To be gelled the specific gravity has to be lower-than-normal and then a flocculant added to bring it back to a creamy consistency. For many common partially-fritted glaze recipes this occurs around 1.43 to 1.45 specific gravity. The addition of epsom salts or vinegar to the slurry gels it and imparts the property of thixotropy.
