I am so excited! My friend and colleague Katrine taught me how to raku-fire pottery today. It\u00b4s something I\u00b4ve been wanting to learn for ages. And finally we found a day when we could get it done. Lucky for me, Katrine also took some photos, so now I can show you at least part of the process. First thing\u00b4s first. The pottery I actually made months ago, and Katrine did the first raw-fire quite a while back too. So today started with putting glaze on the pieces. This clay is a very rough clay, half of it is sand (chamotte), which makes it very sturdy. Something it needs to survive the quick temperature-changes. We also use a special glaze for the rake-clay. And finally we are ready to go:<\/p>\n

This would be the before-picure \ud83d\ude09<\/p>\n

Katrine checking the oven. which can be made relatively easy from an old water-tank\u2026<\/p>\n

The oven is heated with propane, and it takes only about half an hour. There\u00b4s a peaking-hole in the lid, and when you can see that the glaze is starting to melt, it\u00b4s time to turn off the gas, remove the lid, and take the pieces out.<\/p>\n

First stop is a pile of sawdust. By leaving the piece in the air, the glaze cracks up. The longer you leave it, the more cracks. But you don\u00b4t want to leave it too long either, before burying it. The heat of the pottery ignites the sawdust, and you wrap it around the piece. This way you\u00b4ll choke the flames, and the sawdust will charcoal right into the pottery and make it black.<\/p>\n

After a while, say 10 minutes, I dig the pieces out again, and put them into water.<\/p>\n

\"_MG_6713\"<\/p>\n

I can\u00b4t believe nothing cracked! It goes directly from 960 degrees in the oven to 15 degrees in the air.<\/p>\n

Into the water. Making it almost boil\u2026.<\/p>\n

The color doesn\u00b4t look like much. Dusty pink. But just you wait and see \ud83d\ude09<\/p>\n

\"_MG_6720\"<\/p>\n

Scraping off the charcoal outside before taking it all inside again to give it a thorough round with a brush.<\/p>\n

And voil\u00e1! Aren\u00b4t they cute?! The quick temperature-changes makes the glaze all metallic.<\/p>\n
