Moldy molds

Hi all, I recently learned to slush cast in latex. After about a week, one of my plaster molds grew mold (as in fungus) on the outside. It's definitely mold (a yellow coating with green spots), not…Continue

Configuring Linux Stopmotion with DSLR camera and lossless export

Hi all, I wanted to share a solution to a problem I was having, in case someone else finds it useful.There's a free program for Linux called "Stopmotion," which lets you capture and preview animation. Unfortunately, it's meant for webcams. So even if you can turn your DSLR camera into a webcam, it will just grab the latest frame from the live preview, instead of triggering a shuttered exposure.Here is how you can fix that: First install gphoto2, which is a command-line tool for controlling…See More

"...And I imagine, like all living organisms, the mold wil prefer the nutrition of corn starch to talcum powder (which is basically ground-up rock and perfume)"

"I think mould spores are everywhere, so if the conditions are right the fungus will grow.  So drying the plaster mould is probably the best approach.  Liquid latex works best in a dry mould, the dry plaster absorbs moisture from the latex.…"

"And don't forget to dry your mould out gently in the oven once it has set. They contain quite a lot of water - all that you mixed in!"

"You could also try add some anti fungus product - like the ones you use for making marmelade, to the plaster while mixing. But without sugar!! Don't know what that would do to the plaster, but nothing good I gather. Best of luck I hope your…"

"Hans, thanks for the advice. I think you're right. Even after I switched mixing container, a newer plaster mold has also gone bad. More info: Yes, it has been very humid where I live recently (although I did not wrap the molds in plastic).…"

Hans Jacob Wagner replied to Sal Elder's discussion Moldy molds
"If kept in a dry environment and not encapsulated this shouldn't be a problem. Sounds like the mold has be damp for an extended amount of time and not have had the chance to dry out after use. Keep your molds in a heated room like your boiler…"

Moldy molds

Hi all, I recently learned to slush cast in latex. After about a week, one of my plaster molds grew mold (as in fungus) on the outside. It's definitely mold (a yellow coating with green spots), not mineral deposits. Has anyone else seen this before?Some info: It's plaster of Paris. I did use an old milk carton to mix the plaster---maybe I didn't clean it well enough. I've also been using corn starch instead of talcum powder for de-molding, so I wonder if that is feeding the mold.In the…See More

Choice of sculpting materials for moldmaking

Hello, I haven't done any moldmaking but would like to try it. I've seen Nick Hilligoss's great video here: https://www.youtube.com/watch?v=5fWdZnQRzB0. My understanding is that I'll sculpt in one medium (eg NSP) and use another (eg water-based clay) to define the two halves of the plaster mold.My question is, is there a rule for deciding whether the two clays will stick to each other? In the video it seems important that NSP doesn't…See More
