But agar’s superior qualities come with complex chemistry. “To speak of agar as a single substance of certain (if known) chemical structure is probably a mistake,” wrote phycologist Harold Humm in a 1947 article. According to the Food and Agriculture Organization of the United Nations, agar is merely recognized as “a hydrophilic colloid extracted from certain seaweeds of the Rhodophyceae class.” In terms of its actual composition, agar is mostly a combination of two polysaccharides, agaropectin and agarose, which themselves are complex and poorly-characterized polysaccharides made mostly (but not exclusively) from the simple sugar galactose.8
Unfortunately, the tenting doesn’t work for me. Because of the extra keys at the outer edges, raising the middle edges upwards lifts the center keys considerably, which brings my wrists and forearms off the desk instead of letting them rest. Holding them like that created extra neck and shoulder strain on my part, which is sort of the opposite of the goal. But if you’re not into tenting anyway and want a flat, Alice-split board with an adjustable splay, this works quite well.
