    I'm trying to remove the amber color of co2 extract via BPC grade powdered activated carbon and a celite filter, but haven't had any luck so far. If anyone has tips for this process I'm all ears. Tried adding 60°C heat for an hour and a half to no avail. Also curious if anybody knows what actually causes the amber color?

    To be clear you're talking about cannabis extract? If so it's amber naturally. I'm sure you know this to be doing this process. So is your product darker than rosin?

    Yes, I'm aware this is the natural color of co2 extract. Given that some come out a darker/lighter amber I'm trying to understand what dictates the degree of color, as well as how to remove it for imrpoved curb appeal

    Take said co2 lil
    Soak 10:1 in 200 proof ethanol
    Freeze, freeze, freeze
    Add dry ice to cooler, place extract wash. Keep freezing down to -40c if possible.
    Now run thru buchner funnel with fritted disc, and a good layer of aluminum oxide (prewet before running extract wash thru).

    Filter
    Evap
    Purge
    Done

    And people wonder why concentrates cost as much as they do. A lot of equipment, work and especially knowledge.
