  1. Hello wizards! I’ve been given a load of red terracotta clay which is wetting down. I am just browsing my glaze recipe book for a nice earthenware glaze recipe and see there are two sections Temps 1050-1100 and 1100-1150. Is any temp within this range ok? I am guessing it just effects the darkness of the clay? I am firing in a fast fire gas kiln. Havn’t used or fired earthenware before. Will be making functional ware. How do you chose which temp to fire to? I have always just gone with the temp of the glaze i like when firing stoneware, is there anything else to it? Many thanks
  2. Hi Bill, Thanks for sharing your groups test results, looks very accurate and scientific, but I can read the general firing schedule without knowing the measurements of oxygen etc. Is this chart recording a firing of cone 10 in 5.5 hours? How did they achieve the fast rate of the last hour? I am firing again tomorrow, quite excited. (But have forgotten to buy cones which is a bit annoying!)
  3. .. On this note @High Bridge Pottery - Excuse my ignorance - How are you supposed to see when the cones have gone? I opened up the spyhole but the heat is so blinding - do you use some special dark goggles or something>??
  4. Ouch. There are literally so many elemts to the making, glazing and firing process that can go up. Good luck for the next batch!
  5. THanks Patrick =-) Good to see pics and hear of home made kilns pros and cons.. love the glass of red you had to put down to take the pic lol. The hood worked fine, maybe could have been a bit wider actally as it was getting pretty hot and the finish kind of shmooshed like you said but otherwise pretty happy. I found a manual online which described how to make a hood with dimensions and it pretty much matched up what we came up with so that was cool. Gonna do another firing this week hopefully and test out top temps with some ash glazes. S
  6. Think the splintering noise was fine whatever it was as the pots came out pretty well. I have some black clay that I am trying to find the correct firing temp for with a few glazes I have made up. The small plates I have made on the lowest shelves have all melted but the cups were all fine.. I think it must be something about how I have made the plates. I think soaking will improve the next firing to even out the heat as there is a big discrepancy between the top and bottom of the kiln. Thanks for the encouragement, I feel like i am picking things up all the time =-)
  7. Hi Babs, Thank you for your reply.. no I am in Cornwall, UK =) My little port-o-kiln must be over 40 years young I reckon and it's a mystery as to how she got here, it's in good nick and has probably passed through may hands. Thankyou for the tip re John Eagles, very interesting man and work. I can't find the specific article you recommend but will have another look another day just in case I can unearth it. S
  8. Yayyy!! Well - it may be a disaster! Will have to see. I did want to soak or stall it at 1260 but I lose my nerve a bit when it is roaring and so hot... I tried to keep one burner lit for cool down so it went down slowly but flame kept licking back down through the other burner hole and I just switched off and closed it up. I did hear like splintering noises which made me cringe - do you know what that might be?? Good to hear about your own methods - what do ou mean when you say it prevents the reduction from penetrating? Are you firing above 1300? I think I will struggle to get mine up that f
  9. Hi Neil, Thanks so much for this. I found your analogies and openness really useful. I chose a gas kiln because I am an analogue girl, and I kind of think of gas firing a bit like photography, the kiln and the camera being very alike in their unique and magical ways - and much of what you wrote atested to that. I like the use of breathing and the circular movement. Anyway waffle waffle.. I decided to go for it and lit her up at 9 this morning. She is a bit of a galloper being quite small, so had to just keep it as steady as I could. I put it into reduction at 1050 as recommended in my fa
  10. Hey Liam, Thanks for your words of wisdom.. I felt pretty good about going for it, I just needed to ask around for some reassurance that I was on the right track. I fired today, lit it up at 9 and finished at 5. Felt prettty relaxed about it, and seemed to go smoothly, guess I'll find out more tomorrow when I get a peek inside!
  11. Hi folks, I am new to this forum and apologise if my questions have been and gone before, I’m sure they have! I have bought an old gas fired port-o-kiln and have had in installed into the granite lean to which has a tin roof, at the end of the stables (no horses in there anymore) it seems like a good space. Its small but there is air flow. The kiln is small, it has two burners in v good condition and I have a19kg bottle of propane for it. The kiln didn’t come with a flu or hood so I have got someone to fashion a basic hood and chimney to take the heat and fumes out. There is about an 8
