Pres Posted April 22, 2015 Report Share Posted April 22, 2015 I was loading a kiln load up today, glazing as I went, loading each piece as I usually do into the kiln when finished with it. I set of my pre waxed taller pieces aside, working on the patens(plates). I go through a series of dip glazes, sprayed and poured glazes, and some atomized on stains. I then finish the foot ring by using a damp sponge on the foot rings of the patens while on the griffin grip. Chalices are done much the same, in batches of 2 or 4 to match patens. I placed the lid on the kiln(mine is not hinged, but has two handles) leaving a little space up top for early venting. I also leave out the peep plugs on the top two layers. All kiln switches were turned to 9 o'clock which is 25% on my switches. An hour later, I have closed the lid, but leave the switches at the same position. What simple test could I use to tell when to start up the regular firing? This is for the newbies out there, and the experienced folks also. I have been noticing questions involving, shivering, spots on kiln shelves, and other things that this test could help alleviate. Answers folks?

Chris Campbell Posted April 22, 2015 Report Share Posted April 22, 2015 Do you mean ... when is the excess moisture gone? Hold up a mirror and if it fogs, don't ramp up. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted April 22, 2015 Report Share Posted April 22, 2015 If you are talking about moisture as Chris asked, I have used a mirror or a jar by the cracked lid to see if there is still moisture coming out of the kiln. Marcia Link to comment Share on other sites More sharing options...
Pres Posted April 22, 2015 Author Report Share Posted April 22, 2015 Yeah, you got it. I just hold my palm to the peep, and if it feels damp, no go. A lot of people start the kiln prematurely after glazing immediately. Really bad idea with glaze spits. At the same time, I always use if with a bisque load to make certain I get the atmospheric water out of the pot before moving the temp up. Link to comment Share on other sites More sharing options...
Pres Posted April 22, 2015 Author Report Share Posted April 22, 2015 Another good question: What three type of water do you get rid of when moving from wet clay to glaze fired ware? Link to comment Share on other sites More sharing options...
clay lover Posted April 23, 2015 Report Share Posted April 23, 2015 Physical water, chemical water and atmospheric. ?? Link to comment Share on other sites More sharing options...

Marcia Selsor Posted April 23, 2015 Report Share Posted April 23, 2015 Are we getting close to water smoking? Link to comment Share on other sites More sharing options...
Pres Posted April 23, 2015 Author Report Share Posted April 23, 2015 Clay lover got the answer, but it is often called Mechanical water, or water of plasticity, then the other two, atmospheric that goes in the bisque first then Chemical water, last to got in bisque.

Pres Posted April 23, 2015 Author Report Share Posted April 23, 2015 Too whacky last night, I turned the glaze load off at 3:30 am, ^6 1/2. Link to comment Share on other sites More sharing options...
