We Chinese call "Silk Touch" (丝绸之触) as "Accurately Picking" (精准采集).
I found this bug feature on a video:
https://www.bilibili.com/video/av67079443
Watch from 1'28" to 1'51".
This is what she said:
"3. Breaking ice with Enchanted Books"
"I believe that this feature isn't be known by most of long-experience players. All we know the features about ice, it will become to water by picking with hand only, You can only use pickaxes enchanted Silk Touch to get full ice block. However, if you pick ice with an Enchanted Book stored Silk Touch, it will drop ice item, and produce flowing water, too. Really: 'I want 'em all' ?"
Thank you for your report!
