I was playing around with the eggs yesterday and the day before and accidentally discovered another lighting idea.
BGE recommends to light the lump and leave the dome open for 15 minutes. That doesn't work well for me. I had a bunch of accessories sitting the the egg mates when I lit the lump with alcohol. I closed the dome and the leg of the spider was in between the dome and base. I looked at it and thought why not leave it and see what happens. The had the normal spike and drop as it does with either alcohol, starter cubes or oil napkin. However, the egg light and got stable what seemed quicker.
So now to test and see what happens. I decided to clean out the ash and under the grate fill the fire box with fresh lump about 1" below the top of the fire box.
I again used alcohol and this time. After the light I put a 1/2" ceramic spacer (kiln stilt) under the handle between the dome and base.
In 4 minutes the dome had the usual spike to 750° then the draw down and slower raise o 400°. This happened in just under 4 minutes. I adjusted the vents to hold 400° and there it stayed for 30 minutes until I shut the egg down. When the egg had cooled down I used the same lump no stirring and lit with oil and paper towel. Again, a very fast light.
The third test was with MAPP. I lit in 3 places and put in the spacer and again got the egg more stable.
I was very pleased with the performance of the light and getting the egg stable.
The same test on my medium was slower but I think that is do to the Undersized firebox and small fire ring in my particular medium.
