Pottery/Coloring Underglaze


New to pottery.

I have seen people paint on an underglaze to leatherhard pottery for colour or scraffito purposes.  This seems to me like a usage of an awful lot of underglaze esp for large bowls etc.

I am not making a lot of pieces to warrant making different batches different coloured slips.  

I was wondering in a pinch can I add a bit of coloured underglaze to slip to quickly get a small amount of colour ?  I realise the colour may not be as intense but sometimes just a tinge or subtle colour is all I want.

thanks you in advance

Dear Ama,

    Thank you for your recent question. You could try it as I don't see a problem in the mixture of the two and it should produce some color. Just don't expect to produce significant coloring. For that, you would want to use a stain.

    However, before you try this on a production piece, you will want to test it on a test tile and fire it to see the end results. Making colored slips, glazes and clay is not like mixing acrylics or oil paints. This is due to the chemical transformations that occur in the kiln during firing. Therefore, it is impossible to predict the outcome. Testing is the only way to determine if this mixture will work and since I have not had the need to do this in the past, I can not assure the outcome will be what you expect.

   I hope this helps you. If you have further questions, please feel free to contact me again any time. I am always at your service.
