Our 12 string bone go to saddle material!
I usually route out a wider saddle slot on my better 12 string guitars, and compensate the octave up courses separately as much as I can, so we can stay in tune up the neck. These were not quite wide enough to make a fake adjustable saddle for those 1960s Gibsons, but making a nut that seats on the bottom of the slot, and allowing the adjusting screws to remain just for looks, will really make that 1962 or later Gibson J45, H Bird, Dove, Epi Texan, Pioneer, Excelente, Cabellero, or other guitar sound much better too. Allpart's bone is usually very good quality, and consistently so. Shaping a compensated 12 string saddle is not for the faint of heart of an easily acquired new skill. Make your saddle peaks flow into each other with a round file, and some sculpted fluidity, or the bone will chip.
