Kilimanjaro and other African meerschaum are all block. So-called African meerschaum, of which there were many, many brand names, mostly made by Kiko (including Kilimanjaro) were from a mine in Tanganyika, and production ceased supposedly because the mine went dry, they literally mined all of it. It's much more dense than Turkish block and won't color on its own, so was often treated with a calcining and coloring process, turning it either an all-over yellow, red, brown or black, or a cream color fading the black at the top. It's not pressed/chip meerschaum, it's just a different kind of block.
Here's a calcined/tinted African pipe by Kilimanjaro, of the color I love, mottled tan with a black-fumed rim

Pressed meerschaum was used for some antique pipes. Strambach used it for calabash meerschaum inserts, and I believe Pioneer did too (the common calabashes with a conical black ferrule and Danish Freehand-ish black stem). Some Turkish-made minis and very small non-minis have used it. I think many new calabash cups use it. And last, the cups in meerschaum-lined briars are almost always pressed. Aside from that, I think everything is block.
