2. Once the s.g. is correct adjust the fluidity with a deflocculant such as Dispex. Even if using sodium silicate for deflocculation I find a few drops of Dispex markedly increase the fluidity giving better casting results
3. If you are using molds that have not been used for some time a fine misting of water on the casting surface will help prevent air bubbles in the cast

Very helpful information indeed - from a very knowledgeable source. Goof stuff, keep it up.
Thanks Eugene for your support. Planning regular posts of how to's and hints and tips
I have a mould I wanted to start using again so these tips couldn't have come at a better time...thanks!
If I can offer any other suggestions that could help please let me know
I want to start using a few molds once I get moved, so now I know where to come to refresh my memory of your helpful hints, thanks so much, love your work.
Hi Linda, Thanks. Also check out my posts on paperplaster, truly reolutionary!
Hi John, I will check out your other posts. Thanks so much. I took a workshop with Sandra Black and she gave us a paper plaster demo, very enlightening as those molds can get quite heavy otherwise.
