"Reusable Mold Materials?" Topic

I see there are several of these on offer, and would like to know which is best for picking up and retaining fine details?

ImPressive Reusable Mold Making Material (found on eBay). This one is supposedly food safe, which is a plus if you want to use it for making candy, cookies, chocolates, etc..

I'm thinking about scratch-building some small parts, and it would be nice to be able to copy them in a press mold, easily, without having to go the full silicone, reusable mold route.

Oyumaru – the first one I became aware of (also on eBay)

Blue Stuff (sold by the people that make Green stuff). Is this just a blue version of the Oyumaru product, since I see you can now get the latter in colors as well as clear material?

Any other useful ones out there, that can be rewarmed in the microwave, or hot water, and reused?

I see some recommend using Green Stuff, resin, plaster, and/or other materials to make the castings from them.

Thoughts?

Plastimold is reusable.You can use resin to cast using it.

Thanks for the suggestion.

I hadn't heard of that one.

I just recently found out about it. They show a how to mold at their website. They pour resin in the mold. It's the consistency of honey when heated in the microwave. I'm going to get some.

There is a microwaveable product call Composimold.

composimoldstore.com

You can buy it in bulk if needed.

Hmmm, that Composimold looks interesting too.

I'll have to compare pricing of the various options.

Warning, the Composimold volumes are off in the descriptions listed at the bottom, so buyer beware, e.g. the number of units in each pack. The ounce listings and prices are presumably, and/or hopefully, more accurate.

Anyone used Blue Stuff, and/or the Oyumaru sticks?

Composimold isn't very good for casting plaster & other water-based stuff (water dissolves it.) They supposedly sell a Composimold that works with plaster, but I've never seen it for sale on their site.

I tried some of the reusable molding stuff before and wasn't very pleased. You had to use low temp resin or the mold melted. Never managed to get a good pour. I recommend Smooth On company for anything casting related.
