I like to use Veegum T to fix short batches of reclaim. I keep a tub of hydrated Veegum next to the pugmill. After each batch is mixed, I test for shortness, and if needed, put in a small scoop full of the hydrate Veegum and mix some more. Veegum is expensive, but it doesn't take a lot to fix a batch of clay.

This would probably work, but the crazing you will get with most commercial crackle glazes will be much finer than the example photos you posted. You will need to go over the pot with India ink after firing to get dark color into the cracks.

Wollastonite lumps revisited
Piedmont Pottery replied to Piedmont Pottery's topic in Clay and Glaze Chemistry
Wollastonite has a much lower LOI than whiting (1.6% vs 43.9%) and has a lower thermal expansion coefficient (9.0 vs 14.8) (data from DigitalFire). Wollastonite also provides silica in addition to calcium. My glazes are high silica/low expansion by design, and wollastonite gets me there. And finally, Wollastonite cost me $0.59/pound the last time I bought it, whereas whiting cost me $1.17/pound. I'm sure I could rework my recipes to substitute whiting, but there is a certain amount of inertia involved in doing that, as I'm generally happy with the way my glazes are behaving on my clay. -

Some time ago I posted about challenges with wollastonite clumping. I have now found a process which is helping with this issue. I utilize one of these flour sifters when weighing out the wollastonite. I sift the material directly into a pan on the balance until I have the necessary amount. It's pretty low tech, but it works. Perhaps not feasible for large-scale batches, but I'm usually making 1-2kg batches of most of my glazes, and it works fine for that.

Moving a Duncan DK 1029-1 and bringing it back to life
Piedmont Pottery replied to Bubba's topic in Equipment Use and Repair
If the controls are corroded you may want to look at an external computer controller. That is what I did on my old Duncan 1029. It will cost more up front but will really help with more consistent firings. You will have to drill a small hole for a thermocouple to go through. all the infinite switches are set to Hi, or bypassed altogether. I did leave the kiln sitter inline to have a failsafe option. -
Peter Pugger works only sporadically
Piedmont Pottery replied to Diane Gwilliam's topic in Equipment Use and Repair
I haven't had that problem with mine, but I've found Peter Pugger technical support to be very friendly and helpful when I've called about other issues. They should be able to offer suggestions. -
Will your program accept multiple log files for long firing time programs? I often have two, sometimes three log files per firing, depending on the program. Also, I'm hoping that your program will be compatible with first generation Genesis log files. I'm really looking forward to your finished product.
