  1. Hello all! My partner and I want to slip cast cups, I have a bit of an idea when it comes to ceramics (thanks mum) but have some questions :) We have found a clay that already has a speckle in it - can we use it to make slip for casting? If the clay cannot be made into slip - is there something we could add to plain slip to make a speckled look (that's food safe)? Can we add pigment to clay/slip that already has a speckle? Would this interfere with the chemistry? I know the other option is to use glaze to achieve a speckled look but we would prefer that it came from the clay. (the speckled glaze I have used in the past is glossy and we want a matte finish) I've attached a picture of the look we want to achieve with slip casting - I hope this helps Thanks everyone xx
  2. I'm new to painting on ceramic tiles, and I was wondering if someone could help. I recently learned how to paint on white matte tiles (ceramic / porcelain - paint cures at 780 Celsius = 1436 F). I live in Brasil, but I'm moving back to the US in the next few months. I can find the products here, but I can't seem to find them in the US. The person who taught me doesn't speak enough English to know the English terms for Google purposes. I'm looking for two things: 1) powdered pigment colors - the guy who taught me buys from this store (it's in Portuguese) and the word they use is "esmalta". Google translate says this is enamel, but I'm not sure that's completely correct. I've found powdered enamel, but not for the temp that I need. Does anyone work with this? Can you give me some google terms to use? Or even a website that sells specifically for this temp? 2) The other thing he uses to get the paint to stick to the tile is "veiculo oleoso (pinho)" which I assume translates into pine oil medium. I know this exists, but I again, I can't find it anywhere on any art supply sites. Any help here as well? The product looks like this (again in Portuguese) This guy buys from these stores, but also buys direct from the various porcelain factories in the area, too. Apparently it's pretty easy to find here in Brasil. Anyway, any direction would be great. Thanks.

    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
