I am looking at getting a kiln to HT my knives and I am looking at the Olympic Model 1823FL, the Evenheat KO 22.5, or the Evenheat KF 27. When I said I was looking at getting a kiln my wife asked if there were ones that I could HT my knifes in and she could do some pottery work in witch is why I was looking at the Olympic, because of the greater volume. I have herd good things about the Evenheat but I have not herd much about the Olympic for HT. I would like to know what there ramp speed is and how long they take to get to 2000f. Also does the ramp speed of the kiln increase if you take up some of the volume with firebrick? Thanks.
