  1. I thought I’d share a trick I picked up for separating mud from water while running a recirculating power sluice looking for gold. The same system seems to work well for the sink drain in my studio, it works off of some simple hydraulics and siphons water from tank to tank giving the heavy particles time to settle before exiting the tanks. I used three 5gal trash bins and connected them using 2” ABS, each connector was made from one 2” U joint, two 2” elbow and two 8” long nipples. The drain is one 2” ABS adaptor and a 2” sink drain gasket and one 24” long ABS nipple, everything glued with medium ABS cement. The elbow on the bottom allows you to fill the tubes and submerse them into the tanks while maintaining the siphon in the connecting tubes. Total cost for everything from Home Depot was under $50 and build time under an hour. The system easily handles the volume of the water as it drains directly down into the first bin and when the bin is at capacity with solids it is simple to remove, empty and replace. The design allows infinite number of settling bins and any size and shape of container pretty much can be adapted to work, so I think this could be made from a variety of free parts.

    Simple DIY sink clay trap

    Lol, if only my dirt had enough gold where that was a factor and actually the golds never supposed to get that far as the settling tanks are only for the soil/clay suspended in the water when the waters to dirty the fine gold won’t settle fast enough in the sluice and then it will be lost in the tailings.

    Simple DIY sink clay trap

    Bill, I’m sure you are right and I can adjust as needed, good thing is the way it is now when not throwing clay I can convert my clay sink into a mini clean-up gold sluice.

    Simple DIY sink clay trap

    I was amazed how well this worked when I saw a guy using it moving water between tubs, some ancient technique for watering crops or something like that . JohnnyK is right and this isn’t for everyone and if I was concerned about an accidental overflow I would drop the whole thing down into a water tight box and add a p trap at the end. I’m using it inside my studio this way for now and my clay water is diverted outside into the garden and waters the hedges so the traps not needed. The water level between the first and second tanks stays very close and the third tank is slightly lower. I think the large diameter pipe has little friction loss at this volume so the siphon action with atmospheric pressure keeps it fairly level. The tubes are 4 or 5 inches off the bottom so I think it will hold at least a gallon or two of sediment.
  5. A word of caution, I ordered some clay and glaze to test last month and placed an order with the big ceramic store for two bags of laguna paper clay and 4 pints of different coyote glazes to try out. After placing my order I immediately got an automated reply from the big ceramic store that some of the items were out of stock, "sorry the inventory moves so quickly sometime we are out of some items" or something to that effect. I'm bummed, but the stuff is already ordered an I do want it. A week to 10 days later part of the order 2 bags of clay and 2 of the glazes show up (I paid $80. In shipping) a week later I call the store and get no answer so I leave a message, another week passes and 1 more pint shows up at my door. I call again and this time I get a person on the phone, I tell this clark I'm interested in buying some glaze and want to know if they have in stock the glazes I need, she tells me there is no way they can check to see if an item is in stock as the inventory is to large and moves to quickly. This isn't what I want to hear so I hang up without ordering anything additional. Checking google reviews seems I'm not alone, there are many complaints about "The Big Ceramic Store" so buyer beware. I placed an order with another store located in North Carolina, great customer service... I'd mentioned to the n.carolina dealer that I'd recently had some difficulty and they knew immediately who I was talking about, even commenting the reputation of that store (without mentioning the name, wink, wink, nod, nod, say no more) was terable. I called again today to see is they could just ship me something else they can find in inventory, but they aren't answering the phone and the voice mail box is full and won't accept anymore messages...Big Ceramic Dissapointment.

    No shelves

    I can’t imagine trying to transport work just thrown on the wheel in my car and in all the years I’ve worked in clay never a studio or classroom has been without a place to accomodate some work in progress, at the very least one project at a time if space is really limited. I did belong to one studio that for a time was out of shelves to store clay bags and odd tools and any work that would fit for extended time, perhaps that’s the case and there is a misunderstanding. Like liambesaw said I’d ask whoever is in charge or another member what space is available.

