Waterproofing and Frostproofing Clay Pots

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.
