Coldest Tempature You Have Raku Fired In?


Crusty

Recommended Posts

I fired at 20 below zero in Montana. No Problem. I was using natural gas, so no propane tanks to deal with. Got great color. There is an article about me with photos of those firings from 1997 in Ceramics Monthly. I think CAD has a photo or 2 from that as well under their raku glazes.I would not fire raku green unless you take it really slow, but that loses the spontaneity of raku.

This made me smile. I learned to raku in High School in February, wearing lots of natural fibre layers :).

 

It's a good idea to warm your next batch of pots up on top of the kiln while the first ones are firing if you have them all outside. If you take the bisque off the cold pavement and put them in a hot kiln, they don't like it much.

I am not touching the meat issue. the great thing about firing raku in the Autumn, is that people have already bagged up the leaves for you.If you are firing with green leaves, do you pick them off of live trees? Of course, you can always use straw or newspaper for reduction materials.

By the way, I also always wear natural fibers in layers. :blink:

TJR.

Neil,

I am living in the tropics right now and it rarely gets below 70 until January when it may dip into the 30s at night for a few hours on a rare evening. 

I miss the cold...really.

In Montana I started plumbing my raku burners to two tanks and this did eliminate freezing a lot. It could still happen but very rarely and not enough to get concerned.

I don't know how cold it was but one winter in Alaska I tried a raku firing and when I lit a match to light the burner the flame froze right to the match head!. I figured that it was too cold so I came back in and that's when the trouble started.  You see I was occupied with breaking down the kiln and I, without thinking, put the match with the frozen flame in my coat pocket. Well about ten minutes after I came back into the house, the flame thawed out and burnt a nasty hole in my coat.

 

Boy... I'll never do that again. :rolleyes:

how about hottest temperature? Today was gross and this week will get better until Thursday. It is still in the 90s.

Fired slabs today. Not as bad as August. Here is my tank setup. I have high temperature gloves good for 32 seconds.

I have lost too many slabs removing them with tongs. Much easier to just grab them. I have a video from today but have to get uploaded to my website.

Very pretty, I really like those a lot.. looks like the person climbed to the top and is taking a breather.. very neat... love the vertical scoring, made a perfect contrast ,, made the colors POP... Yep, you have been busy..

 

I am trying to talk my brother into Raku, he writes haiku poetry.. seems like a perfect fit..

 I have been to Laredo a few times and hit the border patrol , not fun when a German shepherd is circling your vehicle while the officer is asking where your from and if your a citizen ... guess its just another day at work for those guys.
