How Strong Is Unfired Clay?
Stellaria replied to JenniferG's topic in Studio Operations and Making Work
Pretty sure the OP just has a couple pots they want to keep, and isn't looking to make further quantities of unfired ware? -
How Strong Is Unfired Clay?
Stellaria replied to JenniferG's topic in Studio Operations and Making Work
If you don't bump it against anything, or get it wet ever, it will last just fine, like any lump of dried mud you'd sit on a shelf. -
Cool. You guys made sunscreen. Break out the mortar and pestle!

I look forward to seeing what you manage with your experiments I'm just waiting for the rest of my red ware to get ^6 fired, then they'll get the milk treatment. I'm excited - I used texture stamps on some of them this time.

^6 test tiles have been added to my Milk-firing gallery. Starting with fully vitrified clay rather than bisque is definitely the way to go. I got way better color, and a much more glossy and water-resistant finish without having to wax at all. I still have a lot of fine-tuning to do to get my technique down reliably, and I'm sure I'll think of other variables to test in the future. But for now...I like!

Again, left is dunked, right is sponged. I definitely like the color of the dunked piece better. Next time, I'll make sure the cream is well-blended into the milk before dipping, and I'll just have to watch it a LOT closer while pieces are in the oven so I can catch them before they completely blacken. I like that the tiles really did get a kind if glossy, water-repellant finish to them, even without waxing. -
Experimenting with the Ukrainian method of washing a fired pot in milk, then bringing it to about 600°F and holding it there until the desired color is reached. This bowl was thrown from Runyan K-4 Multi-Purpose Red Brown Body, and fired to cone 04 prior to milk treatment. Following the milk fire, it was treated with a generous coating of beeswax and olive oil (2 parts wax, 1 part oil melted together) then heated to 200°F to allow the wax to soak in. Heating it released all the little bits of terry towel fluff that got caught in the wax upon application, and they just brushed off with a light buffing.

For this test, I used tiles of the same clay fired to cone 6. The left tile was dunked into very creamy raw milk and air-dried three times, and the right tile was sponged down with the same milk and air dried three times. They were then placed in the oven, and then heated to 550° F. I expected it to take a while, so I waited about 15-20 minutes before checking on them. The left tile was a glossy BLACK. The right looked about like it does in the photo. I decided to see if any of the carbonized milk could be scrubbed off with a scrubby pad and water, and what you see on the left is the results of that. The areas that scrubbed the barest were the areas where cream streaks stuck to the ceramic. I suspect the cream prevented the more sugar- and casein-heavy milk from adhering to the ceramic body, which kept it from carbonizing in the fine texture. -
For once, I don't feel like I was hit by a truck on Monday morning! Let's see if I can motivate myself to get the necessary cleaning done to swap my sewing room and pottery workroom around. I'll have so much more space!!

Impression made with the Julienne Tomatoes stamp. The tomato gets painted with underglaze, is waxed over, and then the piece gets dunked in whatever glaze I'm using. It's a pretty satisfactory result for such a simple, shallow-lined stamp. -

Bear paw print stamp and impression, created for a friend who goes by the name Bjornsson. It helps to keep his dishes differentiated from the rest of my stuff. Carved from hardwood with a dremel. -

Give it a try. The least you could get is a bit of wasted milk and some browner pots. I'm waiting for some test tiles to be taken to ^6 for me to try the milk process on, to see if they will take on enough of the milk to make any difference. Normally I'm not a very experiment-y kind of person, but this has me wanting to play with possibilities!

The reporter can't write for crap and she got virtually NONE of her facts right, but hey! Our Clay Club is in the newspaper! http://www.petoskeynews.com/graphic/clay-creations/article_d8271924-61d9-5be9-a0ab-7d6ca156f662.html?TNNoMobile

Yeah, the kiln I have is so tiny, if I was going to spend any money I'd just buy a bigger kiln Thankfully, my home oven worked great for this technique. But thank you for the info!
