AskaDave''sGardener:Dolomite
Apr 03, 2015#0183;#32;Dolomite lime is/was a fairly quot;hazardousquot; form of lime (you definitely don''t want to inhale it.) I don''t know about mixing borax and Epsom salts, but if you can find calcitic lime (typically available at feed stores and larger garden centers), you can mix it with Epsom salts I''ve seen ratios online for creating an approximation to dolomitic lime.
