    Roberta12 reacted to LeeU in QotW: Are you planning to add any new glaze colors to your palette of colors?   
    My challenge is to be more attentive to constructing an intentional palette in the first place. I gravitate to favorite combos and then sometimes just get spontaneous with whatever strikes my fancy at the moment. I make plans to develop a couple of palette schemes, and cut out glaze swatches from catalogues or print them out from web sites and tack them up on my inspiration board...and usually never look at them again.

    yes, more testing will happen.  It was such an easy project.  I used paper stencils on bone dry clay.  I have done that many times, but I usually thin my ug a bit.  And this surface issue didn't happen until glaze firing.  After bisque it was smooth.  I also discovered in that load that the 7 cone was down!  I haven't put cone packs in for awhile because I was out.  I will start doing that with more frequency.

    Well, Primal came out looking less exciting than I hoped so I am going for a refire. Not Broken broke a little bit again and did not get the super colorful treatment I'd planned---I decided to keep it simple. Here is the finished wall piece.

    @tzylawy, I'm copying the image you posted in the gallery into this thread so it's easier to find.
    Definitely wouldn't fire this as is. Was the glaze frozen at some point or is it really old? Also did you really stir it up before using? Did your brush drag as you were applying the glaze? Reason I'm asking is it looks like the gums that are typically used in brushing glazes are no longer effective. Is that the same glaze on the inside of the pot?
    I'ld scrape off as much glaze as you can (wear a mask), dump it back into the jar and scrub the outside of the pot. I'ld then add a little bit of gum solution and enough water to make a good brushing consistency and try it again on a test tile. If it works on the test tile then reglaze your pot. (it's easy to make your own gum solution if you don't want to buy it)

    I had the same bone removed as you in left thumb ,the lower bone, last Jan. 19th this year.
    I rehabed it and am now only experiencing a weaker wrist and some minor pains now and then
    The unusual  deal is my wife had the same bone removed on May 18th on same hand-same surgeon
    I asked for a two for one deal but it was no go.
    That surgeon was trained 20 years ago my my  surgeon who did  my PRC 11 years ago on right wrist. She is now at Yale and this one is in Northern Bay Area (SF)
    This clay work has taken its toll on my hands for sure.After 11 years now with my peter pugger I wish I had one 30 years ago.
    Apple juicing this weekend for us now as well as rototilling the garden with a winter cover crop before i leave for big show trip.
    Always something around here to do.

    Roberta12 reacted to Mark C. in The last show in the desert   
    Been doing a show in a small town in the desert east of Las Vegas for about 30 years now. It was cancelled last year and I let my fees roll forward and its coming up in about 3 weeks.
    Last one in 2019 was best ever for that show. Its the most open show in a breezy loction in a grassy park under a huge shade tree. No canopy  used as it not needed and usually to windy. I just walk away from booth when done  every night as the town is sleepy and no issues ever with theft in 30 years. I am the only one who does this I should add. One whole day to set up (friday)  and van is 6 feet from booth and stays there for whole show. show is a early am start usually sales start by 8 am and is dead at 5 pm.Show is easy and I do it solo usually.
    show is a mix of fine art and real crap not made by anyone locally (buy and sell) Its in 3 parks and I am not in the fine art park. They always wanted me up there but you need to pack your stuff in and no shade tree so I always have stayed under the shade in park with lots of buy and sell and my stuff really jumps out next to junk.People love the shade when its hot and it usally is.
    I think this will be the last show for me there. I never say never but will fly a sign saying I;m done most likely.The show is just a bit to far as it just over 1,000 mile each way. I no longer need shows outside my area as well. Its part of my slow down plan.
    Most of my fellow artists have quit the show  by now and I'm one of the last hold outs-its been a very good show for me and I always fit in another wholesale drop off after show  on this trip in Santa Barbara and I get to vistit my sister there as well. I always fit a medical appointment in SF on way home as well. 8 days on the road this time around. 
    This years whole sale order is huge at a small gallery that only sells pottery in Harmony Ca.I will meet the owner after selling to him for over 10 years without meeting him. We have a stop on the road to fill his forester on the day we head north from SB to SF. in a parking lot. I will have about 20 banana boxes stuffed for him. He always cuts me a check the second he gets the pots -best business man/woman I have ever dealt with. He is also a potter so he knows the drill. His shop carries lost of potters work from all over the USA.Never been there myself-its in a town with population of 10. On the main US 1 highway  popular with tourist route up to big sur and Hearst Castle
    I have loved mixing whole sale order drops with shows  over the years as you really get home with a  extra large payday. This will be the last one of these for me. Next year I'll take it south and not do the show but still visit my sister and my nephews.
    Next year my plan is only one out of area show and one local show and my own xmas sale as usual.I'm slowing it down to local sales and even that is going to slow down as I stop supplying a few outlets (I have 9 locally this year)

    If it helps we found color and thickness to be a primary cause. In our case we needed a tested glaze that worked pretty much no matter how the artist wanted to paint it else be accused of stifling creativity!  Hence the glaze solution. I think I only increased the boron a few points, so .15 to .19ish. Marcias matte is on glazy if you want to double check what it was brought up to. Anyway, IF this is your issue folks have been successful at adding a tiny amount of boron fritt or GB to their underglaze colors prone to this. Tiny amount seems to be key else the glaze chem locally is a mystery. Hope that helps.
    As usual tesssssst.

