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; 5-80 wt % of an aerosol forming material; and 0-60 wt % of an active constituent and/or flavorant; wherein these weights are calculated on a dry weight basis; (b) depositing one or more predetermined quantities of the slurry onto a carrier using a positive displacement pump; (c) setting the predetermined quantities of 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.

A method of reducing the quantity of a first constituent in aerosol generating material using an aerosol generating device configured to deliver inhalable aerosol to a user is disclosed. The method comprises performing a first aerosolization process on a portion of the aerosol generating material comprising the first constituent to generate an aerosol for user inhalation, and performing a second aerosolization process on at least the portion of the aerosol generating material until the at least the portion of the aerosol generating material is substantially free of the first constituent. Also provided is an aerosol provision device and an aerosol provision system.

Methods and vaporizer apparatuses that estimate, measure and/or predict the amount of vapor and/or material (including active ingredients) released by the vaporizer apparatus. In particular, described herein are electronic vaporizers and methods of using them that determine a dose/amount of vapor and/or a material in the vapor based primarily or exclusively on the electrical and thermal properties, e.g., power or energy applied to the vaporizing element (e.g., heating coil) and the temperature of the material immediately before and as it is vaporized. Dose information may be used to control operation of the device and/or reported to the user.
