I started on my molds today. All of these castings will need a 2 part mold,, that's something that I haven't tried before. So It will be a learning experience for me too. I purchased a starter casting set from Micro-Mark and went to work on it.
As per the instructions I formed some of the" KLEEN KLAY " into a rectangle and pressed the masters into it. Then with some $ store foam board I hot glued a box around each one, and tamped down the edges of the clay to make a good seal.
I then mixed up the 1 to 1 rubber and poured it into the form.
About 5 hours latter I broke apart the boxes and pulled the " KLEEN KLAY " free as carefully as I could so I didn't remove the master from the silicone. In a little bit I'll make the other side of the mold so I can cast tomorrow.
