Snail, I know this goes against all that you wrote that you can't do, but sometimes you just have to do it. I would get two five gallon buckets with lids and bring in the necessary materials, (it really won't cost you that much using simple glazes), and a triple beam scale, a proper strainer and just make 5,000-10,000g of two great cone six glazes. It will be an excellent learning experience for the students... get them involved with the weighing of the materials after you have explained the workings of the triple beam balance, sieving and mixing of the glaze. They will have a much better understanding and appreciation of the whole ceramic process.
Unless all of this has been expressly prohibited, that is what I would do. I can send you two great ox. cone six glaze recipes if you want, we use them where I have taught. You need ones that work well together, won't run and are beautiful, of course. If you can do this it will make you a star. Glazes are what the students (and the rest of us) relate to as much as form.
You are not using ^06 terracotta with ^6 porcelain, are you? Read like it from your post.
New again to the group (it has been years since I was on this group)

glaze with a CoE suitable for porcelain?
I'm frustrated to not be able to mix some up from

instructor comes back. I need to stick with their
system for now, and that means pre-mix. Any ideas?

David,
Our studio situation is a bit like Snails, but we do have some glaze
chemicals, scale and seives. We just don't have much space. I would
love your 2 glaze recipes if they are good "tried and true" ones. Most
of the students are working hard on throwing and construction and on
glaze application itself. A couple of really nice glazes would help
get away from too much choice of color at the beginning and focus on
how to get it on the piece still getting a nice result. You can send
them off line if you prefer.

David-
This is actually what I've decided to do. I just couldn't
let the students have NO raw-materials experience, so now
I'm combing my books looking for ^6 porcelain recipes with
not a large number of ingredients. I'll bring my scales
from home and have them make up at least one 5,000g batch.
>...You are not using ^06 terracotta with ^6 porcelain, are you?
Ummm-yeah, I am. Just about 10 pounds of each per student,
to experiment with. I was going to hold the line and allow
only ^6 materials in the studio, but I also want to give
them experience with more kinds of clay than the basic shop
body (a fine-textured buff stoneware), and I didn't think
the ^6 selection at the local supplier offered much that
was notably different at ^6 except the porcelain. So, since
the second-semester course is only eight students, I am
taking a huge risk and hoping they can be responsible in
their use and and reclaim of the earthenware (and that it
won't ever land on the ^6 firing shelves by accident). I'll
label a wedging board and a firing shelf just for it. I
may regret it, but I'm trying to give them a decent range
of experience. Next semester, I may think differently...
I don't expect to be rehired here, though - I'm only filling
in while the regular instructor is off for a semester.
No ^06 glazes, though. No space in the kiln schedule to add
a firing just for low-fire glaze. I'm trying to promote the
idea of one-shot firing and non-glaze surfaces anyway. It's
a way to minimize kiln usage AND expand their sense of what
ceramics looks like: not all just glazed pottery. We're doing
a cow-pie firing at the end of the term, though: great for
earthenware, cheap, and also within our technical capacity!

Dvid,
If you can send them online I would appreciate it very much...am in similar
situations with teaching.
