Hello, I sculpted a scenery item using a oil/sulphur plasticine type clay. I know that this material can inhibit mold curing. What is the best sealer for this clay? I plan to make a brush on latex mold. I think I have some Future on hand and was hoping to use that. Thanks! |

Back in the day (1960's-70's)we used to use banana oil for sealing plasticene. Don't know if it's still available, but I should think so. |

I always wondered what "banana oil" was. Let me refine that a bit. With a degree in organic chemistry, of course I know what it is. I just wondered what it did to the plasticine. |

The Banana oil solidified the outer layer of the Plasticine. At first it supersaturated it, so the 1st millimetre depth of the Plasticine, as it became oily, could be moved and smoothed. Then it dried out and all the elastomers/polymers leeched out, leaving something that, a year or two later, if you tried to scrape it off, crumbled like dried up clay. But, while you left it alone, the surface was hard, took paint and weathered well. I've no idea if the formula used in 60's era Plasticine is the same as today's super child friendly Plasticine. So the result may be totally different. Experiment! |

Sulfur can inhibit RTV curing but you are going to use latex. I would try out a sample on that without any sealer – I suspect you will be okay. |
