Ok, I haven't posted because I have been trying to think what of all the blunders I have had I could move to the level of the "biggest". Well I had it today and I'm still kicking myself. I have been making glazed since almost day one. Chemistry was a class I was always comfortable with and the work of making glazes seemed simple beyond thought to me.
Today I was using a triple beam Ohaus scale to make up 10,000 gms of glaze. I had never used this scale but it seemed straight forward and easy. I hung a 1000 gm weight on the end and started measuring out glazes. The studio was busy with people in and out so while I was being very careful about writing down each measure and the ingredient I was only half conscious of how things 'looked' and 'felt' and it has been awhile since I have made up glazes. Things seemed wrong in that the measures seemed far greater in volume than they should be and by the time I had all of the ingredients measured out I had half of a 5 gallon bucket filled with dry ingredients. I thought 'this cannot be right. Something is wrong.' I then zeroed out the scale, put a 500gm weight in the bucket and then hung a 500gm weight on the arm. The arm did not budge. I added another 500gm and then another into the bucket. I have no idea what is going on but I sure in hell have a bunch of dry material that there is no way I can now make any use of.
