  1. This is really helpful thanks. They're trimming super well and even. The way you only tape/cover the rim and leave the rest exposed is interesting I never thought of that.
  2. Thanks everyone it seems my issue is likely that I'm not transferring the plate properly from the original bat to the wheel for trimming. I wasn't doing the flip technique mentioned I was just lifting it off the bat manually which may have been why I had the warping. I'm going to have to give it another go and hope I yield better results with your advice!
  3. Ok yeah makes sense it does keep it's shape after trimming. I'm not new to pottery but apparently new to making dinnerware plates haha
  4. That's great advice thank you. So after trimming to get it right side up again do you flip it again using a bat?
  5. I basically did the same, I let them get leatherhard on the bat then only removed them for trimming.
  6. Good point that's a possibility I have seen a ton of videos where people flip the piece onto a clean bat. I didnt do that, I just lifted them off the bat which could have caused this problem. I was able to flatten them back again since they're leatherhard but because of the clay memory I feel like when I fire them they'll resort back to bring warped. Sigh.
  7. I'm throwing them on the bat as well. I only I'm throwing them on the bat as well. I only move them off the bat when ready to trim.
  8. So I'm on the quest to make proper dinnerware plates. I first tried handbuilding them using the G R Pottery forms and when I fired them almost all warped in firing. I recently made some nice thrown plates and just finished trimming them. I go to check on them today and every one is already warping. They're all ovaling or what I call lemon-ing out. They're basically at the middle of leatherhard now. I had them about 80% wrapped last night and intending on drying them to leatherhard slow and steady. I'm using cone 6 Standard 710 brown clay and compressed them very diligently with my rib when throwing them. I'm far from a plate expert but have made others using various clay bodies and never had this issue. Do you think it could be this 710 clay? I appreciate any help you can provide!
  9. So I ordered some new kiln shelves and thought I had kiln wash. Turns out I think I brought it to work and left it there. I wanted to fire tonight or tomorrow. Does anyone have any DIY kiln wash substitutes or recipes I could use? I don't mix my own glazes anymore but I do have potash feldspar and frit in my cabinet if that can help. Thank you, ~Dianba
  10. Ow that's good to know - I bought those same exact Minnesota Stamping Pads and that's what I intend to use.
  11. Ok thanks for the advice. Some of my pieces such as my slab built plates don't have a foot on them so clear glazing over the underglazed stamp could be tough.
  12. Hi Everyone so I have a stamp with my new logo on it and I want to stamp the logo onto the bases of my tableware pieces using underglaze. My intent is not to have the stamp make an impression in the clay, rather a surface decoration. So here's my question...if I stamp the pieces after the bisque with the underglaze do you think it'll hold up for wear and tear? I never use underglazes on bisqued wares but I know they technically can be used. The pieces are currently bone dry and I may not want to risk stamping the bases now with underglaze in their fragile stage. Thanks!
  13. Hi I also live on Long Island in and I get my clay from Ceramic Supply in Lodi, NJ. They do truck deliveries once a week to LI if you order a minimum of I believe $200 worth of clay with small or no delivery fee. If you want less clay you can order ahead and pick it up at their warehouse in Lodi which is actually also an amazing retail store. Maybe just call to be sure they're operating as usual given the pandemic. I did get a recent delivery from them but it was a month ago. Good luck! ttps://ceramic-supply-inc.myshopify.com/
  14. Hi everyone, so quarantine has allowed me to finally get into the studio and make a dinnerware set for my home. I'm making great progress but could use some suggestions with firing the large dinner plates. I've made eight 11" handbuilt dinner plates formed from a drape mold. I was very diligent about constructing, draping, and drying the plates. I've gotten them to bone-dry successfully without warping and I'm about to bisque fire next week. So here are my questions: Any tips to successfully bisque-fire these plates so they don't warp or have issues in the bisque? Any suggestions on how they should be places on the shelves? I'm using standard's 710 deep brown clay cone 5 clay and I have a small select fire Skutt kiln. I'm not new to pottery, I've been in the pottery world for 20 years but honestly have only made a plate here or there. They're typically not my favorite thing to construct, so I welcome any advice. Thank you, hope everyone is staying safe! ~Dianna
