As I consider how I am going to 'improve my pottery' this year, I consider purchasing an oxygen sensor, however the price is a BIG consideration. I fire an Olympic torchbearer, an updraft kiln, using LP to cone 10. For the past 6 years I have used a sensor made from a Bosch auto sensor (Roger Graham directions). It has allowed me to get reduction in my kiln but it is spotty and I feel I have little or no control over it. I realize that weather conditions play a huge part in a successful firing and I am wondering if the cost of the new sensor will be justified thru better LP usage, more even reduction and more control over my (reduction) firings. Pottery is more than a hobby, but not a full time job, yet I do a couple shows a year and my pieces sell in a couple local stores - I see the payback as spread over a couple years.
Input from those with knowledge and experience with oxy sensors will be appreciated. I find only 2 on the market and cost ranges from $800-1200 so please give your best suggestions.
