Balancing the flow of a lamp with pickling salt

[Todd Miller]

I have a few lamps that are low on fluid and I'd like these

to be donor/experimentation globes.

I know I can use distilled water to top them off and

pickling salt to change the specific gravity. 

One globe (52oz) is maybe 5oz low and the 32oz will

take less than a shot (1oz) of distilled water.

I'd like to add the salt to the water, but at what rate

of saturation ?

Can I bring the lamps up to temp and then just slowly

add the grains of salt and see what happens ? or, do I

make a solution of dissolved salt/water and replace a few

ounce's at a time ?

I'd rather go slow than over do it.

I used to get my propylene glycol from like a farm animal veterinary supply website

[Todd Miller]

It's pure propylene glycol 100%

They use this for cattle or farm animals, 100% mixture.  They have it in stock

locally so I will pick some up and dilute with distilled water accordingly. I think it's

30 parts glycol to 70 parts distilled water.

I got mine from Ebay but as others have said agriculture shops sell and probably in bulk so would probably be cheaper