    Re - glazing a fired peice.

    I’ve had good result with a refire most of the time. lots of good suggestions and another trick that will make the fresh glaze stick better is put the piece in the microwave oven for a minute then try and keep fresh fingerprints off. Helps to stop the fresh liquid glaze from crawling on application and the warm ceramic fresh from the microwave helps to get a thicker application of glaze. Another re glaze technique is chose a second layer that is a lower temperature, allowing the layers to stack instead of flowing together keeping in mind the intended use of the ceramic item. On multiple firing at lower subsequent cones puts less stress on the clay body than firing up to full vitrification repeatedly it going to depend on the desired final outcome. One more thing be patient once the wet glaze is on the pot sometimes forcing it to dry to quickly will make the new un-fired glaze crack and peel as it dries if this starts to happen put the piece in a cool shaded area to dry more slowly.
  11. Shawn, watching you throw your technique is actually pretty good a couple of small suggestions, a little downward pressure on the rim as you open helps to seal the outside of the ring to the bat and helps to maintain center, staying perfectly on center at all time is absolute key to throwing well and maximizing the available clay. Hulk is spot on, work on timing you are releasing hold on the clay a bit to fast, take some time at the end of every action to allow the clay time to completely adjust to the last move will cure much of the wobble that holds you back latter in the throwing process. keep up the good work, you are doing exceptionally well for your time on the wheel. clark

    New Potter

    Take classes, you will learn something new from every teacher you have, this book was one I found helpful many years ago when I was learning to throw, “Pottery on the Wheel” by Elisabeth S. woody I did see the book for under $5 on line and internet videos were something not available when I was a young potter. I made a throwing video back in the 1970’s it was a grant funded project I was asked to do with one of the professors, probably good for everyone I don’t think it ever made the transition to digital. good luck

    Irregular shape pot

    Hard to say exactly how, he probably uses a combination of techniques depending on the piece. If it were me and I was making only one or two carving would work (taking away), if I were making more than a couple, or if they were large l would use clay slabs in a form assembled on/in a form and do alterations. Friend of mine when I was working out of a studio in Berkley, Ca. Was building giant planters for commercial buildings these were angular pieces 3’x4’x3’ he would pull them from the wood supports and beat them with metal chains and other stuff to give them texture. I might also try using a multi part plaster press/cast mold and then hand alterations if I wanted to do large production.
  14. It depends on how much clay I am throwing, I might just use a finger tip if only a small amount of clay is involved and on very large forms I might push down with the palm of my left hand really forcing the clay to open up. I think the one thing that remains constant and is the key point is I always open just slightly off center usually to the right and if I remain steady the hole will open just slightly larger than my finger(s) and I find it easy to stay centered with the pressure of the spinning clay at a steady pace from only one direction. The problem with opening by pushing directly down in the exact center is the spinning clay tends to push your fingers unpredictably and you can get a bit of a wobble as the pressure on your finger changes with the spinning clay. Next I’ll squeeze the clay between the fingers and thumb of my left hand while pushing down on the to of the donut with my fight hand and slowly pull towards me feeling the clay and giving it time to respond. I maintain bottom thickness with my left index finger as I open and stop pulling when I have the desired inside diameter established. Squeezing the clay at the bottom of the donut after opening will help move some of the clay up and help start your first pull.
  15. Times were very different when I was in college back in the 1970’s the whole getting sued thing wasn’t so out of control. I lived very near my local community college and the ceramics professor gave me a key to the studio so I could help fire the kilns, two big old alpines.

    I made a press mold that gets me the body and some texture to speed up fabrication they are also made hollow the fins and other detail I add, size is around 3”s long.

    Thanks Babs, I’m making some different thrown pieces and these each will be a fish lid finial and on the body of the pot I’ll write/stamp as part of the decoration “yi tiao yu” Chinese for “one small fish”
