I am embarrassed to admit this but maybe it will save someone from something similar happening to them. Last week I was reminded a very valuable lesson to SLOOOOOW DOWN! I make batches of 5 loaves at a time and have what I thought was a pretty good rhythm in my set up and pours. Everything ready to go, oils heating up, water weighed, time to pour in the lye. I must have poured it too fast because my water/lye bath instantly exploded my pyrex bowl. I was so lucky it didnt explode right in my face, 28 ounces water and 12 ounces of lye and shattered glass all over my table and floor. what a fun clean up job that was but very grateful to say no harm to me. What an eye opener. After a thorough clean I made myself redo and finish this batch and will forever now take it really slow and careful. WHEW! Scared the heck out of me!
