The invention relates to a method for the preparation of a sheet of a material containing alkaloids, said method comprising: grinding a material containing alkaloids to a powder; combining the powder with a binder, an aerosol former and water, so as to form a slurry, wherein the slurry comprises: the powder of the material containing alkaloids in an amount comprised between about 40 percent and about 70 percent of the total weight of the slurry; the water in an amount comprised between about 30 percent and about 55 percent of the total weight of the slurry; the binder in an amount comprised between about 0 percent and about 1 percent of the total weight of the slurry; the aerosol former in an amount comprised between 1 percent and about 5 percent of the total weight of the slurry; applying the slurry to a substrate sheet including fibres so as to form a sheet of a material containing alkaloids.

A method of making an amorphous solid is provided. The method comprises: (a) forming a slurry comprising: 0.5-60 wt % of a gelling agent; and 5-80 wt % of an aerosol forming material; 0-60 wt % of an active constituent and/or flavorant; wherein these weights are calculated on a dry weight basis; (b) shaping the slurry using a stencil; (c) setting the slurry to form a gel; and (d) drying the gel to form an amorphous solid. Amorphous solids provided by the method, articles comprising the amorphous solids, and non-combustible aerosol provision systems comprising the articles are also provided.
