Anthracite doesn’t coke like bituminous, but it does like to “cook” a bit before burning. If you add it directly to the top of the fire, it will definitely spit and crackle, but if you add it around the outside of the fire and push it in as needed, that will help keep it quiet.
Be careful with that spitting: I was once bending over to pick something off the floor, when a glowing shard of rice coal popped out of the fire and into the gap between my shirt and the waistband of my jeans, right down the center of my extreme lower back, if you know what I mean.
