I was prepared to buy cob media 20/40 at $32. per 40lb bag for blasting however I was told that a local company was getting much better results from using Glass Oxide at $8. per 50lb bag. Should I cob or glass blast an original 1920’s hand hewn cabin in NC, also the cabin has a chinking made up of a portland cement recipe.

You should be able to get the cob for about $10-$15 per bag. I’m not a big glass fan.
