Can crushed recycled glass (sold as an abrasive for sandblasting such as be used as a silica sand alternative when making carnivorous plant soil mix? Would possible trace amounts of other elements (such as to tint the source glass) be an issue? Has anyone done this?

Where do you get your sources of silica sand for soil media?

Not too sure about crushed recycled glass but, a lot of people use pool filter sand which is usually #20 quartz Silica Sand but, #20 is pretty fine sand. Most recommend a #12 coarse silica sand which can be hard to find depending on how much you need and where you live. - Sand is cheap but, expensive to ship - can be found on ebay & amazon. Horticultural perlite is a good but not perfect alternative to silica sand.

It should be perfectly fine to use. I have a couple of friends that have used crushed glass in their CP mix and saw no I’ll effects and had good results.
