Hello,
I am just posting here another Delft Clay question and an answer to my own previous posting about Delft Clay.
Through trial,error,emails ,etc I have finally found out that the "Side Hole" in my casting rings was actually made to be used as a pour in hole for flat objects. It does work very well, but when I used the side hole for casting a ring, the results were not that impressive...Maybe someone could explain the process ?
I followed the 3 Youtube clips by Andrew Barry, these were pretty good and made my first attempt passable, I am however quite a harsh self critic so there is always room for improvement.
Back to my question this time, Having followed the Youtube videos, the one thing I found a PITA (Pain in the ass) was re-using the clay.
I hammered the clay back in place in the rings, but I found that even though I used 2kg of Delft in a 100mm ring set, the second casting was trickier as the clay seemed to have shrunk /reduced by quite a bit...Maybe I hammered to deep ? But the detail was amazing, exactly what I was after.....So do I transfer my delft into a smaller vessel and re-cast or do I buy even more clay to completely pack the rings solid with clay ?
The loss of delft from the first casting was minimal around a tablespoon worth but the compacted remaining clay when hammered, left a gap between the clay and the desk top edge of the ring,this moved when I pressed the flat object and I had to keep pressing the clay back towards the flat object...It didn't feel that secure but to be fair it worked.
Any help will be appriciated.
