The guaiacol will be a solid til even at normal room temp(at atmospheric pressure), but once it is melted(first) so you can work with it. then powder added to guaiacol and bb/ba added to guaiacol and powder... then heat that mixture... it will begin dissolving the powder.... keep heating til ALL the powder is dissolved!!!(the tiniest speck will act as a 'seed' to make it crash and form crystals around it!!!(think, oysters implanted with a piece of sand to have pearl deposited on the sand... you end up with a pearl, because that little speck acted as a 'seed' for the pearl(or in the case of tne, the test crystals) to gather and grow...)... once you have a complete LIQUID(no test crystals that aren't dissolved!), you will add the oil(or eo/oil blend) in dissolved test/solvent solution.. heat to 212F for 15 min more, just to make sure you are gtg... filter and bottle...
NOTE: Even if you are using EO, you can't get tne to hold worth a damn with only 3% guaiacol... bump the guaiacol up to 12%(15% if it's your first time), and it'll hold just fine at 100mg/ml(using, also, 2/20 BB/BA...EO is not NECESSARY, but you can use it if you want)
ALSO: Once this process is complete, you don't have to worry about the guaiacol turning back to solid..... If you use the correct method... I can't speak for some of the crazy things I've seen people recommend on the good ol internet!!!(by correct method, I mean that this is ONE of the correct methods... There IS more than one way to skin a cat!)
Help me please, with what filter 0,22 or 0,45?
