I've used LOS for the first time, and it was kinda fun. But now it's worn out, and it's time to get rid of it. What's the safest way? Down the toilet? Out on the soil? Call a hazmat team?

LOL - Hazmat!

No, you can actually just dump it down the drain. I usually run the water for a minute afterward, too. I dont know if that does anything, but it makes me feel better :)

To dispose of LOS neutralize with baking soda, then you can either dispose down the sink or toilet.

I am pretty sure I remember reading that you should let it sit in a closed container for a few days, turns almost clear in color and THEN it is safe to put in your garden and dump outside. That is what I do anyways. Not sure about putting that in my drain when still active.

It dies after a few days, lol not sure the technical term but it will look almost water like in color .

Good luck,
Marie

Here is one link I found, sounds pretty safe to dump in the drain as is with water....

After you have used a liver of sulfur bath for a fired metal clay piece, how do you dispose of the liver of sulfur? Thanks for your help.

Though liver of sulfur (potassium polysulfide) can be a hazardous substance in dry form (please read this product's warning label), it quickly goes inert with exposure to air and moisture, so the bath can be safely disposed of down the drain. Flush the pipes with water for several minutes afterward. If you don't have access to water in your studio, neutralize the bath with a baking soda solution, pour it into sawdust or kitty litter, let it dry outdoors and dispose of it in the garbage.

Make sure you work with a liver of sulfur bath in a well ventilated area; wear rubber gloves and use copper tongs to manipulate your pieces in the bath; and never add any type of acid to the bath or the gas will become terribly toxic.

Thx very much for the info! Seems to me that since there is acid on our skin, it's a bad idea to let fingers come in contact w/the los in solution w/h2o, and remember to always wear gloves, which you wisely advise.

Going off to read the link now~*~

LOS is an acid. Add baking soda to neutralize. Then you can dispose down the drain. Although spent LOS is not likely to cause plumbing damage. Neutralizing LOS will protect your pipes AND protect the environment.
