ArtMolds Fine Iron Powder for Cold Casting and Molding - Polyurethane Resin for Making Sculptures and Statues | Home and Office Decors - 1 Lb/325-mesh

Mixed this powder with chalkboard paint for a chalkboard wall in the kitchen. Painted 6-8 coats and it works great, depending on the strength of the magnets. We purchased some pawn-style magnets that hold up to 5 sheets of paper to the wall with no problem - even have a calendar on it with a magnetic hook!

I have no issue with this powder. I was using another brand which upon inspection has a brighter copper color compared to this one which comes in a darker brown tone, but in using it in cold casting where you dust with it after making a thick slurry in the resin, it shines up just fine. I've also mixed it with the brass powder sold by this company, to get a nice tan color. Just mix the powders first before adding to resin.The key to any cold casting is to ensure you have a top metal powder layer otherwise it will always turn out dull because of the resin itself. The resin mixture needs to be dense enough to avoid soaking up the dusted powder as it will sink into it if not enough powder was used initially in the pour or coating. For reference I'm using Art 'N Glow epoxy resin, to get my results.Also - regardless of vendor, Brass powder is not yellow. If you want a brass color you have to mix it with the copper powder, otherwise it will turn out green from start to finish.I mainly switched brands because this vendor utilizes free shipping through amazon where alternatively I was paying quite a bit more going with the other company.

This is exactly what I needed. I have been using metal effect paint and wondered if I could make my own. The first batch if iron I ordered was the wrong kind, but will be used to make magnetic slime so it won’t go to waste. This iron will rust, which is exactly what I wanted it to do. I am running tests on the right mixture of iron powder to paint to get the best results. As a test, I brushed some of the powder on a tester card and sprayed it with the oxidizer liquid. It worked beautifully. I am really happy to be able to create that rustic vintage crusty/rusty look to things.

I will be using it to make my own crystals and orgonites

We use the power for a science project.It was awesome
