How the Calculator Came to Be

The recipe shared by Lost Art Press was written by volume.
4:4:1 ratio of gelatin, water, and salt

Measuring powders by volume drives me crazy, so I decided to measure it once by volume but weigh the results for future reference. My attempt at converting that ratio gave me about 84 g gelatin, 128 g water, and 32 g salt. I used 84 g of gelatin because that’s the size of a standard supermarket package, and it makes a reasonable amount of glue for small projects.

Shortly after my first batch, Megan Fitzpatrick from Lost Art Press generously shared the large-batch recipe they use. I scaled everything down from that and when I compared the two versions side by side, the numbers were reassuringly close

I trust the Lost Art Press numbers more, and that’s what powers the calculator here.

You simply punch in the amount of gelatin you have, and it instantly gives you reliable weights for water and salt, no more fussing with measuring cups.

A huge thank you to Christopher Schwarz and Megan Fitzpatrick of Lost Art Press for their help and their willingness to share knowledge so freely.
