  1. I was going to use the large body part and could invert for casting if needed. When firing the slip with a solid neck and head I guess it's better to do slow firings to avoid cracks, etc. So I think my choices are to cut in to multi pieces and make neck and head solid with hollow body or attempt to cast neck and head as solid by putting the smaller objects on the bottom. Thanks everyone!
  2. Hi Mart, The thickness is 1.5"x1", rectangular shaped (not true to life shape) where the head meets the neck. Yes, I can and will try something more simplistic to start. I was worried about the same issue you mention (pockets) and I just wondered if there was a way to leave the slip in longer to allow the head and neck (if needed) to become solid. Thanks for your help!
  3. Plaster Model With Polymer Clay Detail

    Thanks Isculpt. I tested a piece of very dry plaster by first treating it with some coats of release (water and Oil Soap mix). Let that dry for a day. Then tried some craft glue (like Elmer's) and I was really surprised to see it did stick the 2 together well (at least for the little piece I tested). I really did not think the glue would adhere to the polymer clay or "Soaped" plaster but I was wrong.
  4. Plaster Model With Polymer Clay Detail

    Thank you Trina & jrgpots for the great ideas! Trina, we do have a glue called "Liquid Nails" and maybe that is the similar thing. Someone else recommended Latex Glue - I just didn't think that would stick to the plaster.
  5. Plaster Model With Polymer Clay Detail

    It will be a model for making a plaster mold. The mold will be for slip casting.
  6. Hi, I am not sure this is the correct place to ask but I hope someone will know the answer. In the attached photo there is a plaster model with polymer clay detail attached. How are they getting the polymer clay to stay on the plaster? Is this a certain type of clay or plaster? Is the plaster sealed? When I try this the polymer clay falls off and will not stick/stay on the plaster core. Thank you for any ideas or help with this question. Edward Jones
  7. Thanks for your help. I will give it a shot as is and see what happens. To make sure I understand, I could make neck and head separate castings from the body. Neck and head could be solid and body hollow. Then once cast join them together? Is there any reference (sites, articles) for joining cast pieces together that someone can recommend? i.e. if at an extreme angle (neck leaning out & not as vertical) will I need armature or supports? I guess it would be similar to joining other noncasted leather-hard shapes. Thanks again!
  8. Hi, I am new to slip casting, firing slip cast, etc and hope I can get help here with a few beginner questions. I am making a model of a giraffe and want to know what the best method to approach slip casting this form. The body of the giraffe will be hollow after pouring out the un-absorbed slip from the plaster mould but I am worried about the neck and head. The neck will be about 1.5" x 1" x 7" and the head about 1.5" x 1" x 2.5". Should I try to cast this part of the body solid or hollow as the body? Is there a safe guideline or ideal thickness for the walls if not making these parts solid? Is this controllable besides by how much (dwell?) time the slip is left in the mould? Are there tips that anyone can share to casting this shape or firing tips if making it solid? I have read about firing thicker pieces but I understand that this really should be avoided for the known reasons. Thanks for any ideas, help, recommendations, etc! Edward Jones
