glaze question - carib blue problem???

Could the person who posted the recipe for Dennis Carib blue please check your
recipe and maybe repost. I think something may be missing either in your
post, or how I copies the recipe. I ran the recipe through my Insight software
and it showed way too high with alumina and silica for a cone 10 recipe. The
silica was 6.76 and the Alumina came out 2+
Here is the recipe as I copied it. I may have copied it wrong or missed an
ingredient.? :-(
This recipe also doesn't total 100???

Dennis Carib Blue cone 9-10

28 Custer Feldspar
4 Whiting
3 Tin oxide
3 Bentonite
15 Illmenite (I figure that this must be an error, either mine or the posters,
and is probably 1.5)
38 EPK (based on the total of this glaze, this much epk would put the clay at
40+% or the formula.
1 Cobalt (I'm assuming oxide???)

Thanks for clarification.

Warm regards,
June
