Episode 27: How Potters Can Make Their Own Colouring Oxides
Commercial metal oxides used by Potters to colour their work are some of the most environmentally harmful pottery materials. However, Potters can circumvent these supply chains by making their own metal oxides from recycled metal! In this episode we explore the process of making Iron Oxide (rust) and Copper Oxide (verdigris) from scrap metal and how Potters can use these homemade colourants in their work.

Thank you so much. I so enjoyed listening to you and love what you’re doing. Bless you 🤗
Thank you for sharing this information! I've not found it anywhere else on the 'net, and have been searching for it for quite a while.
Show the process please
Would have been better with a visual of making colors
Enjoyed you and your video. For me visuals are important and helpful and including them might capture more interest. Thank you.
Thanks a lot! I new in to ceramics and started to make my ow oxides as I live in the middle of the amazon jungle so it's really expensive and difficult to buy it here!! I make brass oxide with swimming pool clarifier I just put the brass inside with water and the clarifier for couple minutes and next day is completely green. then just scrape off. thanks a lot for all the tips!
Love this, thanks for sharing your methods, going to give them a try
Really interesting video, thank you! Would have loved to have seen some examples held up to camera. You're doing great work for the world in trying to make pottery more green. :)
When using scrap copper avoid getting solder into your batch, some solders contain lead.
You are talking about how this is more environmental friendly because you use recykled metal, but then you say you get the coppar from the charity shop and pay more than they would get from recykling. So the gain for the environment isn’t there unless you save the metal from the dump or from being left in nature.
peace be upon you and zamzam water
I would point out that in small amounts iron oxide and copper oxide won't do you much damage. The human body already uses iron and a little copper so the body has some defences against these substances.
Clay dust in the air is really bad for your lungs as the body has no way to disassemble an alumino-sillicate particle so silicosis is a permanent condition.
Please tell me hindi sister
Great information. Are the finished pieces food safe?
If an oxide is mixed with a food safe glaze then it most likely food safe. (Testing is always best).
can copper sulphate also be used for colouring pottery?
Yes, mix it carefully with baking soda, taking care because it will fizz all over the carpet. This makes copper carbonate powder which sinks to the bottom after a while.
Thank you for that really interesting and helpful content!
This has given me soo many great ideas!! I have a few things that my dad gave me when I first bought my home 23 years ago and they are rusty!! I can believe I can take that rust off and use it on something in remembrance from my dad.
Simple and indeed a logical step toward a better environment. Thank you for reminding me of the things we learned at school.
Really interesting so pleased I’ve found you before I start on learning about pottery
love this!! have been wondering the same thing!
شكرآ
I'm excited 🎉
