Tri-Art Linseed Brush Soap

At Tri Art Mfg, they deliver not only the best product in the market , but the best of excellence in customer service I have encountered for an art store, period. I truly believe that Canadian made paints are the most superior among all premium art paints in the market , specially the acrylic. This statement is based on 27 yrs of paint preservation, with occasional usage, study of Stevenson's professional paint vs liquitex vs Windsor Newton. Canadian paint outcasts the other in viscosity and emulsify, the others became runny,deemusified- sedimented in 2layers,and dried up with the latter paints. After 27 yrs Stevenson's - Canadian made acrylic remained unchanged as first purchased. My only qualm, is this, and it happens on all paint brands, is Why Burnt Umber always tend to clump together too soon, after 6months or so, they look like **** from the tube. Hmm? Maybe it has a lower humidity retention ability in the atomical level. Enough said.
Thank you
