Thankyou so much Mary Kay,
I was usually giving a soak at 1180 when casting to help the mold and glass to get to a temperature to avoid cavitations in my SKUTT casting kiln with great success there, BUT : in the flat kiln with only top fire I was worried to go to fast, as for years I did not, but I MUST re-train myself and listen to the experts who are doing numerous tests!!!!!!! (thankyou to you all at Bullseye!) (I really think I am trying to do tooooo much in these old kilns and ask the glass to do tooo much as well .(I TRULY want a new kiln
is really where I want to go. The Pearl 56 is just what I really need
to be able to achieve what I really want to achieve.) I purchased the system like in Tech note 7 (well the hand held one with 2 thermocouples) so I hope to have a new lid for a kiln with bottom elements also soon when it is complete; so hopefully I can really do some testing and measuring and ghost blanks and all. I feel I am back at the beginning of a glass adventure and even though I am struggling with my equipment , I am still enjoying the glass. It is NOT good tests though to keep breaking things (a new thing for me this past year!) so I must just get the new equipment. Bottom line I guess. Thanks again.
