    Repairing Gas Kiln Arch Bricks

    I used them on the kilns i built at the university over 25 years. I liked them and adjusted the arch bricks when needed by tightening the threads on the rods with the springs. just one of those things you either use or don't. I like catenary arches but sprung arched are my favorite to build. Best wishes to you, Mark. Marcia

    Saggar and Raku Kiln Questions

    My new kiln shed houses four raku kilns and three electric kilns. I would not sagger fire in an electric kiln. I use some very caustic chemicals in saggars.This photos shows my tophat full of saggars. It is propane fired.

    Repairing Gas Kiln Arch Bricks

    this is not a Roman arch , but a sprung arch. Roman arches are semi circular running into the wall without a scew brick. A. P. Green handbook for designing arches helps you configure the rise per foot and the radius and what bricks are needed to construct the arch as well as which stew brick is needed. great little reference book. Car valve springs from junk yards do contract and expand. Used them for decades.Springs from a hardware store are not as resilient. That may be what mark is referring to. Marcia.

    Glazing a mortar and pestle

    if the whole thing is unglazed maybe use a little alumina in wax so the porcelain doesn't stick to the shelf. OR you could make a drip plate and put grog in it to support the pestle. Marcia

    Repairing Gas Kiln Arch Bricks

    I have used small bits of fiber soaked in ITC and stuffed into the cracks. Possibly a kiln patch material would also work. Question: is the kiln frame rigid? I always built arches using a threaded rod , large washers and car valve springs to allow the arch to breath (expansion and contraction) . Just curious if that could be the source of the problem. -no flexibility. Marcia

    Saggar and Raku Kiln Questions

    I have instructions for making raku kilns. https://www.marciaselsorstudio.com/raku--latex-resist---making-raku-kilns.ht I have a dvd from Acers/CAD regarding the potential firings of a raku kiln including: obvert, sagar and foil sagger firings. I enjoy the immediacy of the raku kilns and how many ways it can be used.https://ceramicartsnetwork.org/shop/raku-firing-with-marcia-selsor/ there are links on my website that have videos from this dvd.

    Red Mid-high fire range clay body

    here is my former teacher's (Bill Daley) clay body. He fired it at a brick yard conveyor kiln. Daley's is toasty golden, Linda's is rich and deeper color, and David's is the reddest. If you search the Ceramics monthly Archives for an article with Daley and Wright you could see examples of their pieces. Daley's and Linda's are more for hand building. Wright's can be thrown. I just noticed the above link has examples of Daley's clay body.

    Copper spot effect

    I have used very fine silicon carbide to achieve copper reds in ^10 oxidation without much spotting. If you want the copper spotting as on the first pot, you might try copper granules and fire the pot in a saggar for the glaze firing and include some charcoal briquets, Someone was discussing saggars in reduction on here in the past year or so.

    Age of dry materials

    I had a friend receive a large quantity of chemicals from a family of a deceased potter. It was going to cost the family about $10,000 to throw away the chemicals which would have to be tested for toxic disposal. You might explain that to the family when you make your offer. That is a lot of good chemicals some of which are extinct. I'd like to suggest to old potters out there to consider leaving your studio chemicals to someone so the family doesn't have to deal with disposal costs. There are lucky to find Roberta.
