When you mix it right it will be thixotropic, that is, it will gel slightly and hold itself on the ware after dipping. This state can only be achieved if there is enough water for the epsom salts to do their magic. The watery nature of the slurry is nice for measuring specific gravity using a hydrometer (normally they don't float freely enough if the slurry is creamy). We normally recommend a specific gravity of 1.44 for this glaze, but in this case it seemed watery enough at 1.46. On use it will become clear if 1.46 is OK. How? It will go on the ware too thick. If that happens just add water to 1.44 and add more epson salts to gel it back up.
