While not with butane or dry ice I have made fresh extracts before with winterized 95% ethanol. Right after cutting off the plant and right back into the freezer for a more old school tech version.
Fairly similar in essence though and as long as you have borosilicate glass there shouldn’t be an issue. Lab glass is worth it 
As far as what you use to blast with I won’t tell you what’s best for you there. The dry ice option to maintain longer contact isn’t an issue if your bud isn’t sprayed or grown poorly. If we’re all assuming it’s home grown, then a live extract with buds that were never sprayed shouldn’t be a issue. Chlorophyll freezes solid at butane Temps. Even if some got in it would winterize out wouldn’t it?

That’s a good question. I’ve never tried to winterize it but I’ve only over soaked it once and tossed it because it was green lol. First time I wanted to squeeze everything out lol but it wasn’t worth it

I’ve never had green bho and don’t want to! Closed loop with a short soak time seems like the best option just cause I know a guy who makes good bho with one he’s booked for about a month usually lol. If it was trim I think a tube would be best just cause the tane would be able to contact everything. By the way ice cream cake is probably the weakest strain I have going! Even in a blast tube the buds get soaked for a good 3-5 mins doesn’t it

I just use a tube. I’m not blasting pounds at a time so I’m not investing in closed loop. This works great for what I need
