Is fumed silica thickener the same as rigidizer?  I am brand new to smiting (still waiting for that first hammer blow) and setting up my shop. I live in an area that is currently under Covid Lockdown so I'm looking for options on amazon to pass the time.  I can find "Rigidizer" for $30.00 per pint or a gallon of "Thickener" for $18.00.  Are those the same thing ?

Thanks, and apologies for the ignorance.
