Ok so we have already learned from Stacey that we don’t need to use a muller when only using micas but I am wondering about mulling times? I typically spend about 20-30 minutes mixing mine with my palette knife but I see a few on their Etsy listing stating that they are mulling them for an hour or more? Do they really need that long? Especially when making small batches. I genuinely only mix batches with 1-2 tsp of pigment at a time due to limited drying space.
