300ml total split between two jars.

that way if nothing comes out i can combine both jars into one, pour in some good old table salt and salvage the results in one large jar while still leaving room for the solvent and air at the top to spare so it doesnt slosh everywhere.

thank you for the information cave painting, looks like ill do going for about 60-70g for each probably go for 70.

by the way, i dont know if it makes a difference, but i think it would be wise to dry out the magnesium sulphate in an oven before it is placed inside the jars, dont know why just some idea that if i put the stuff in and its already attach to water it wont attach to the molecules inside the goop.

dont know if that will change the numbers.

thank you.
