Hello
I have some clay pots that I have brought back from Africa, they are clay that has been fired in a kiln but not glazed. The clay after firing is a terrcotta colour.
I need to protect them from the UK elements, rain and frost, no room indoors!
Someone suggested painting them with PVA glue which I have done, when sunny they have a shine however everytime it rains they turn white!!
Any ideas
Many thanks

If you can find someone to fire them up to about 300oC or so you should burn out the PVA. Personally I would seal them with Polyurethane varnish diluted with white spirit, that way you don't loose the original appearance of the piece.

i don't know ho wit works on YOUR pots, but i found out recently that a
50-50 mix of future floor wax and water applied to raku pots keeps the raku glazes looking good~future floor wax is an acrylic based material.

Exactly what I was going to suggest. The PVA was not such a good idea, to get rid of it you will have to fire it out. The polyurethane.
I've done this with some of my crackle-glaze raku with good results, but with any of my matt glazes this seriously kills the color.
wow! that mix SAVED one of my real earthy looking matt glazed pots...
it's a glaze called "alligator". blackish with reds & blues here & there. i don't know the details.
oh well
