@N P Kremer Pigments is also one of the best suppliers for non-toxic, natural pigments.

@Shannon Carpenter Coarse sand is better. But we did build this Florida cob with "playground" sand, which was quite fine grade. Ideally, I would use a grittier sand though, like a masonry sand.

Yes, pigment can be added. I usually add it for mine, unless you find different soils with different natural pigments. You can order them online. They come in powder form. Careful with the conventional concrete ones. They're good, but some do contain toxic ingredients so just don't breathe them or leave them on your skin. Yes, the RE pigment and lime plaster/tadelakt pigments are the same products. I don't think I have any videos on the Florida RE columns, but I have this recent video documenting a lot of the process: https://www.youtube.com/watch?v=MCVXLsgGIrI&t=39s
Florida Cob Cottage - photos
Here are some photos to preview for the case study on the Florida Cob Cottage build we finished a few years back. This one was an interesting build, and a lot of good lessons were learned for huge improvements. Florida is a tough place to build cob, not because of the weather, but because the soil has very little amount of clay content. I'll get into more specifics in the video case study. Please leave your questions here!

@Charlene Shawl Cool! :) Were you able to find one with a straight blade? I know a lot of them are sold bent a little.

@Charlene Shawl Yes, that was a great time! Fond memories from that class, for sure. I'm glad you're staying in touch! I'm thinking those J bolts should hold up for a long time since they're mummified inside the cob walls, unable to get moisture on them. Plus, they're galvanized metal.

@N P I'm honestly not sure! That's a good question. I've always received them only via email too.
