In Topic: Robin Hopper's Mocha Diffusion-Base Slip

18 December 2014 - 04:36 PM

I will have to try the tobacco and the soda ash. If Min doesn't respond to this thread I will PM.

 

I did try letting the sheen go off of the base slip before I put the stained vinegar on it. Absolutely nothing happens when I do that. I don't even have a little fragment dendrites around the edge of my blobs. In the Robin Hopper Video, it looks like the base slip is very wet.

 

Thanks

I think you are right now that I think of it. i think the slip has to be wet. you put some kind of stain in the tobacco juice like iron ox., and it forms these tree like structures. Saw it done about 20 years ago, so i may not have it right, but I am very sure that it was tobacco that they used. they were pretty cagey about it at the pottery I visited in the states, calling it a rare herb. i laughed, because I knew tobacco when I saw it.

Larry;

I have not done this myself, but i have seen the technique done in England and the Southern states.

you dip your leatherhard pot in white slip.

When the sheen has gone off, you pour on tobacco juice made from old cigarette butts. This is the secret ingredient-very acidic.

Remember, i have not practised this myself, but I am very sure that this is what they used.

In Topic: How Many Kilns Needed?

14 December 2014 - 11:52 AM

This is the last week before Christmas. Two week break, then a week of classes, then exams. So, you really want to have everything fired up before Christmas. Then students are working in their sketch books and writing a one page reflection on their projects. When i say;"We are cleaning the room on the last day, no one shows up, which I love.

Oh, yeah! I teach high school. If I want to keep anything good, like new clay, I leave it on the floor. No one touches it. I could probably leave brand new brushes there, but the custodian would sweep them up. Any pencils dropped on the floor get tossed by the custodian.

I wouldn't have students writing for a month. I would introduce a clean unit like pencil crayon drawing. Or you could make plastecine landscapes on matt board.

At my high school, we have 7 classes of art in each of two semesters,for a total of 14 classes. Two full time art teachers. We do 5 units per class. Only one clay unit in each grade. The other units are drawing, painting, print making, collage or something else.

We try to run our clay units in the winter rather than in June as our 50 year old school has no air conditioning. Actually the principal and the secretaries have air.

I have the biggest Cone Art kiln you can buy. The other art teacher wheels her stuff to my room for firing.

I don't know if I would want to teach ceramics the entire semester. Can you mix it up with other media, or were you hired as strictly a clay person? Our school has 1300 students. Art is an option, and not a required course.

I don't think you should buy another kiln. I think your program is big enough.


In Topic: Help! Accidentally Glazed Together My Pieces

I use an old wooden claw hammer handle, and gently tap around the lid. Sometimes, you can put jars in the freezer overnight, then run hot water over the lid while tapping. If you know that you have glaze on the gallery of the lid, it probably won't come off.Then you smash the entire thing and start over.
