    To completely protect from frost you need stoneware clay and glazes which will need to be fired up to 1220deg +

      You can buy heavily grogged clays which are good for outdoor use, and even frost-proof clays. When you buy them from the supplier there will usually be information on firing temperatures etc. Ivanhoe is a good groggy buff clay (I think it glaze fires to 1260 but don't quote me on that). Frostproof terracottas are available, although I've never used them myself, but most terracotta would usually glaze fire to about 1180. Check with your supplier.

        thanks for that. I was hoping it would be earthenware since the glazes are much more colourful. can you not use earthenware glazes with stoneware or does anyone know a good colourful brand of stoneware glazes?
        thanks

          You can get brush on stoneware glazes from BOTZ - and they've got some nice bright colours. www.potclays.co.uk sell them.

            You won't get very good results putting earthenware glazes on stoneware clay as the clay won't vitrify properly and the glaze may craze. As Kate says, there are some nice stoneware glazes available these days - check out www.pottersconnection.co.uk, www.potterycrafts.co.uk and www.potclays.co.uk as they should all have galleries where you can see the colours before you buy.
