Having searched for existing issues and through the duplicates I have found this ticket. Resolution "Works as intended". I find it really inconsistent for a Magma block to cause heat damage, glow with incandescent heat and yet have absolutely no effect on snow and ice. I know this has been marked resolved as "works as intended" but are you really sure this should be the intended behaviour?
This is intended behavior, the magma light level is 3, which is not supposed to melt ice, this belongs on the suggestion page not a bug report.
@unknown This is not intended, as Dhranios made it intended last time, one of the moderators have reopened the report.
Can confirm in 1.19
Seriously, on contrary to melting Snow with Magma Blocks l would suggest Snow Layers on top of Magma Blocks converting them to Netherrack, which would compose renewable Netherrack source in Java Edition. Looks like this has happened with Ruined Portals in snowy biomes.
Also simpiler fix you can make with datapacks right now is: file - tags\blocks\snow_layer_cannot_survive_on.json - add magma block there - it'll behave in a similar manner as Ice that is full but can't support snow on itself.
The light level from the "extremely hot" (magma) block is way too low for ice to be melted.
