  1. About 10 years ago, I took several ceramic classes and fell in love with the way Strontium Crystal Magic worked with other glazes. I attached a picture of Strontium Crystal Magic Warm with a spray of Water Color Green that I made in a community college class. Fast forward 10 years and I cannot get anything close to those results. The second picture shows the same glazes with a kiln controller set to a standard medium speed firing schedule to cone 5 with a 12 minute hold time. There are tons of nasty little pin-holes, and although I don't mind the color, it is nothing like I was expecting. The recipe that I copied from San Juan College is as follows: Strontium Crystal Magic Custer Feldspar 2400 Whiting 900 Strontium Carb 660 6 Tile Kaolin 780 3124 Frit 240 Lithium Carb 240 Titanium Dioxide 720 Bentonite 120 Total: 6030 Yellow Iron Oxide 121 (2%) Sooo... I noticed online that my SJC recipe has slightly different ratios than the one I found on https://ceramicartsnetwork.org/ceramic-recipes/mid-range/strontium-crystal-magic-warm/. Also, my copy from SJC says "6 tile kaolin" while the one on the website says EPK. Is my recipe written wrong? or is my firing schedule and temperature causing the pin-holing and color difference between the pot 10 years ago and now? I know that glazes are super complicated, but I just don't even know where to start and would really appreciate some help. Thank you for any help! Erin P.S. I am so sorry the images are huge... I wasn't sure how to re-size them
  2. Hi Everyone. I'm having major problems with pinholing and pitting. I am getting hundreds on pin holes on only the outside of small pots. I am using tucker's mid smooth stone and bisqueing to 04 with a 16 minute hold. I am dip glazing using amaco white with a 16 minute hold. I have noticed after I dip glaze that lots of popping bubbles appear on the outside of the pots in the glaze. More hold time? Is my kiln broken? Any help would be good . Thank you.
