Having a perfectly flat base or rim on a pot adds a professional feel to handmade pottery.In this episode, I tell you about an amazingly simple and easy technique to create perfectly flat bases or rims on your pottery. After having read about this pottery technique in a book, it is now something I use on every one of my pots!-------------------------------*New book: Eco-conscious Pottery Colour is available on the Oxford Clay website here.*A paper copy of Eco-conscious Pottery Colour is available from Amazon here.-------------------------------Resources for Potters:Oxford Clay website resources for PottersPottery eBooksDownload the Free How to Make a Pottery Glaze Workbook (suitable for beginners):Download the Free How to programme an Electric Kiln for bisque and stoneware glaze firings (includes full kiln firing schedule)Pottery Paperback Books available from AmazonVideo mini-courses for PottersOxford Clay blog------------------------------------Get your pottery question answered on the podcast!Submit your pottery question to the Oxford Clay podcast by emailing your question to: info@oxfordclay.co.uk with the subject line ‘Podcast Question’. 
Disappointment in pottery can happen when the pot in your mind's eye isn’t the same as the one that comes out of the kiln! That sinking feeling of disappointment can really hold us back as potters and can affect even the most experienced of Potters. In this episode, I talk about three mindset shifts that I use to deal with my own feelings of disappointment in pottery; 1. That disappointment is a natural part of the creative process. 2. That disappointment is a natural part of pottery-making so much out of our control as potters (especially what happens inside a kiln firing!). 3. That experiencing failure and disappointment in pottery means that you are at the growth edge of your skills and experience.I hope this episode inspires you not to be discouraged if feelings of disappointment ever come up in your pottery-making. The book featured in this episode is ‘A Potters Book’ by Bernard Leach, 1976 edition published by Faber and Faber.-------------------------------*New book: Eco-conscious Pottery Colour is available on the Oxford Clay website here.*A paper copy of Eco-conscious Pottery Colour is available from Amazon here.-------------------------------Resources for Potters:Oxford Clay website resources for PottersPottery eBooksDownload the Free How to Make a Pottery Glaze Workbook (suitable for beginners):Download the Free How to programme an Electric Kiln for bisque and stoneware glaze firings (includes full kiln firing schedule)Pottery Paperback Books available from AmazonVideo mini-courses for PottersOxford Clay blog------------------------------------Get your pottery question answered on the podcast!Submit your pottery question to the Oxford Clay podcast by emailing your question to: info@oxfordclay.co.uk with the subject line ‘Podcast Question’. 
It's Autumn here in the UK and the leaves on the trees are starting to fall! But did you know that you can actually make a pottery glaze from fallen leaves?! Whilst wood ash is often quoted in glaze recipes, leaf ash can actually be used instead. In fact it is often the leaves of plants which have fallen naturally at the end of their growing cycle which create the most beautiful pottery glazes!  In part two of this two-part episode series on making pottery glazes with fallen leaf ash we discuss: *How to make a stoneware glaze using quartz, cornish stone, leaf ash and water. *How to weigh out glaze-making ingredients. *How to mix a glaze and sieve it.The eBook Leaf Ash Glazing: A guide to sustainable pottery glazing with fallen leaves is available here.The ash glazing recipe in this episode and also used in the book Leaf Ash Glazing: A guide to sustainable pottery glazing with fallen leaves is:*Quartz - 20 Parts *Cornish Stone - 40 Parts *Leaf Ash - 40 Parts *Water - to make up to the consistency of single cream. -------------------------------*New book: Eco-conscious Pottery Colour is available on the Oxford Clay website here.*A paper copy of Eco-conscious Pottery Colour is available from Amazon here.-------------------------------Resources for Potters:Oxford Clay website resources for PottersPottery eBooksDownload the Free How to Make a Pottery Glaze Workbook (suitable for beginners):Download the Free How to programme an Electric Kiln for bisque and stoneware glaze firings (includes full kiln firing schedule)Pottery Paperback Books available from AmazonVideo mini-courses for PottersOxford Clay blog------------------------------------Get your pottery question answered on the podcast!Submit your pottery question to the Oxford Clay podcast by emailing your question to: info@oxfordclay.co.uk with the subject line ‘Podcast Question’.

