I tried this script:

DissolutionChamberRecipe.addRecipe("test", [item:minecraft:stick, item:minecraft:carrot], fluid:minecraft:water * 1000, 20, item:minecraft:golden_carrot);

It does not work, I get this error:

don't use the class directly. use the recipe type(granted there is no examples).
this is the example i tested in dev :

<recipetype:industrialforegoing:dissolution_chamber>.addRecipe("example", [<item:minecraft:stone>, <item:minecraft:andesite>], <fluid:water>*1000, 2, <item:minecraft:dirt>);
