    spectrum underglazes

    I use underglaze quite often. I mostly use Amaco and Duncan, but the others seem to be really good as well. Yes, I blend my underglazes just like you would with watercolors. I have mixed larger amounts of two colors together in order to get just the right shade of green/red/blue/etc. Usually I just use smaller amounts in a little palette and blend or even water down if I am wanting more of a water color effect. If you have watercolor experience, you will love what you can do with underglaze. Roberta

    Calcined Zinc Oxide

    I used up my supply of zinc oxide. The supply house is 200 miles from me, so when my cousin was coming over my way he asked if I needed something from the supply house. I called and ordered some zinc oxide. When he delivered it to me the container says Calcined Zinc Ox. I know what it means to calcine, I was just wondering if it will change the recipes I use? And the zinc ox I used up originally was several years old, so I do not know if it was calcined or not. What is the general thought amongst you glaze/chemistry/ chemical gurus? Roberta

    Calcined Zinc Oxide

    Yes, thank you for the clarification, Mag. Mud. It was zinc oxide I was asking about. It's almost as dry as Death Valley here where I live. And my containers are closed. Thank you for the information. I really appreciate all you all. I am not kidding. This forum is where I go for specific information. Thanks.

    Looking for a purple cone 5-6 glaze

    I have used a couple of the purples from John Britt's book. Pikes Peak purple, and Ashley's purple. They are both matte. Is that what you are looking for?

    slow leaking pots

    I started in a community studio. Many of my pots would leak as well. And sometimes grow mold. After researching the matter, I found that the clay was not vitrified. The clay bodies being used were for a higher cone that what was being fired. I was not able to address this with the person in charge, so once I had my own kiln, clay, glazes, I bought clay that was appropriate for my firing temps. And made certain my kiln was firing to the proper temp. Perhaps you could ask the teacher if she uses cone packs in each load? And read up on vitrification. See if you think it addresses your problem. Roberta

    I don't believe I have ever sold something from Instagram. But I don't use it for that purpose. I just use it to stay in touch with potter friends. And to make more potter friends. It's nice to have the connection. And I certainly do not have 30K followers. Maybe 100 or something. No clue. but You can get out of it what you want. And I will use IG to promote local events. I have not found it to be as snarky as FB. A little kinder. But maybe that's because I am interested in potters and pottery!

    Hardening of glaze

    The only glazes I have had crystallize are ones that have lithium in them. But that is after they have been in the bucket for awhile. Not immediately. I hope one of the glaze gurus can help you. Do you have the recipe available??
  8. I throw in the house, in a small room, where all I need is a small radiant heater for a short time. My kiln and glazes are in the unheated shop. But it is very well insulated, and I can close off my side of the shop with doors and again, a small heater takes care of the comfort level. The first winter I had the shop I was constantly running out there to check the temp. Even with 30 below or more, it never freezes in there. So I don't run a heater unless I am out there. The rest of the time, the kiln keeps things warm. I feel very fortunate!

    New Potter

    Definitely start with classes. Find a way to have time to practice on your own. While you are taking classes, do some reading, watch some videos, ask some questions. You may find you do not like wheel work as much as hand building, or vice versa. I started at 52 and never looked back. 12 years later I still make it a priority to take classes or workshops. It's a great way to build skills and connect with others. I would advise you to hold off on purchasing equipment until you have had some experience with clay. The classes will help you define exactly what it is you like and don't like about clay. Best of luck to you! Roberta

    How to fix warped plates

    Are they warping while drying? Or do you notice the warping after the bisque firing?
  16. I have done that as well, just get some sort of mat under the Tyvek and an exacto knife and make your own stencils. Tyvek works great on slabs, paper works better on dry leather hard pots, (dip the paper in water, sponge or rib it on the pot, apply underglaze, let dry a bit, then peel the paper off. ) You can also cut your own stencils out of paper, using an exacto knife, a couple of thicknesses of paper and a mat.
  17. I have used rubber stamps on bisque ware quite a bit. As was mentioned before, it's better on a flat surface but you can 'rock' the stamp on a curve and still get a good impression. I was taught to make my own stamp pads with a sponge, a brush, and underglaze. I use sponges I get from the hardware store for grouting, cut them up to the size I need, brush underglaze on the sponge and then tap tap tap your rubber stamp on the glazed sponge. It works well, does not bleed, and is permanent. You could slide the whole sponge into a zip lock bag and it would stay moist. I have carved stamps out of clay and bisque fired them and those work well, I have a manufactured acrylic stamp that I use for a local business, there are lots of ways to achieve your end goal! Good luck. Roberta

    Selling Internationally - Import Taxes

    Joseph, just to be clear in my own head, the mug was one price, the shipping was one price, then the customer paid an additional 25 Euro for duty fees?

    In the search bar at the top, type in those subjects. There is a LOT of information on this forum concerning stains, engobes, Underglaze, etc. Once you have read through that, you will have many more questions, that can help to clarify! Roberta

    Terri’s Earthy Rusty Yarn bowl

    Absolutely beautiful!!!
  22. Believe it or not, but I have also tried most of those clays over the last 10 years. For a variety of reasons. At this moment I am using Laguna #16 and Laguna WC429. They are both easy to work with in a number of techniques and most important to me, work well with my glazes and make sturdy functional ware. But I do not believe they would work for you with your criteria. You did not mention Laguna Half and Half WC402. It has some grog to make it stable but not too rough. Before I read your list I was going to suggest Aardvark's Artic White. It was stable and easy to work with as was Texas White. I do know that they use Laguna Dover White at our local community college. Laguna WC398 is not on your list. I haven't tried it but it sounds promising for you. Would you have space in your classroom for your students to change their shoes or wear aprons? Clay is messy and that does seem to go along with the process. There are a number of teachers on this forum that may have better advice for you in that respect. Roberta
  23. Mea said it best. Your first show will be your test. You will have things left from that show that you can stock in the 2nd show. I usually have work that is bisque but not glazed in between shows, so I can have a few glaze loads in that two week time. And simply take as much as you possibly can so that you see what appeals to your customers. Make certain to engage in conversation about your work, customers will give you insight as well. Have a great time!! Roberta
