Hello everyone,<div><br></div><div>I am researching some murals on canvas from the 1920s that were adhered to a wall with a mixture of &quot;paste and molasses.&quot;  These works of art suffered multiple forms of abuse over the decades, including being wallpapered and painted over, and today they appear very dark yellow.  What I am wondering is if the molasses could be partly responsible for the yellow color.  I did a google search that revealed that molasses is acidic (PH 4-6).  If anyone has thoughts on this matter I would be most interested in hearing them.</div>
