thank you! I think i am seeing the same one as you (US SDS, UK SDS) as i didnt find any SDS specific for NZ it doesn't state H411 or H412 warning. it just says "Please read Section 2 completely. If any environmental warnings such as; H411 or H412 are listed in Section 2, please use appropriate procedures when disposing of product and container. Do not put materials into waterways or sewers." I thought that meant, do not dispose of underglazes in waterways or sewers, regardless of H411 or H412 being present or not

hi! i am a new hobby potter so please bare with me im wondering how you all dispose of underglaze water safely? i couldn't find much information on this online currently using AMACO velvet underglazes zinc free and AMACO HF-9 Zinc-Free Clear glaze. in their safety data sheet it says to avoid disposing in waterways and sewers. im reluctant to dispose in my lawn since they aren't very good for the land if some one wants to grow plants on it one day i saw that some people who use water-based paints (Acrylic paints) for arts and crafts use aluminium sulfate and lime powder to filter out the paint from the water and dispose of the paint in household garbage. could this method work for underglazes?
