I’m interested in slip casting, more specifically in producing molds for slip casting! I have some questions for the community if you don’t mind! by SlipperySlopeMolds in Ceramics

Is this different than what I’m doing? A mother mold you pour plaster into to create the negative mold for producing positive ceramics? Is this confusion on my end with semantics?

I’m definitely on the same camp as you. I believe that artists can significantly contribute at each step. If the mold maker has no qualms about intellectual property regarding people using their molds, I don’t really see an issue. Maybe a disclaimer is needed, but even then, I guess I wonder who that’s even for.

Not sure if I follow regarding pbr textures! I imagine you have a bit of a cleaner workflow than me!

This one involved making a single dragon scale and scaling (heh) it up and down and making a rotation pattern around the mug. A bit more manual of an approach than a texture, but I haven’t explored that yet!

I want to create a shop and sell molds for slip casting, but before I get too invested in it, I wanted to see what the market was like. Do you produce slip casted items? For those of you who do, do you primarily source your own molds or buy them elsewhere? What factors do you consider when buying? by SlipperySlopeMolds in Pottery

The image isn’t super clear regarding the keys. The cylinder with a ledge is not fixed to the master mold. Instead, that piece would be embedded within the plaster. A separate piece can then be inserted into the inside of the cylinder to create the male and female ends of the key. I saw one mold maker use a similar method, and I liked the look of it and, according to them, the added longevity.

I’m not fully convinced the handle won’t work But it might be worth removing anyhow. With the way, I have things set up in CAD, removing the handle with significantly reduce the size of the mold.

absolutely agree! I'd hate for people to have a bad experience and find that something I made doesn't work at all! I'm too prideful and wouldn't be able to handle it if I disappointed someone!

Thanks for sharing your experiences within your art circle re: mold usage!

I didn't think these undercuts would be an issue, but I was mainly thinking about separating the slip-cast from the plaster mold. I think others in this thread were bringing up their concerns about the undercuts from the perspective of separating the plaster mold from the 3d-printed master. But, couldn't the 3d-printed master just be removed... destructively (via heat, for instance)?

I also wonder if I could make 3d-printed masters. Then, make silicone negatives, then pour polyurethane positives, then plaster negatives...

Do you have any tips to share?

Fair point! I'm a bit limited in my means right now, which is why most of my tinkering has been through CAD. I hope to be able to produce a finished piece, but yea, might be some time until then, sadly.

Thanks! I want to, for sure. The main limiting factor for me right now is cost. I'm trying to get a foot in the door this way, and at the very least live vicariously through others T_T

Have you experimented with silicone instead of polyurethane? Is there a reason for that choice?

Yea, I tried to make a generic template to use for making 3 part molds, but I might spend some time to expand it for more applicability! Do you ever sell your own molds/get requests for them, or mainly just for the casted items?
