Topics I've Started

Blue Rutile

22 December 2013 - 01:43 PM

I handbuilt a bowl and airbrushed it with amoco blue rutile(cone 5) potter's choice on red stone cone 5 clay.  This was my first attempt at airbrushing, and the glaze went on smoothly without spotting for 3 coats. there was no hint of blue after firing. There was also fine spatter on the shelf after firing.   From reading past posts, I realize that the piece had no blue because the glaze was too thin.  Two questions:  1) Can I heat the bowl, reairbrush with more blue rutile and gain some of the blue variation I was hoping for? 2) How can you tell when a glaze is thick enough when you airbrush?  Thank you for you knowledge and willingness to share.


Older Kilns

02 November 2013 - 05:13 PM

I was told when I got my kiln to leave the top hole open when I fired to cone 04.  I did a test to see if the kiln would fire to cone 5, and according to my records, an empty kiln turned on high took about 3 1/2 hours until the kiln sitter fell.

 

Now I'm going to fire a cone 5 load, and I am wondering if I should close the top hole also.  The kiln is well vented, and the work is dry.  I did 1 hour on low, 1 hour on medium with the lid open about 5 inches.  Now the lid is closed and two of the three side holes are closed.  Would closing the top hole heat the pieces more quickly?  Would that be a good thing or not?  I'm using Amoco Potter's Choice cone 5 glazes on Little Loafers.  I'm not sure how long this cone 5 load will take, but the 04 loads take about 2 1/2 hours after I have turned the kiln to high.  I'm not sure how long to set the sitter for.  Any help is appreciated.  Thank you.


raising my wheel

07 May 2013 - 05:49 AM

Several people have mentioned throwing with a raised wheel. Since this sounds less wearing on the back, I'm wondering if some who throw from a raised wheel could give guidance on how the height of a raised wheel relates to their throwing positions. I could easily manage a platform to raise the wheel, but I don't have a clue where to start with dimensions. I have an older Brent model B wheel, and wonder if there are other adjustments that would need to be made. Thanks for any input.

Old kiln elements and relay switches

14 March 2013 - 04:31 PM

I have an old SnoIndustires kiln model P22 with a spacer blank in the middle. Yesterday the top elements stopped firing, and my husband tells me that the electricity is going into top switch on the kiln, but not out. Does anyone have an idea where I can purchase a box for the top connection for this model? The other option is a new kiln, and I would love to have a digital model at a reasonable price. Any suggestions for home use kiln that gets fired 10-15 times a year? Thank you for your help.
