as it happens, I batch CRC’ed the output from 20 runs today…used three 5.2kg bags of dirt.
this version which @Photon_noir shared over in the Opaline Silica Thread somewhere shows a 6x48 CRC that we used for 5-8 runs before refreshing the media.
My current batch CRC uses two such 6x48’s so I can switch between them (so I always have a fresh bag of dirt on hand)…
I can’t share an SOP, mainly because I’ve not performed this trick twice the same way yet. Melting stuff down to CRC sucks. much easier not to remove all the solvent in the first place.
I proposed color swatches on the ceiling of the booth. boss insisted on boats
