I am befuddled with a job involving Ceramit. I am making a large 3"
Star shaped plaque that will have Ceramit in certain places. I am
matching colors from another similar plaque. I bought the ceramit
kit from Stuller with basic colors, and some other colors from a
local supplier. The problems are two-fold. The green bubbles when
it is curing at 200 degrees. Even if I do very thin layers, no
bubbles when I put it in the oven, filled with bubbles when it comes
out. The second problem is colors staying the same before and after
firing. I carefully mixed a light blue color, did test strips, but
when I fired it it changed color dramatically, from an aqua blue to a
dull grey blue. After many test strips and attempts, I finally had to
burn it out and start over. The oven is kiln with two pyrometers so I
don’t think I am firing too hot. Also, the blue color separates when
fired so I get a dull grey with little marbled areas of dark blue,
even after mixing well in my little Dixie cup.
I have checked the archives, and it seems the two main threads cover
types of enamel substitutes or that ceramit seems great. Nowhere can
I find how to troubleshoot it. I am pretty certain we want to stay
with ceramit, but I just need some advice from someone out there who
has been using it!
Thanks in advance!!!
