  1. Working With Pure Pigments

    I have a considerable collection of pure earth, ochre and oxide pigments and oxides which I purchased for my encaustic medium via http://www.earthpigments.com. I would like to better understand how I can use these in the creation of stains and engobes. Do any of you do this? Might you have recipes or general rules of thumb for me? I see a lot online about "ceramic pigments" but I am pretty sure these are formulated, not pure. I'll happily text the options, but would love to hear people's experience first as these pigments are expensive and hard to get from where I now live in central Chile (by way of Boulder, Colorado). My main ceramic medium is porcelain, and I prefer to fire to cone 11/12 for translucency. However, I am concerned about burn out in the colors when using pure pigments and am happy to try cone 6 to maintain color. I will also test on terra cotta and stoneware. I am most interested in painting raw porcelain with the stains and/or engobes and doing a single firing, but I'm wide open. I am a beginner, really, with lofty aspirations. I love the work of Michelle Summer and am looking for a similar effect. I'm I right that the running in the work is only achievable with the clear glaze on top? Is she using underglaze, do you think? http://4.bp.blogspot.com/-mTkhN5hewWU/T4m5nVRXpWI/AAAAAAAAAbQ/jNHD6-jMdjw/s1600/DSCN2916.JPG I have seen this "bleeding" color under clear glaze in a lot of Japanese work lately. Am I correct that this is engobe + clear glaze? So, a couple of questions in this one. I appreciate any info you can share! Direct experience, links, anything. Warmly, Heather
