I was talking to someone last week and I offered to bring in some washing soda (aka sodium carbonate, not sodium bicarbonate). It is used as an electrolyte in electrolysis tanks as well as for electrical engraving of steel.
I put a reminder in my phone to bring in the washing soda, but NOT to whom I was going to deliver it to.
Was it you?
Please let me know, if so. I’ll be at DMS some time after 8pm tonight (Thursday). I’ll have the stuff in the bag, and a slightly befuddled expression on my face…
