While working in the studio this evening, I stopped for a second to look at my pile of reclaim clay. Typically it just sits there on the plaster bat and dries out slowly. But tonight something odd caught my attention… look closely at the bottom edge of the plaster bat!!!
Yep… there’s something “funky” growing down there…
Now I’m not really sure what’s going on here?! I probably should call my sister the High School Science Teacher. Or maybe someone else out there can explain this “fuzzy phenomenon” to me?!!! Either way, it’s pretty cool…
Sometimes sodium silicate starts bleeding out of plaster molds here is a link to some information about this phenomenon. it usually means the plaster is at the end of its useful life. maybe that is what it is. ishttp://ceramicartsdaily.org/pottery-making-techniques/making-ceramic-molds/casting-call-how-to-mix-casting-slip-for-sculpture-and-pottery-plus-3-great-slip-casting-tips/
