What we liked
- + Cobalt oxide is very strong, so a small amount colors a lot of glaze
- + Classic source of deep blue in glazes and brushwork
- + Made in Germany with consistent purity from batch to batch
Trade-offs
- - Toxic raw oxide needs gloves and a respirator when handling
- - 10 g is small, though it goes further than most stains
