<p>An engobe has more clay content than a glaze but has less clay content than a colored slip, which is a clay slurry with added colorant such as an metal oxide or mason stain. Engobes are often similar to underglazes, but I think with the the intention of an engobe to be applied more thickly.</p>
<p></p>
<p>Typical engobe recipes would look something like this, with a different recipe for each firing temperature.</p>

<p>Hello! I just posted a comment and was asking for this dry glaze application technique. I would like to know if the dry glaze is just the dry powder and if it is applied onto the newly glazed surface, still wet. I am tryin to achieve some superposition effects on plates and therefore, I should apply the dry glaze also underneath...</p>
<p>Many regards from Argentina!!</p>

<p>I have made a couple of recipes from down under and have used EPK in place of the Eckalite & they turn out marvelous. I can highly recommend Glazes for Australian Potters & More Glazes for Australian Potters by Janet Deboos. The More has some duplicates from the first one, but I like having them both. I picked them both up off E-bay for fairly reasonable. I haven't begun to try all the recipes(and there are alot!). jhp</p>

<p>Jan - Do you find any difference between Eckalite or Eckaglass? They seem very similar chemically.</p>
<p></p>
<p>In California I'd would use EPK kaolin from Florida in place of either Eckalite or Eckaglass kaolins due to cost. It's bad enough that we pay for Frost (very-white) porcelain clay imported from New Zealand.</p>