Clay shrinks at every stage of the pottery-making process. This can make creating the right size of pot quite tricky!Another confusing thing is that different clays shrink by differing amounts up to around 25 per cent, from wet clay to finished pot. Join me for this episode, where I talk about a simple way to find out how much your specific type of clay will shrink by. I talk you through how I discovered that my clay at Oxford Clay shrinks by 15 per cent from leather-hard clay to final glaze-fired pottery. -------------------------------*New book: Eco-conscious Pottery Colour is available on the Oxford Clay website here.*A paper copy of Eco-conscious Pottery Colour is available from Amazon here.-------------------------------Resources for Potters:Oxford Clay website resources for PottersPottery eBooksDownload the Free How to Make a Pottery Glaze Workbook (suitable for beginners):Download the Free How to programme an Electric Kiln for bisque and stoneware glaze firings (includes full kiln firing schedule)Pottery Paperback Books available from AmazonVideo mini-courses for PottersOxford Clay blog------------------------------------Get your pottery question answered on the podcast!Submit your pottery question to the Oxford Clay podcast by emailing your question to: info@oxfordclay.co.uk with the subject line ‘Podcast Question’. 
Because the process of making pottery is so prone to technical ‘failures’ it can often feel like you're constantly doing pottery ‘wrong’! In this episode, we explore how giving yourself permission to get things ‘wrong’ in pottery as you learn and grow in your pottery-making skills and experience, opens up infinite creative opportunities for your work. I share some things I’ve changed in my own pottery recently and some tips for how to give yourself permission to grow in your pottery-making. Knowing that pottery isn't meant to be ‘perfect’ and choosing thoughts such as ‘I'm doing it right’ (even though it often doesn't feel that way!), really supports our pottery-making learning journey. -------------------------------*New book: Eco-conscious Pottery Colour is available on the Oxford Clay website here.*A paper copy of Eco-conscious Pottery Colour is available from Amazon here.-------------------------------Resources for Potters:Oxford Clay website resources for PottersPottery eBooksDownload the Free How to Make a Pottery Glaze Workbook (suitable for beginners):Download the Free How to programme an Electric Kiln for bisque and stoneware glaze firings (includes full kiln firing schedule)Pottery Paperback Books available from AmazonVideo mini-courses for PottersOxford Clay blog------------------------------------Get your pottery question answered on the podcast!Submit your pottery question to the Oxford Clay podcast by emailing your question to: info@oxfordclay.co.uk with the subject line ‘Podcast Question’.

So many pottery projects involve joining clay together and it’s not unusual for clay to crack apart after it's been joined. Join me for this episode where I talk about my 5 simple steps for joining clay together to stop clay from cracking apart! *Join clay that is the same level of dryness, you can encourage this by keeping clay in a damp box. *Use vinegar to ‘melt’ the joining surface of the clay. *Score the surface of the areas to be joined. *Use slip on the joint (and superpower this by mixing in paper fibres!). *Dry your pottery slowly to prevent some parts from drying faster than others and cracking apart. ----------------------------------Get your pottery question answered on the podcast!Submit your pottery question to the Oxford Clay podcast by emailing your question to: info@oxfordclay.co.ukwith the subject line ‘Podcast Question’. --------------------------------------------------Resources for Potters:Oxford Clay website resources for PottersPottery eBooksDownload the Free How to Make a Pottery Glaze Workbook (suitable for beginners):Download the Free How to programme an Electric Kiln for bisque and stoneware glaze firings (includes full kiln firing schedule)Pottery Paperback Books available from AmazonVideo mini-courses for PottersOxford Clay blog

You may have heard the word ‘Verdigris’ used to describe a blue-green colour, or you may have seen it on brass statues or the roofs of buildings. Verdigris is also a pigment that has been used by artisans for thousands of years. But did you know that Potters can actually make their own Verdigris to use in their ceramics?! Making your own verdigris is a great way to avoid using commercial metal oxides, one of the least environmentally friendly pottery ingredients. In this episode, I tell you about how I make my own verdigris and how I use it in the pottery at Oxford Clay as a unique eco-conscious pottery colourant. Learn how to make your own Verdigris and use it in your pottery in this video mini-course.  Resources for Potters:Oxford Clay website resources for Potters: https://www.oxfordclay.co.uk/resources-for-pottersPottery eBooks: https://www.oxfordclay.co.uk/shop/ebooksDownload the Free How to Make a Pottery Glaze Workbook (suitable for beginners): https://www.oxfordclay.co.uk/how-to-make-a-pottery-glaze-workbookDownload the Free How to programme an Electric Kiln for bisque and stoneware glaze firings (includes full kiln firing schedule) https://www.oxfordclay.co.uk/how-to-fire-bisque-and-stoneware-kiln-firing-schedulePottery Paperback Books available from amazon:https://www.amazon.co.uk/Katherine-Tomlinson/e/B0B1CKC9X3?ref=sr_ntt_srch_lnk_1&qid=1662270837&sr=8-1Video mini-courses for Potters: https://www.oxfordclay.co.uk/shop/coursesOxford Clay blog: https://www.oxfordclay.co.uk/blog-1
Leather hard clay is when the clay has dried a little but is still wet enough to work with. Clay is very versatile at the leather-hard stage, stronger, and less prone to breakage like bone dry pottery (also known as ‘greenware’). In this episode, I explain what leather-hard clay is and all the amazing things that can be created with leather-hard clay! From building slab pots, etching decoration and slip trailing, to turning the base of wheel-thrown pots and more!Resources for Potters:Oxford Clay website resources for Potters: https://www.oxfordclay.co.uk/resources-for-pottersPottery eBooks: https://www.oxfordclay.co.uk/shop/ebooksDownload the Free How to Make a Pottery Glaze Workbook (suitable for beginners): https://www.oxfordclay.co.uk/how-to-make-a-pottery-glaze-workbookDownload the Free How to programme an Electric Kiln for bisque and stoneware glaze firings (includes full kiln firing schedule) https://www.oxfordclay.co.uk/how-to-fire-bisque-and-stoneware-kiln-firing-schedulePottery Paperback Books available from amazon:https://www.amazon.co.uk/Katherine-Tomlinson/e/B0B1CKC9X3?ref=sr_ntt_srch_lnk_1&qid=1662270837&sr=8-1Video mini-courses for Potters: https://www.oxfordclay.co.uk/shop/coursesOxford Clay blog: https://www.oxfordclay.co.uk/blog-1
