You can see the greenish gray area on the top edge of the mould. That is leftover clay that has to be removed. I finish removing the clay, and sand down the glass moulds
This is how I finish the edges and remove the remaining clay.
I then brush out the mould to make sure that it is clean before taking a warm damp rag to go over it one more time.
After the mould is cleaned like this, it is ready to be placed in the kiln to be force-dried.
I found these cool little paintbrushes at Harbor Freight Tools. They are good for a lot of things in the studio and they are so inexpensive, I just throw them away!
At this point, the mould is still very wet. The plaster material with which I invest the mould has a very short working time (under 10 minutes on a cooler day). This means that most days in the South, you better have your plan together when you begin to mix, because on a 95 degree day with high humidity, the working time is more like 5-6 minutes. I still like this material very much.
These glass leaves will be installed at Serenbe in late October.
