Notes

(Richard Willis)

A tree resin used in over-glaze recipes to augment the recipe’s adhesiveness without altering its formula and thus desired effects. Few over-glazes, when applied to already matured (i.e., non-absorbing, glassy) surface, will stick uniformly while drying and heating up, resulting in flaking, peeling, curling and the likes before reaching their melting/fusing points. Arabic Gum, as with CMC, can be mixed with the glaze slurry or painted directly onto the already glazed surface to be second-glazed (i.e., over-glazed). To prepare the gum, dissolve 50 grams per liter of water, let sit until totally dissolved, heat to a slow boil until it reaches the viscosity desired, then either paint directly onto piece or mix slowly, while stirring, into the glaze slurry in portions of 25 cm³ of gum to each liter of glaze slurry. To save prepared gum solutions, add 2% straight “formol” (formoline) — an industrial dilution of formaldehyde.
