stonehinge Posted January 30, 2011 Report Share Posted January 30, 2011 New to forums, and am hopeful that this is a place where creative folks share ideas and knowledge gleamed through their artistic journey. I am relatively new to clay, and am desperately looking for a matt grog type glaze that will look like real rock. Any and all variations....gray/browns. Have tried numerous commercial products with no success. I know I may need to layer an underglaze or two to achieve the variation in depth and color....but how in the world do I get a nice, rough, dry appearance to mimic stone??? I would also like to fire and achieve results similar to cement. I have googled every term I can think of, and have yet to find a glaze recipe. (Am hopeful for low fire technique....maybe 05/06) I have seen many completed works by various artists that seem to have found this secret. Any ideas or help would be so appreciated!

Chris Campbell Posted January 30, 2011 Report Share Posted January 30, 2011 This will be so much fun for you to play with ... And really, at this point you should be playing! Make some test tiles from the clay you want to use. Then buy the underglaze colors that come close to the shades you want. Then use sponges, cloths, screens, old filters, cheesecloth ... Any old thing that looks right to apply layers of color. Fire, adjust and try again. You can also take some of your clay, dry it, crush it to powder and sprinkle it over the wet clay. This is the fun part ... Take all the pressure off yourself to DO IT RIGHT and just explore! Let us know how it goes. Link to comment Share on other sites More sharing options...

THANKS As Chris says playing around with the ideas will help. At the same time you need to determine what type of surface you want. Granite, marble, lava etc. Looking at the characteristics in the stone may lead you to a variety of techniques that would involve spattering with course or fine spots, dragged surface color, or even lava type glazes. The best way to learn is to play , but record both your play and your results. As you go you will become more in line with your desired effect, and be consistent in getting it. good luck!

GEP Posted January 31, 2011 Report Share Posted January 31, 2011 A lot of my glazing is meant to mimic stone surfaces, though somewhat abstractly, not really an exact replica. I think my most important glazing tool is a small, low-tech, mouth-blown glaze sprayer. There are lots of ceramics supply outlets that carry these, just google around and you'll find one. They cost about $20, and they are fun to use. Mea Link to comment Share on other sites More sharing options...
stonehinge Posted February 2, 2011 Author Report Share Posted February 2, 2011 Thank you for the replies and encouragement. Will try some new techniques....wire mesh and maybe the sprayer. I think these could help achieve the under-glaze 'speckling' that happens in ordinary rock. I think I am still looking for an overall application of a flat browned sludge-groggy mix that pulls the whole piece together. I know there are recipes out there somewhere that wash over the underglaze pulling the whole piece together to look natural. Have looked through many glaze books, but no success. Thanks again! Will keep looking..... Link to comment Share on other sites More sharing options...
Chris Campbell Posted February 2, 2011 Report Share Posted February 2, 2011 This can be achieved by using colored clays too. If you color the clay you can make a thin sheet of the color you want for speckles, let it dry then crush it with a rolling pin. Then quickly mix this into your base clay ... The speckles should stand out. You can also mix in mason stains until you get a speckled look. Link to comment Share on other sites More sharing options...

THANKS You might try collecting wood ash for a 'grog type glaze', red pine for ochres, eucalyptus for greens, if results are too matt, add some 05 base,or lower, http://bonsai-handma...s.blogspot.com/ (new to blogs) Link to comment Share on other sites More sharing options...
Marcia Selsor Posted February 8, 2011 Report Share Posted February 8, 2011 The new designer underglazes from AMACO are speckled. Maybe this would be a more simple solution. Marcia Link to comment Share on other sites More sharing options...
