  1. i ask because a recipe i'm looking at calls for Calcined Kaolin. Instead of calcining it myself, i went to Ceramic Supply to ask for Calcined Kaolin, and was handed a bag of Calcined China Clay. Just want to make sure it's okay to sub in my glaze recipe. thanks
  2. Is Calcined Kaolin the same as Calcined China Clay?
  3. do you all use your glazes on bisque ware right after mixing/sieving? or is it best to let the glaze sit for a day or two to fully blend?
  4. Min, I would love the have the recipe for that clear glaze that works over underglaze, if you don't mind. Thank you!
  5. Thanks, Min. I will try the line blend as you suggested. If I find that #3 is my winning formula, do I just continue to mix both glazes as normal and then combine in the proper proportions? Re: my clay -- I am using Standard 551 VP Porcelain at cone 6, and my cones are indicating that i'm hitting between ^6 and ^7. And pots fired using other glazes aren't leaking, which leads me to believe the glaze is the issue here. I appreciate your insight and the recommendation of G2934. I'll try that one as well.
  6. Hi friends - long story short, I'm on the hunt for a matte white glaze to use on porcelain mugs and bowls in cone 6 electric/oxidation. I really like a stony/eggshell surface, but I have been running into a bad scratching/staining situation with the glaze i currently use -- plus, some of my pots have a slow leak, even when this glaze is only on the outside of the pot. part of the problem is that the origins of this recipe are unknown - i got it from the art school where i take classes. so i have 2 questions: is it possible to diagnose my problem just by looking at the recipe? and is there a way to adapt this recipe to make it work on functional pots? Here is the recipe - at my art school, we call it Mullen White. Kona 60 Spodumene 10 EPK 10 Dolomite 16 Zinc Ox. 2 Titanium 2 I really appreciate any help or suggestions you can provide. Alternatively, if anyone has a successful recipe for a matte white in cone 6 oxidation, I'd love to try a new recipe! (I have mixed up some VC71 in the past, but it's too satin for my taste...) thank you in advance, karen
  7. Hi all - I'm new to mixing glazes, and found a recipe that calls for Zinc Oxide. Is that the same as Zinc, or are they two separate ingredients ? (All they have at my local Ceramic Supply is called Zinc.) Thanks in advance, Karen
  8. Thank you both for the feedback -- i really appreciate it. Mea, you're the second person to endorse the Undercover so now I'm leaning that way. How does your Undercover tent do in the rain?
  9. Apologies if this has been covered in other areas -- but I'm looking for advice on buying a white tent to use for the outdoor craft show season. I'd like a 10x10, white, rain-resistant (if not totally waterproof), and most importantly, easy to transport and set up by myself. (Sometimes I have help, and sometimes I don't.) I've read dozens of reviews on Etsy/Amazon, and gone through some of the posts here -- the leading contenders at this point are Undercover, EZ Up, or Caravan. Would like to spend $200 or less. Can anyone offer advice on what to buy or what to avoid? Many thanks, in advance. Karen
  10. i have a large bucket of seived porcelain (same clay that i throw with). if i want to add some mason stain to some of this slip to make a decorating slip, is there a rule of thumb for slip/stain ratio? (i've seen ratios for dry clay....but is there any guidance on adding stain to already-processed slip?) thanks, dp
