  1. Ooooooohhhhhh........................................... feel your pain.........
  2. anan, you might be referring to my posts where i say i use the oven to warm glazed ware enough to have it accept glaze. i have been doing this for years and have only used the lowest temperature my oven can go, 170 degrees F. yes it may be in some way dangerous for ANY reason, but i cannot imagine what it would be. residue in the oven??? how would that happen? one hundred and seventy degrees is too hot to handle without a towel and if i only use pot holders, the pot is cool by the time i get it to the spray area. on hot days, putting pots in the sun will warm them enough to accept a new layer of glaze. they only need to get hot enough to make handling them uncomfortable. i have been told that "doing it for years is like walking on the edge of a knife and i might fall off at any moment." it is true that everyone has a different threshold of fear on different subjects. maybe i am just too stupid to be afraid.
  3. why not just add water to some of your basic clay to form a slip. then add color. there should be no adverse effects if you are using the same materials. earthenware clay and the same earthenware clay with color will give you a clay with the same properties as the original clay.
  4. if you are testing glazes, be sure to put something under the tests to catch the runoff if you have applied it thickly. and have a good kiln wash on your shelves.
  5. he is suggesting that you try the substitutes since you cannot get the originals and single fire. he is our clay expert and his advice is usually sound.
  6. read glazenerd's answer above.
  7. rew, it only takes a few minutes to keep the studio clean, or, at least cleaner than it is now. if you have a kitchen timer, set it for 15 minutes and begin washing down your horizontal surfaces putting things away as you get to them. bet you will be surprised when the timer goes off and you see how much you got done in such a short time. getting my kids to clean by color worked for them. pick up everything that is blue. now red, now yellow. that was when they had colorful toys. a timer works for me.
  8. one thing you might want to consider is where in the world you are going to be situated. yes, the world. will your booth open toward the east so the front of it will be exposed to very intense sunlight early in the day? if so, be careful not to burn customers who might pick up something dark and therefore extra hot. having an awning built into your tent is very helpful. if you can buy another one for the opposite side, do it. you might not be able to use both every time but when you can it is very good to have. will the wind be blowing and from what direction? are you going to be broiled by the afternoon sun by putting your chair in the left or the right back corner? look at the map that you are given to find your booth and make sure you know where N S E and W are in relation to the front of your tent. plan ahead is an old saying but it is a good one.
  9. i do not use a gas kiln at all. years ago, between 1975 and 1990, i did stack a round gas kiln for a friend with a broken arm. she said she had never seen anyone stack that way and it was the best firing she had done in years. wasn't to get me to do the next one, it was true that her work looked better. all i did was try to fit the odd shaped sculptures and other "normal" pots so air would flow around them. some shelves were whole and some half. some of the half shelves fit into the odd spaces left under the arms of the sculptures so nothing was stacked in a straight vertical line. they almost spiralled up inside the kiln. maybe that kind of stack allows the air and flames to penetrate differently enough to make it work.
  10. you could have someone with longer arms put a shelf into the bottom using posts under it. make sure you can then reach the new "bottom". i had to do this recently.
  11. yes, you are being unreasonably neurotic.
  12. see the other post. you really only need to post once.
  13. i assume you have contacted the distributor and the manufacturer. if so, call them on the telephone, talk to the store manager and if you need to, the person in charge of quality control at the factory. DO NOT SEND AN EMAIL! you will get no response unless you take an active role in talking to the person in charge who has the authority to correct this. emphasize the fact that you are not a rank beginner and therefore you know what you are talking about. offer to send a short video with sound so they can see what is happening.
  14. look at the side of the metal box on your kiln for all the information printed. LT-3K is the number of the kiln sitter, a shut-off device, nothing to do with the kind of kiln.
  15. are your current shelves going to be used in the new kiln? if so, check that finger width spacing. with gloves on, it is sometimes hard to get fingers under the shelves in my 3 inch brick kiln.
  16. $250 sounds really high for my part of the country. it is really old.
  17. maybe roof tiles for a planned dollhouse? my imagination is working overtime here.
  18. for something this specific, i would contact a museum in an area where pottery was made during those years and ask what they use for research.
  19. that is darling! i have things my kids made over 50 years ago. they still make me smile. be sure to keep them all, they grow up fast.
  20. thanks for the concern you have shown. yes, i have been having glazenerd examine the clay and compare it to pieces i had not fired from before the problem began. his results strongly suggest the ballclay ingredient is tainted with smectite. it is possible the mine it comes from just ran into the stuff. i waited for 2 years to see if it gets better but it has not. i wrote to highwater and explained his result and have had no answer for 20 days. each time i try someone's new little loafers it is the same way. cannot cut it cleanly from the bag, it sticks to the cut surface and lifting it results in deep fingeremarks and a tiny amount removed. i still have several boxes and will use it for throwing. but my income depends on the slabwork. if the things i used to make in one afternoon now take 3 days, i cannot continue to use it. thanks, joseph for the affirmative on 365. i know someone who uses it but she is out of the country for another week, thought i would ask here for second, third, etc opinions. you use such lovely glazes that i think it might be just what i want. a transparent green is paramount. i will look for laguna, john, thank you.
  21. thank you both for the suggestions. in looking at Standard's clays i find there is a cone 6 grolleg porcelain, 365. anybody use it? anybody not like it? i have over 500 glaze tests for my little loafers and at my age, i really do not want to do much more testing for a new clay. 181 has a range of firing temps and we have discussed that before. if i am going to try several to see which fits my needs best, i need some more suggestions. it is a long way to the supplier and i would like to have several white cone 6 clay names or numbers before i go. so far only 48 members have seen my original post, not a very wide sample.
  22. this sounds like one of the strange chinese kilns that have hit the market recently. it is obvious that the person writing the description has english as a second language and does not understand what kilns are all about. i hope you have not been cheated in buying this thing. read the description of the "temperature controller" especially the last sentence.
  23. i replaced my 4 belts by contacting Laguna.
  24. welcome to the forums, tabathos. what country? does your clay have a cone number that it is fired to? is it terracotta clay"? there are many other bits of information that would help someone who is familiar with your problem make a good suggestion. what suppliers are available to you? (Kaolin is a type of clay.)
