Waxing or contamination in bho using CRC

[cyclopath]

Thanks for getting back with your preliminary data @Dextract

different dirt. but apparently this still applies…

@cyclopath

I will repeat that the wizard said the magic dirt MUST BE DRIED to work, AND, currently 100% of the “failed to work” were not dried.

although with the opaline silica, there were absolutely reports of success with out prior drying…

@cyclopath

if @Dred_pirate didn’t dry it, and it worked, then perhaps the wizard just has a thing against water

@Photon_noir

The glass should be placed under vacuum on a Schlenck manifold, and heated with a torch to burn off the internal monolayer of water chemisorbed (hydrating) the glassware. Then the Schlenck should be used to fill the flask with dry N2. After fire drying, perform chemical operations in a desiccated glove box in case of small leaks.
