SAS Pottery Posted September 11, 2012 Report Share Posted September 11, 2012 I decided to try a new terra sig recipe using Suzane Storer's Newman's Red recipe - I am hoping someone else has tried it as I am having a few questions re: the outcome. As a recipe it turned out "fine" - specific gravity was slightly over 115 but I mistakenly used a "double" portion of Sodium Silicate (I may have defocculated it too much as I didn't get a noticable "mid-layer") - It brushed on OK using a completely dry red clay body as a test piece. However, it dried out almost as fast as I brushed it on - even with the usual 3 coats. I had difficulty getting the usual "terra sig magic" burnish and it left brush marks (not expected but not entirely dissatisfactory as it gives the piece a "woody" look). My current concern is that it will "flake off" in either the bisque or saggar firing I had planned to do with this particular recipe. Would raising the specific gravity with more water slow the drying problem/brush strokes?. I'd like to get some feel of an answer before using what I have on other pots. Any thoughts from the terra sig users? Storer's recipe is using 4gal of water:20 lbs clay:60mls sodium silicate. I made only a small batch to test it out. Not wanting to be wasteful, yet by deflocculating my batch too much is it a "gonner" and just try again? Thanks Link to comment Share on other sites More sharing options...
