Hulk Posted December 6, 2019 Report Share Posted December 6, 2019 The Acid Processor is in the rolling mill. I worked in the sheet mill; just remember seeing the huge squarish reinforced fabric bags full of dry red powder stacked up over there, and also going out by rail (usually, sometimes by ship; never saw them loaded on trucks). My understanding is those interested in said powder use it for pigment, e.g. paints, coatings, etc. The Acid Processor area is something to stay away from, rather like the zinc pot (for those who don't work in the sheet mill, that is). Fascinating, yep! Best job I ever had, in terms of exciting and high energy stuff going on, micro community, history, sciency stuff, etc. … After x years of second round of college for computer science, got to see first hand semi-modern ("we don't fly to moon" is another story for another day...) process control...

liambesaw Posted December 6, 2019 Report Share Posted December 6, 2019 Very cool, if it was red powder in open air that means they boiled the HCl off and then continued to heat it to liberate the chlorine, smart move to deal with it all in one process. I originally wanted a chemical engineering degree but switched to computer science, wish I would have stuck with it since there's so much more practical knowledge.

You may get some suggestions but you will need to test anything suggested on your clay with your firing schedule. Glazes generally are not created specifically for once fire. Are you seeking a matte or gloss? Link to comment Share on other sites More sharing options...

It is a free resource and you will likely find some recipes to try. You will need to confirm that they work with your clay, your glaze and your firing schedule which will be a longer schedule resembling a bisque and glaze schedule combined together.

Hulk Posted January 14, 2020 Report Share Posted January 14, 2020 Tony Hansen has several clear recipes on his site as well, along with detailed discussion on materials, behavior, development, etc. https://digitalfire.com/4sight/recipes/index.html Hesselberth has some glazes listed on his site (colours only, no clears); see the notes - some he recommends, some not so much. http://www.frogpondpottery.com/tested-glazes/mid-fire-stonewareporcelain/ Link to comment Share on other sites More sharing options...
