Carson Posted September 4, 2013 Report Share Posted September 4, 2013 I'm back after I long hiatus! Pottery, I've missed you so. After careful consideration of my physical abilities I chosen slip casting molds as a start. I have made molds in the past and am now brushing up on the steps. I want to start with porcelain slip casting; however, I cannot seem to put my fingers on a supply of porcelain slip here in Palm Springs California. I looked at one recipe online to make porcelain slip myself and would like guidance on a good recipe for porcelain slip. Is it hard to make? If so, maybe someone could point me in a direction to buy porcelain slip here in the Palm Springs area. I am setting up the studio now and I look forward to getting started. Thanks in advance.

PeterH Posted September 5, 2013 Report Share Posted September 5, 2013 Carson, You mention buying ready-made porcelain slip or mixing your own. A third option is buying a premix powder (which includes deflocculant). I find it convenient to store and use, and it minimises transport difficulties. As I'm in the UK I cannot offer any advice on brand or supplier. Regards, Peter PS You might find this book on mould making of interest. http://tinyurl.com/mmqb43x ...mainly for its discussion of the plaster build up method. [Which - for a two-part mould with a flat seam - replaces the clay build-up by casting a plaster build-up. So an extra plaster casting step replaces the construction of a clay build-up. You place the cottle on top of the plaster build-up, rather than round the clay build-up. It's only $5 second-hand, so might be worth buying blind. http://tinyurl.com/kyvc5ul This needs a picture, but the scanner is fighting the low-res half-tone image in the book: Link to comment Share on other sites More sharing options...
