Pottery Maintenance

Helping a friend get ready for a wood firing in March. She produces salt glazed work. Maybe I`ll get a few pieces in this time….but she is making a living from it so space is at a premium!

Main chamber of kiln. Internal bricks were at one time the same colour as the honey heavies you can see.

Bag wall gets a lot of stick from the firing chamber it backs onto.

Fleen cleaning up one of the carborundum shelves

Smaller front chamber contains fire bars and said fire, plus stuff you want to put in a very hot area!

Salt and silicates plus iron in the clay react to form glossy brown glaze type finish to pieces….can be green/black/purple and pink depending where they are. Very corrosive atmosphere inside this kiln….HCl vapour produced which attacks everything.

Carborundum shelves, these are lovely and lightweight compared to shelves I`m used to. Each one has to be cleaned using, chisels, hammers, grinders and big sanding stones. Quite a job, any glaze left on shelves will melt in next firing and stick your new lot together if it can. Each shelf costs about £100 so hitting it with a chisel can be a nail biting procedure.

Odds and sods off different kilns hanging around. Electric this one…being fixed.

Gas one.

When you add salt through the ports you have to stoke the wood chamber up like the devil, open the baffles on the chimmney, (orange bricks) and the whoosh through draft of hot air should quickly shoot the salt evenly through the main chamber….u hope.

rejects. Here endeth the lesson!

      Oh this is so interesting Viv. Thank you for showing me around. You have some serious kit there. I love the salt glaze on the interior walls of the kiln.
      Can I ask what is the name of your crochendy?
