Hi Susan,

I am so sorry to hear about your knee!!!!  Hazards of winter uggg.  I hope you will be able to get back into your studio soon.  I use various clays.  Recently I have been using a lot of cone 6 porcelain.  I get my clay from Tucker pottery supply-we have a distributor for pottery supplies here in Ottawa.  I am so thrilled, I mixed up variegated slate blue from Ron's book and it looks like the book.  There were some comments about the rutile changing the colours so I subbed half titanium dioxide.  I am very excited as I now have about five really solid dependable glazes.  I keep tweaking the others, more water, less water, etc etc.  So as I said at the outset I wish you a speedy recovery!!

Hi Suzanne - I am a fairly part time potter as well as I have a couple of businesses outside of the claywork.  I managed to break my kneecap two days ago while skating on a local lake, and with a cast that runs from my ankle to upper thigh, I am going to be pretty housebound for a bit!  Hopefully I can get into the studio next week as I haven't had much time in there this last month.

What kind of clay body are you using?  I try to fit a bunch of tests in every time that I fire. I am only using a porcelain body at cone 6, but next time I get a change I am going to pick up a darker body as well so that I can run any tests I do on more than just the porcelain.

Thanks for sharing!!!  I am a very part time potter, when I retire (elementary school principal) I will shift to being a full time potter.  I have so much ware that needs to be glazed and fired!  I am trying to develop an inventory of glazes.  I have taken a course with Ron Roy, but these things take so much time to develop.  To make a long story short, it is very generous of you to share your information and helpful to people like me!!!

Hi Jan - This is a very simple glaze from Digital Fire's tests of Alberta Slip - which is a very effective substitute for Albany Slip.

Alberta Slip Rutile Blue for Cone 6

Alberta Slip - 80

Frit 3134 - 20

Rutile - 4

These mugs are thrown from Plainsman Clay's M370 mid-range porcelain body. where the glaze is thin or on high spots, it is more of an amber colour. It takes on a purple tone where thicker and a powder blue where it pools.  Where it overlaps the liner glaze (Ravenscrag Black) it is a deeper blue. On a light buff stoneware body it is still amber coloured where thinner, and more of a powder blue where it is thicker, but lacks the purple tones.

Wow, what beautiful glaze colours. Love these. Is this the same base glaze as the green mugs with colourants added Susan? Thanks.
