The Art College where I took my degree course had three main departments; Painting and Sculpture (mine), Weaving, and Pottery. The Pottery department had an excellent national reputation.
In the years when I was a student, there was a fashion amongst the potters for building experimental outdoor kilns, and for firing Raku pots.
Raku (as I understand it) is a risky Japanese method of firing and glazing all in one go, by heating-up the kiln to very high temperatures, firing for a very short while, then removing the pot whilst still 'red hot'. Many pots don't survive this extreme treatment, but those that do are often crackled, pitted, and very beautiful.
One of the advantages of hanging around the college's Pottery dep't (apart from the fact that it was awash with beautiful girls), was the possibility of being given their casts-off.
These two Raku pots, above, are a good example of their rejects. OK, they're not the world's finest, but they are practical, attractive, and were free. The fact that I still have them, and that they are still in constant use, means that for me (at least) it was right to save them from the wrecker's hammer.
I wish I could remember who made them!