    If you make your own glaze,  you need to make up test samples of some different formulas.   Purchased glaze cannot be easily change,  trying a different brand might help.   It is probably the clay,  if you are firing  C5/6  glazes  you need a clay that is  C5/6  not one that can fire to  7,8,9,10.    Denice

    I'd put money saved on gas for a distance I probably would get tired of real quick into hours I could book nearby at my convenience--getting out and doing something is better than staying in and doing nothing. I make decent small items that I can peddle locally and that helps me at lease break even. Personally I can't stand unanswered questions-I'd rather get a "sorry, no time to answer, try someone/somewhere else" than dead silence.  There's a lot of inadequate-poor-just plain wrong-info about claywork on the Internet /FB, as well as "taught" in some community studios, but I can trust the recommendations found here, especially for online resources like specific workshops/videos. For me, since I am not into production or making money, my best approach is to keep it simple and just have some fun while I explore & learn whatever it is I'm focusing on.

    @Roberta12  Thanks for the tips!  I've always liked Amaco's colors much more than Mayco's.  I was using Amaco when I started having glaze problems and called Amaco.  They couldn't help and my supplier suggested Mayco.  He loves it, probably for considerations other than the color! 
    My studio is inside my home, in an extra bedroom so I can't spray glaze.  Since I brush it, I take a lot of time to smooth over it with my fingers, eliminating pinholes.  I've seen a nice demo on bisque, with wax and glazes.  Might try that.  if I try once-firing, i will check with @oldlady, thanks!  
    Thanks, Roberta, I appreciate your help!

    Re the debate of a refractory underglaze or not it would be fairly simple to test this theory without altering glaze recipes. Since we know adding flux will make things less refractory and adding alumina the opposite, using this logic I'ld run 2 parallel tests, one adding flux, Gerstley Borate should be a good choice, and the other adding calcined kaolin.  Say roughly 1 Tablespoon liquid underglaze + 3/4 teaspoon of Gerstley Borate or calcined kaolin plus enough additional water to make them brushable. Apply to both a vertical and horizontal surface with the same number of coats and fire them both the same and see what comes out of the kiln.

    Sue McLeod is doing an underglaze research group. It might be good for you to check out what she's doing and add your input. Go to  Sue McLeod Ceramics and find "Troubleshooting Commercial Underglazes" . She has charts you can fill in to track your testing and then share with her to compile the results. I believe she has a facebook group as well where you can discuss these issues. 
    I apply underglazes to bone dry work. I also mix up my own underglaze like or wash like formulas with mason stains and flux, sometimes adding other things as needed such as a bit of my clay body slip, CMC gum, or white underglaze. I notice that the mason stains act differently from one another too just like the commercial underglazes do.  I fire to cone 5. I experimented a bit with different fluxes mostly just to get the mason stain to stick to the surface of my work after bisque. I've used frit 3124, Gerstley Borate and Wollastonite as fluxes.  The ratio is about half flux and half stain, but do some experimenting if you add things like your clay body slip because it already contains some kind of flux. 
    It almost looks like the black is trying to pop itself off the clay but the glaze is sort of holding it on. I've had big flakes of underglaze come off after bisque, I think when it was applied too thickly all at once. It seems like  a good way to get it to adhere better to the clay is to use a more watered down first layer so it sinks into the clay instead of sitting on top of it.

    Roberta12 reacted to neilestrick in Underglaze pinholes and flaws - I don't understand why?   
    My thinking is that a thin wash of underglaze simply don't have enough material to affect the glaze melt, but the thicker areas are being taken into the glaze a bit and messing up the melt. That blend is not a good proportion of fluxes to get a smooth finish, as when a glaze bubbles before smoothing over. The underglaze, being more refractory than the glaze, is keeping the glaze from completing its melt. It bubbles but doesn't smooth over. By increasing the boron in the glaze it's allowing the glaze to finish. So yes, the underglaze is more refractory than the glaze, but the underglazes that have this issue are less refractory than underglazes that don't have the problem. Underglazes are not supposed to go into melt.
    That said, I have also seen this problem with glazes that are quite fluid, so I think it also has something to do with the glaze formula, not just the melt.

    Lovely that you found a solution that works for the potters in your studio but from reading the original post from @carolrossit sounds like she is using a commercial brushing glaze. I think we need to work within the parameters of the the op's usage insofar as commercial versus studio mixed glaze.  Like many things in ceramics there are times we can make things more complicated than they need to be.

    Roberta12 reacted to neilestrick in Ikea trying for handmade aesthetic   
    There's a big difference between an object being imperfect because of the forming process, and something that was made perfect and altered to be imperfect. One happens organically, one does not, and it's usually quite obvious, with no mystery as to how it was done. A slip cast bottle that was dented when it came out of the mold is clearly a slip cast bottle that was dented when it came out of the mold. It's an incredibly poor representation of the imperfections that occur when a piece is made by hand, and it's insulting to both the mold a maker and the potters who should be making those pots. If they want the imperfections of hand-formed pots, why not source hand-formed pots? They talk like they're being super creative and designing something new and crazy and exciting, but it's an aesthetic that is common in the ceramics community and has been for decades.

    Roberta12 reacted to Bill Kielb in Gold Luster firing questions and schedule, help!   
    I would suggest reading the article in the link below  start to finish, it addresses most of your questions. If after reading, you may have some new questions to post. Lusters need ventilation in application and during firing. Lusters fire around cone 018 so not very hot compared to your normal glaze firing. Lusters generally can be fired very quickly. The fired luster is influenced by the glaze it is fired on. Too thin an application will not end up shiny and gold. Too thick can drip. Much of this knowledge is obtained by experience so in the beginning maybe some test pieces before applying it to your best work.
    Here is a good article that is a nice overview IMO. https://ceramicartsnetwork.org/daily/pottery-making-techniques/ceramic-glazing-techniques/use-ceramic-luster-glaze/
