Where does your clay come from?
There is clay in many places throughout Auckland and the rest of New Zealand.Dig down under the topsoil you might find some at your place.The clay from Half Pint pottery in Hunua Gorge needs a lot of processing and additives to make it suitable for making pots.(We did make a pizza oven from it )We find it easier to buy clay from local suppliers.All of the clays are tested to make sure they are suitable and that they fit our glazes.
How mUch Does clay Cost?
Clay is often not included in our class prices because of the variation in prices.Red terrocotta clays tend to be cheaper starting at $25 per 10kg bag to white clays which can be up to $45 per 10kg bag.
One bag of clay is usually enough for a six week two hour class.
