So I have been in this class a few weeks now. I know that Orion likes to include projects that relate to bowls. I am feeling I would like to experiment before it becomes a request.
Hmmmmmm. I rolled out some wax until it actually reached across our kiln casting table and then I began to wrap it in the shape of a bowl. I added 2 handles of similar fashion.
I was hoping that I
could make a mold by which I could reproduce this particular bowl. By the time I had had
the procedure explained to me by different people, I settled for making
1 such bowl of its type.
There were 2 other bowls that Orion showed to make by pouring melted wax into a bowl formed from plaster. As the wax cooled, I could pour out the excess wax leaving a wax bowl the thickness of which was determined by how long it took me to pour off the excess as it was cooling.
The interesting thing about them was that maybe I hadn’t allowed for enough melting time in the firing. By the time I began to smooth out the edges on the grinding belts the reservoir on the bottom was crumbling (I would have liked to preserve it).
I wondered about the possibility of refiring this same bowl with more glass. Todate that has not happened.
Both of these 2 colourful bowls turned out
fragile. Below I have included the program that was used for all 3 in the same firing.
I am still having thoughts about how I would like to use them–or if I should melt them back into flowing glass and make the colour diffuse with clear!
By the way, before I go to the program, I should mention that I used a flower pot to
hold glass as a reservoir. It slightly cracked from the last firing, but seemed to survive this one, also. It has now been retired.
Kilns #1 & 4 – scheduled firing – October 3 at 3: but didn’t happen until Oct.11 @ 12:45 in Kiln #1.
I am using soft glass in this firing — as I have done so far. The kilns are accumulative in how we program the hours (and minutes) and the temperature is quoted in Celsius
- 3: hrs ^90 degrees
- 12: hrs ^110 degrees
- 24: hrs ^120 degrees
- 30: hrs ^600 degrees
- 32: hrs @600 degrees
- 32:01 hrs ^850 degrees
- 40: hrs @850 degrees
- 40:01 hrs 516 degrees
- 55: hrs @ 516 degrees
- 80: hrs 390 degrees
- 100: hrs 50 degrees
Ultimately, I think that both of the coloured bowls lacked sufficient glass. So I am going to take Orion’s advice and include more glass in the reservoir for melting in my future melts to see if that helps.
I might also consider using higher and lower temps to explore the possible textures that could evolve.
