I use RIO to sign all my work. I mix 100g RIO with a small amt of ball clay and Gerstley Borate. This keeps it from smearing when handling greenware and it looks nice when fired.

My little 12 cubic Burman updraft has 6 burners pointing up like yours-(Its almost to cone 10 now) and I do not even put cones on bottom as its always hotter there and I fire it only with top cones.I load all the need heat glazes on bottom and cool glazes on top and its worked great like this for past 20-25 years.I know its always a cone or more off on bottom and just accept it.

Sage advice as always from you. That is probably where I will end up as soon as I figure our which glazes thru at each temp.....

A solid thin piece of soft brick or hard behind cones works like a post -anything to set the cones off visually.
Spiting the flame with a post may or may not help
Darker glasses will help as well as a laser pointer (or so I'm told)

I actually have a laser pointer, so I will try that as well.

You don't want to put anything directly in front of the burner port. Assuming we're talking about burners going in horizontally, there should be a target brick in the middle of the firebox that breaks up the flame.

Actually the burners are vertical - coming up through the floor - right in front of the bottom peep. The idea is to put a post or refractory across the middle of the port so that you are not blocking it - just moving the flame to each side.

I also heard today that a local teacher user a rebar pole and he touches the cone when he can't see it. This seems to make the cone easier to see. I am going to try that next time.

Try darker glasses, decreasing the reduction for a minute, or setting a post right behind the cone pack.

Thanks Neil. I will try both. Someone else suggested putting a kiln post across the burner port to split the flame. Have you heard of that?
