    Benzine reacted to liambesaw in New year's rush?   
    Anyone else getting a lot of orders after the new year?  
    I'm so busy with orders my head is spinning!  I have open orders for tableware from 12 people in the last few weeks.  Mugs for teachers, tableware sets from coworkers, bowls from neighbors, people from Instagram of all places, I mean it's crazy!  I thought the holidays was busy, what's going on?  
    I'm thinking people are anticipating tax refunds or something?  Never had them line up before it's great!

    Benzine reacted to neilestrick in Covered jars   
    Depending on the type of pot and lid, you run the risk of either the pot or the lid warping slightly during the glaze firing if they are fired separately. If they fit well before firing, it will only take a tiny bit of movement to mess up the fit. There are ways of dealing with runny glazes via application, or you can choose a type of lid where it's not really an issue. The glaze combination on the pot below is incredibly fluid, but because only a small amount is on the underside of the lid, and it's not vertical there, it won't run into the jar. The other nice thing about this type of lid is that the unglazed portion doesn't show when the lid is on.

    Benzine reacted to Pres in Griffin Grip - I like it, but what a mess it makes!   
    As Ben mentioned in his post, I did use a large round plastic bowl cut in half to catch trimmings from the griffin grip. However, I few years ago we renovated the kitchen, and I repurposed one of the counter tops by adding sides to it and cutting a slot for the wheel shaft so that I could slide it on to the wheel with the regular splash pan off. Then I added pieces of wood on either side underneath so that they would grip the sides of the CXC holding this new trimming area in place. I also added a magnetic tool rack on the right inside. This way I can stand it up when not in use resting on on the open end at the end of the CXC acting as a table for my tool rack (silver ware drying/storage tray). Now I don't have to store the extra splash pan anywhere, and don't have piles of trimmings on the floor.
    As Ben said also, the GG is a great tool for assembly. I use it to trim and assemble chalice and patens. First trimming the thrown stems, using a rig I made up using plumbing parts, then I trim the chalice bowls and mix and match stems to bowls and assemble while on the wheel, using the wheel to compress the joins, carve an inset in the bowl to match the stem and smooth the join more with a metal or wooden rib.
    You can see much of this on my blog.
    best,

    Benzine got a reaction from Pres in Old crunchy glaze   
    The great thing about glazes is, that like clay, until they are fired, they can continuously be reused/ recycled.
    I use a stick blender to mix slip and glazes, because you don't have to move the material you are mixing to a different container, which is handy.  
    If the glaze is still heavily settling to the bottom, it may need to be tweaked a bit, by adding some bentonite and/ or epsom salt, to help better suspend it.

    Benzine reacted to neilestrick in Old Shimpo (used) slow at 5lbs.   
    It could be that the drive wheel is slipping on the metal cone. That wheel is rubber, and can get hard over time and lose grip. It's also possible that something else is loose in there and slipping under the load. I'd first open it up and see if anything is obviously loose. I think @Pres had found a source for the drive wheels a while back.

    There's no control board in it, just good solid parts. They don't run especially smooth or quiet compared to modern wheels, but they keep on truckin'.

    Not without stilting it.  Even then I don't suggest it.  You can order some progressively finer diamond disks from somewhere like Amazon and just polish the bottoms with those.  It makes a smooth shiny surface.

    Thank you all for your input...I'll take each of your suggestions and put the vase through the ringer and see how it holds up, but first I'll give the outside a couple of coats of clear acrylic to protect it as I usually do.

    Just received my first liter of Liquid Glaze and used it on the inside of one of my Horsehair Raku pots following the mfg instructions and it worked! The inside of the pot is definitely hydrophobic...Filled it with water and let it stand for 4 hours with no sign of seepage. I'll leave the water in the pot for a couple of days to see if there are any adverse reactions. If none, then I think I'll have a new line of watertight Raku pots that can be used as vases...Hot Damn!

    Benzine reacted to Min in Raku second firing?   
    They say as much on their own website, not even recommending using it on earthenware for functional work. " Note that if the surface you seal is not completely solid (lowfired/low bisque) the sealer will still fuse with the surface & be waterproof, but only for as long as the surface remains intact, therefore heavy scraping of cutlery on unstable bisque fired plates is not recommended. Earthernware clay bodies fired to their most vitrified temperatures (terracotta etc.) can be sealed with much success, but will remain more suceptible to chips & damage than high fired stoneware or porcelain, as the claybody itself is not suitable for restaurant quality plates, cracking easily & requiring gentle washing to prolong the life of the piece. This is the nature of the clay body, & cannot be changed by sealing the surface only. While your work will be waterproof & stain resistant, it will remain brittle & easily scratched if low fired".

    There are way too many warnings about what that product cannot do with low fire, porous surfaces. It specifically says that it cannot make a toxic glaze food safe. It says that prolonged contact with some foods may mar the surface. It says it will not make your clay body any more durable and less resistant to scratching, that it will still mark from cutlery and chip easily. If those were issues with a specific glaze we would not use it on functional work, especially plates. That product is simply a sealer, it should not be used in place of a good glaze, especially on plates. Raku should never be used for dishes, even with a sealer IMO. As soon as there's a scratch in the sealer, it's no longer sealed up. You're not only opening yourself up to an unhappy customer down the line after using the plates for a while, you're opening yourself up to liability.

    THAT'S DISGUSTING!  Urine should not be used in glaze, but instead, just swished around in the mouth, as a teeth whitener like nature intended!
     
    Seriously though, my High School Art Teacher told us stories of he, or at least people he knew in College, who would urinate on their Raku pots, after pulling them out.  
    Did this actually happen?  Who knows?  Myy Teacher had stories for days, and at the very least, they were entertaining.

    It's not at all uncommon for single zone kilns to fire unevenly. If find a section is firing too hot, then pack that section tighter with pots so there's more mass there. If you have a cold area, pack that section lighter so there's less mass.

    Sarah:
    I looked up your Super White: which is Grolleg kaolin based, but also uses ball clay as a plasticizer. Grolleg is about as clean as clay gets and fires high white; however using ball clay introduces contaminants such as magnesium, titanium, and iron. In this case it is not iron, but rather magnesium reacting with titanium. In addition, this body has higher flux levels which also play a role in creating the brown toasty color. Leave the plug out until 1100C, and do not allow pieces to touch each other, nor should you stack them. See test bar 4 below: which is high titanium, flux, with lower iron and magnesium.

    Please pardon my lack of fluff here, but I feel that modern society has perverted the idea of kintsugi to be what it was never intended to be. It was never intended to be a way to repair pots that were made to sell, or to cover mistakes. . It was a way to repair long cherished pots.

    So if it's part of a process that's normally done post firing then it's not a repair, but....
    Applying a urethane or wax post firing is, even though it's part of the process?
    A repair means that something happened that wasn't intended and needed to be fix, whereas applying a urethane or wax is part of the process. Is waxing your car a repair? No, it's meant to protect the paint so it lasts longer. Touching up a chip in the paint would be a repair.

    I thought we were talking about raku, not your pots? The color in a raku copper glaze probably won't last any longer than a car's finish, so I think it is a good analogy. You wax them both to prolong the life of the finish. Both can oxidize over time.
    We don't all think of it that way. Not all ceramic work requires durability or longevity. I personally strive for that in my work, but for a lot of people their work does not require it, nor do they strive for it, and I don't think it makes it any less valid.
