The effects of preaggregation silicate crystallinity and postaggregation silicate crystallinity on the 11.3 μm structure in comet dust emission have been calculated. Of the order of 10 - 20% crystallinity provides the best agreement to date with observation but the fits are not yet fully satisfactory.
