Re: Jen ken 15" kiln relay question
The side and top elements should turn on/off at the same rate. The temperature controller will send one signal to both relays at the same time. If one relay is not cycling at the same rate as the other, then there is a problem. As far as turning on "as strongly", that depends on the resist...

Re: Help buying a Controller
I had the choice when I set up my studio of saving some money and going cheaper or going with Digitry. Worth every penny. When people claim a ramp rate in a kiln schedule, that assumes your kiln can heat and cool at those rates You are much better off with a controller like Digitry which will do th...

Re: Help buying a Controller
Not sure if you've received the Digitry and realized it yet, but you're still going to need a power relay of some type (mercury, electro-mechanicl, or SSR/SCR) to use it with your kiln. The controller Paragon quoted you on has an integral power controller, usually an electro-mechanical relay. The GB...

Rochester is about an hour and 15 or 20 minute drive, depending on driving speed (watch for State Troopers parked under overpasses). The airport is about 90 miles from Corning and is much larger than the little one at Elmira (which is 8 or 10 miles from Corning). As you said, it is a nice drive from...

Hello Brad S., I second your remarks about the library and the area. I go to Corning often also, but I am an hour east. I also want to put in a plug for the other waterfalls in Ithaca- Tremain, and Buttermilk, but especially Tremain, which has an upper and lower section. The Tremain waterfalls have...

A couple of other things that should also be considered for those traveling to Corning and who have some extra time for exploring are the Rakow Library and Watkins Glen State Park. The Rakow Research Library is part of the museum and is worth planning at least an extra day for anyone with an interes...

All this talk of 20 year old thermocouples has me wondering about the liklihood of mine failing......this kiln is only 2 years old??? Not that anomolies don't happen, but doesn't that seem awefully young for a serious drift? Lisa P.S. 1550 got rid of the sinkholes but overcooked the piece, it was d...

Like Brock, most of my K type thermocouples aren't sheathed either, and they are all originals, varying in age from between 6 months and 20 years. That's a large part of why I said I don't think sheathing matters much in an uncontaminated atmosphere. But although I have made a few trips to 1800 degr...

Hi Emma, Sorry about the delayed reply. The standard way of getting oxygen into a glass melt is by using a nitrate, e.g., sodium or potassium nitrate. Unfortunately, in your case this really isn't feasible because it will both introduce bubbles and change the expansion of your glass. You could attac...

Assuming that the BE violet is colored with manganese oxide, which seems like a reasonable assumption (Lani?), your color problem is probably due to reduction. While manganese oxide is the most common colorant for violet glass, it is very sensitive to oxidation/reduction color changes. Manganese pri...
