Glaze Mixing Ques.
Why does glaze have to sit for 24 hours after being mixed? My husband
asked me this question and I didn't have an answer for him (besides "that's what I was told to do"). LMac |

LMac Don't you hate when your husband ask silly question? Who is he to question your teacher? :-) Truth is, there is no reason you have to do this. Sitting over night may change the glaze consistancy and viscosity if the materials used are somewhat soluble (e.g. gerstley borate), but there is no rule that you have let glazes sit overnight. Mix the glaze well and sieve, and it should be fine to use immediately. deg |

also gives it chance to settle so's you can adjust the thickness (and the
air bubbles can leave as well....) One of my glazes is best when it's been left for a year in the bucket...... Love Eddie "Dewitt" wrote in message ...

I am one of those people that like to let the glaze sit over night. I usely
measure the specific gravity of my glazes right after mixing them as with some glazes it changes enough over night for me to make an adjustment to the sp. I guess it depends on how fussey one is about the consistancy. I do a lot of layering of glazes and I want control on the thickness of the glaze. I also like to make sure I don't have too much floculation. Sometimes if I add something to decrease the floculation it takes some time to take effect minutes, hours or overnight I am not sure.
