdigris to clay at a ratio of 3% and 5% dry powdered verdigris to wet clay.

13 Amazing Reasons to Make a Pottery Glaze from Fallen Leaves
#89
05/04/2025

It's Spring in the UK, and this is an ideal time to identify deciduous trees that will drop their leaves in the Autumn. Or perhaps you live in the southern hemisphere, where deciduous trees are doing this right now!

Did you know that any plant material can be burned into ash and made into a pottery glaze! Leaves are no exception to this, and many beautiful pottery glazes can be made with leaves that fall naturally as part of a plant’s growing cycle.

Flat rolled out clay has a very annoying tendency to curl up as it dries! 

In this episode I talk about the three things I do in my pottery to make ‘perfectly’ flat (although nothing in pottery is ever perfect!) drinks coasters.

Can You Use a Silicone Mould in Pottery?

Yes you can! In fact they are an amazing way to add beautiful decorative details to pottery.

Silicone sugar craft moulds from cake making can be used by Potters who want to create intricate surface decorations for their pots. Clay is simply pressed into the mould, left to dry a little, removed from the mould and then attached to pottery as a sprig decoration.

I use silicone moulds in my pottery to make dragonfly, butterfly and bird decorations that I then attach onto my pottery with slip.  In this episode, I s...


How Potters Can Use the Circular Economy
#85
03/30/2025

For the last 200 years, industrial society has used a linear economic model that takes raw materials, makes them into products, sells them to consumers who then eventually throw them away. Natural resources are ‘lost’ in this process and this model is widely regarded as unsustainable. 

Contrastingly in the circular economic model, resources are continuously reused, recycled and retained in the supply chain.

In this episode, I talk about some opportunities for Potters to use the circular economy model and reuse materials in their work, such as;

Some thoughts created by our brains, support us when making pottery, and some definitely less so! Join me for this episode where I talk about some thoughts I've had in pottery that haven’t supported my pottery such as ‘I’ll never be good at pottery’, ‘I’ll never be as good as them’ (in an evening class setting) and ‘I don't like my finished pot’!  

I talk about some alternative thoughts you can replace these with to truly support yourself in your pottery-making and make your mind a safer and kinder space to learn.

How to Design Pottery For The Environment
#81
03/02/2025

Designing for the environment is a way of creating products where the minimum possible negative environmental impact on the environment is intrinsic to their design. 

In design for the environment, a product is thought of holistically, from the raw materials used to make it to its manufacturing process. 

Potters have a huge opportunity to design for the environment because we have direct control over how our pottery is made and the ingredients we make it with. 

In this episode, I explain the three different aspects I used to...
