  1. Highwater clay users

    (thixotropic) this happened to some laguna clays like B-mix out west here some years ago. Laguna had changed water sources and it really did a number on some clays.
  2. Keep your seconds as Mea says for other venues not shows. I used to save mine for home sales but gave up home sales after 19 years of them. Now I take them to one local show that is a lot of students whole look for seconds. I now save them for that deal.
  3. I often make square bowls bowls. After trimming and putting a foot on them I rewet them and paddle them square.Just another way to get square pots .
  4. The issue with commercial glazes his you do not know whats in them or how to fix them. I can add that your body cone 6 to then 10 is a big issue but you already know this. The only other point is Laguna makes glazes with the cheapest materials they have in glazes -meaning silica (most likely 200 mesh) etc. I know this as they make glaze for me in 1 ton lots, but I specify the materials vs let them use the cheapest. On the plus side they usually are the cheapest suppler around. One last factoid they have a New owner as John Brooks sold it this year.
  5. anyone ever tried the vertical slab rollers?

    I have often wondered about this as most slab rollers come out flat and thats the way I use them so I do not have to move the slab much (distort) In a vertical I think you would have then lay it flat (distort it more?) not sure on this point maybe Doc can clear this up. The best thing in theory is gravity would make it want to self feed.
  6. I usually just greet them being friendly if its slow-the pottery sells itself.
  7. microwave proof?

    Another issue for microwave is iron. If your clay body contains iron that will heat up the pot and if its a rich iron bearing clay it can damage the microwave . The usual effect its a very hot pot with typical stone wares bodies.My Porcelain clay body since its iron free microwaves well.
  8. name this glaze?

    I think you got it Pres since most likely its not a mug intact after all those years.
  9. name this glaze?

    Looks like a cone 10 reduction fired glaze on a stoneware iron spot body-very popular in the 70's . The satin Matt is the hard part. maybe a waxy white ?mine was called Billy Joes butter white and looked very close to this if fired in the right conditions (reduction) on the right clay and glazed the right thickness in application. Maybe from Laguna in their cone 10 glazes in dry powdered form. Always mixed my own.
  10. I also would keep your price at even numbers . You can add tax to that price during the sale. I have done this for over 40 years. People these days really distain change.I actually round up or down often to the nearest quarter most of the time when giving change. The exception to this is grocery store pricing where they always end the price in 9.
  11. What are cone temperatures

    Cones measure time and temperature (also called heatwork) Since they are in kiln along with your pots they are the most accurate . Controllers recreate this electronically . These work really well but the downside is they can break but the risk is low as Neil says he has 2500 firings without cones. They use thermocouples to get the info and these can wear out and can give false readings. Type S thermocouple are the most accurate and cost the most and last longer . Most kilns use type K thermocouples. I consider thermocouples to be the weak link. In my temperature range and atmosphere (above cone 10 in gas reduction) these thermocouples are less accurate. I use platinum thermocouples which cost the most. I suggest using some cones spread around your kiln and learn whats going on in all those locations before giving them up. Just as Mea says in above post.
  12. fixed it-they are now keeping those animals out of store
  13. Dipping Pots into glaze

    Some pro tips to glazing mugs are to blow the glaze with your mouth right after dipping or pouring at bottom of handle to they get thinner and do not pool (run ) at this trouble spot .
  14. I reached out about a year and half ago to get my work in a natural foods market that was going to open.They gave me an end cap at just the right height. As I found myself wanting to do less road art shows and this seemed like a good idea. That market has worked out very well for mug sales and sponge holders. Today I find myself in 3 markets.This display went up yesterday in my home town co-op.My member is #12 from the 70's so I have some history with these stores. I'm in both of their stores now . One started two weeks ago. I wanted to try some other forms as well as mugs.I make a weekly drop off to all stores (one store has a courier to their other store)so its only one drop for two stores.These are straight wholesale deals. I sent the final price and they took 35% of that. The thing with all grocery stores is all price points end with 9. No matter if its 10.99 or 24.49 its always a 9. On Thursdays I make my rounds like bread delivery truck only with pots. My distant town store shoot me a photo of the display with a whats needed list so I can have it boxed and invoiced for the courier to take to other towns store. I have experimented with pricing at my first store and found the sweet spot for steady sales.I have always offered to buy back any work and this has yet to happen but I know it will in the future when some forms will just be to slow. I then will just take them off the next bill of goods I take them the next week. The store cannot loose. This has been a NEW business for me and since I have been in this pottery business since time began its feels nice and fresh . If you can make a quality line of work and keep enough back stock ready at all times and are dependable this can work out very well in terms of steady dollars The one store sold 19 mugs last week so you can see its adds up fast. This is shift from road dogging it 2000 miles to Arizona art show to a steady stream of weekly or every other week drop offs. I'm driving the pottery van around once a week now and its been good. I thought I had saturated my local markets here but now I really have as i'm inside them now as well as the outside shops.Now lets see how long until i go nuts baking all this bread. The photo is top shelve right sponge holders and soap dishes Main Shelve is cereal bowls, 5 sizes of mugs-french butterfishes candle holders and salt cellars-thanks to Min.
  15. when I use wadding its always mixed up in a sealed plastic gallon bag. It firm but moldable. never wet, I use it in slat kiln and to retire salt pots in reduction kiln. I use brown shelve pieces in all dimensions to stack the shelves. I have a bunch of small 3/16 advancer pieces and some 1/2 inch and 3/4 inch mullet and carbide pieces . They are all washed and do not stick to posts. I have called them nerds for 4.5 decades and no matter what you call them they are nerds to me. I never use wadding in my weekly reduction or electric firings-I could but its no need as the stacks are solid .
