    Benzine got a reaction from liambesaw in Only glazing half of mug, susceptible to stains/moisture?   
    I'm guessing it was first used by a manager, to slowly sip, while critically looking at their employees,  "Yeah, I'm going to need you, to get  those manuscripts turned in, before you leave today..."

    I bought a power rotating   powersponge to clean slip seams and glaze bottoms  years ago. The maker has since died. The thing sits over a 5 gallon bucket and spins slowly . Its a 10 inch or so wide sponge that picks up clean water and flushes off the slip or glaze on sponge as it rotates. Its a simple tool that I use when doing say my wall fish and needs smooth glaze edge. I use it very little as a hand sponge is pretty fast.

    @liambesaw @Benzine I've found that if you apply Sherril's Scarlet Kidney of Shining to the projected exposed parts at leather hard, sponges gain a +5 resistance to shredding damage. Your gaming table still will still likely appreciate a coaster.
    For those non-Dungeons and Dragons players, burnish the exposed part with a little red rib to smooth it out if you're worried about causing damage to sponges or tabletops. Work clean to keep the feet clear of burrs and crumbs, and give your pots a quick pass with some 220 grit wet/dry sandpaper, used wet, after the glaze firing.
    My clay is fired to around 1% porosity or less, so I have no trouble leaving exposed clay on the bottom 1/4 to 1/3 of the pot. I haven't tried to test where the line is when a mug will break more readily if too much is left unglazed. I know if it's only lined, it's a lot more fragile.

    Only weakness is slight structural weakness and +5 damage to sponges. I do a lot of my bowls this way for extra grip and tactile texture

    Its best to clean them as you glaze them.

    Piece of wet carpet or stiff sponge in cat litter tray or smaller.
    Wax, glaze, swipe across wet carpet/ spongr in tray or rotate a bit on wet carpet in tray.

    I buy them from Clay-King.com. If you sign up for their email newsletter, once or twice a year they have a sale where you can get pints as low as $6-7. Plus they're generally too thick in the bottle so you can water them down at least 25%. That's really cheap compared to Amaco Velvets. Their color palette is not as extensive, but you can do some mixing to get more colors.

    I use Speedball. It's really cheap compared to Amaco and Coyote, and the colors hold up well at cone 6 for the most part. The red and royal blue have some issues with bubbling at cone 6, but I'm working on fixing that.

    Look up the msds of the specific glaze.  You won't find the exact ingredients, or exact percentages by weight, but you'll see a range which might be helpful.

    The best you can do is look at the MSDS. It will list ingredients to a point, but won't give accurate percentages of any of them. They're meant to be pretty vague so that the manufacturer doesn't give away the formula. Their purpose is to inform the user of possible hazards so they can handle the material safely, and for medical treatment in the case of mishandling it.

    +1 for soaping the brush before using wax resist. Dampen the brush and work some dish soap or hand soap  thoroughly into the bristles, right down to the ferrule. Try not to get it too wet or bubbly, or it's hard to point the brush. Even the crusty gross wax resist rinses nicely. I've  been using the same artificial sable brush for wax and other things for about 8 years now.

    Load your brush with dish washing liquid...thick stuff before dipping in the wax resist. Washes out easily.

    I threw a wax pot and keep the brush inside.  It's just a stout closed neck bottle.  As long as the brush doesn't dry out, it won't die.

    The wax that Ceramic Supply Chicago sells will rinse out of brushes with just water. Awesome stuff.

    Ya know you have two problems, process and business. I would look for slip casting classes. While pottery classes for folks working in ceramics is a good thing it sounds like this is a slip cast business so a pottery class may have very negligible value if you are planning to keep this business going as is and may well just get you all confused about it all. You are not trying to decide on the direction to go with pottery,  you want to know how to use the stuff you have. A generic pottery class would be fun and certainly dial you in on working with clay forms but slip casting is not the same thing and the class may not even cover it at all or just clip past it quickly and running electric kilns may also not be covered in any kind of depth. 
    If I were you I would go on an information blitz, watching every you tube video I could find on slip casting and order any books you can find on amazon. You already have all the equipment so using the that information you should be able to get going. Sometimes it is good to just go at it. If she has not fired those kilns in a very long time it might make sense to have a kiln person or at least an electrician check them out for safety before you start using them. 
    Has the business been running right up until now? I mean are clients expecting delivery of products or is just just a case where she had run this business in the past so all of the equipment is still there? You mentioned a Christmas tree mold but it's mid October so unless you are planning to man a booth at some Xmas shows Xmas buying by businesses I think is long over unless she has some orders already.
    Good luck!

    You're asking for an awful lot of info, more than we can give you here without pages and pages of typing. It would be good if you could pay the previous owner to spend a couple of days walking you through the entire process. There are a lot of variables that will be specific to your studio depending on what types of equipment you have and what type of slips and glazes you are using. In ceramics, hands-on experience is the best teacher. It would also be good to take a ceramic class from a local art center or community college where you can learn about working with clay and firing kilns. You may not get any experience with slip casting there, but you will get a lot of good general knowledge about clay, glazes and firing.

    Holy cow mark, you never stop do you?
     
    I spent this weekend building a work table / fume hood for my work with soluble salts and lustres.  Sulphur, and mercaptans (thiols) are part of synthesizing a lustre overglaze and these are some of the smelliest compounds on earth.  I did an open air run of some palladium mercaptan a few weeks ago and you could smell it from blocks away.  I decided instead of subjecting my neighborhood to a somewhat regular barrage of rotting smells that I'd go ahead and do it proper.  A 350 cu ft per minute fan pulled through an activated carbon filter rated to match.  It won't get rid of the smell entirely but will trap a lot of it.
    At least that's the hope.  This combined with an acid gas face mask will hopefully keep me better protected from hydrogen sulfide and other byproducts that are unhealthy to breathe as well.
    I know it's pretty janky as far as lab equipment is concerned but it actually works so I consider it a win!

    Yeah as soon as they are stiff enough to support being flipped over they get flipped over.  I did speed dry them outdoors with a fan so I could wire them off and reuse the bats (I only have 36 bats).  Worked out pretty good and I only killed 3 of them while trimming heh.

    (For the best results as far as having the slip fit the clay body, you should make the slip out of your clay body.)
    yes this is best if you want whiter use a porcelain clay that shrinks the same as your clay body (same  or close shrinkage rate) and make that clay into a slip.
