| Shot glasses, cork pots and the first of 4 sun sculptures to survive a bisque fire! |
The color of these pieces will look 100% different after they are fired, of course. I will post an after picture eventually.
When loading the kiln for a glaze firing, there are several things that need to be considered:
• Pieces cannot be touching each other or the kiln floor/shelves - the glaze will melt and they will stick together. (Unlike a bisque where you can stack pieces and they will fire fine.)
• If there is glaze on the bottom of a piece it must be dry footed
• All beads and ornaments must be wired and hung separately
• Space must be used wisely, like-sized pieces should be placed on the same shelves in order to maximize the firing.
There's other stuff, but that's really all that I had to worry about for this one,
It takes quite a bit of time to wire hang beads, but it is the best firing technique I have found. As you can see in this picture of my second shelf, I hang the beads on small metal posts. I also have pendants and color sample blocks on this shelf.
My ornaments are long pieces of clay that have been twisted to resemble an abstract icicle. I could lay them down and dry foot them but that would leave a few sharp spots on their exterior that I would have to sand off and they would be pretty noticeable. So I had to find a way to hang them...
There is a difference between the placement of the pieces on the shelf in the last two pictures, the stuff below the ornaments had to be moved around because a few of the ornaments hung too low and touched them. When removing the ornaments to move things around, one of the posts fell over - knocking a pendant down to the kiln floor. Not cool. I tried taking some wire to fish it out but in the process I knocked a shot glass off its dry foot. I had to remove the second shelf to get the pendant out and reset the shot glass. This happened like 5 times.
Remember when I said to notice the kiln sit on the left side of that picture? Here is another shot of it from the outside of the kiln.
When I finally had this f-ing thing ready to go I about did a damn cartwheel. I turned it on low for two hours, bumped it up to medium for an hour and when I checked it after that it was already shut off. No way does it only take 3 hours to fire cone 05, unless it's a high fire which I never do.
You're not supposed to open the kiln until it has cooled because you could wreck what is in it by changing the temperature inside the kiln so abruptly. I however, couldn't resist. I carefully opened the kiln with a hot pad to see what the hell was going on and I wish I would have taken a picture to show you what had happened... The metal rack holding the ornaments warped - a lot - making all of the ornaments shift and tip over to touch each other and the stuff below them. THANKFULLY one of the ornaments also knocked the cone out of the kiln sit, turning the kiln off before it got hot enough to melt the glaze and ultimately wreck everything I've been working on for the last month.
I still need to come up with a high temp metal solution to hang ornaments from... but at least I have the option of re-firing and saving everything. Needless to say I'm glad for that but holy hell is this ever frustrating. Hopefully I will be posting finished product pictures in the next couple of days and be telling you all about the ingenious solution I came up with to fire the ornaments successfully. Until then, please cross your fingers.
