Hi! I know of Daisy - she's the radness, and is the co organiser of the Melbourne Ceramics Market - which from day 1, was just bonkers - we're talking people in a warehouse buying ceramics like it's christmas eve - there's queues, you're shoulder to shoulder with other people buying stuff - it's so much fun. That was in...2017! I volunteered at one of the first markets, and it's just gone strength to strength since then, and they're doing markets for seconds and emerging makers now.
Ok, so, disclaimer time, like every time I do these things*** - you are not going to be making what you see tomorrow, because Daisy has been doing this style for a Very Long Time, and whatever she does now is her own.
FYI: I never have that conversation with folk of "so, tell me how you do this thing" but more "I'm doing this thing, and coming up against x, y, z, what advice do you have for me?" like I did with MC.
The options that I'm giving you are based on my best guess, along with techniques and ideas that I've picked up. I'm researching color layering right now over yonder, and need to add to that. I'll post mine, because that was underglaze and cone04, and that, I can break down for you. You don't mention what cone you're working to - I initially thought it was cone 6 with Daisy, but it looks like she might be using a locally available commercial glaze, which is cone 10.
I'm pretty sure that Daisy is working like this: make work, bisque (or even single fire) then the colouring is created by layering glazes. The reason why is because she's doing production - she ain't got time to be sitting around pfaffing with brushing on slip, then underglazes, then a glaze over the top. Because Daisy is doing her own thing, and is not a beginner, she's probably got a base clear that she's added various stains/colorants to. If you check her partner in crime with the ceramics market, Clay By Tina, it's way more obvious in her work that's its just glaze, because there's no way you can do what she's done to the same effect with an underglaze and clear over the top.

So, what I think Tina has done is she's holding the plate as you see it - vertically, and pouring each glaze color from the middle of the plate down, which is spreading out slightly as it's reaching the bottom.
If you look at the top pic you've posted, you'll see that there's also that "waterfall" type effect of a glaze over another - if you want that to the extreme, that's where u/oldforgecreations kicks in with his use of rutile in the overglaze to give you floating blues.
So, going back to the Daisy cups - it looks like a dip into a white satin glaze as a base, then she's pouring glazes (possibly thinned down quite a bit, as it's coloring, not coverage that she's going for) over the top. If you look carefully at these plates: https://www.instagram.com/p/CTDrhUIJa7m/
You'll see that in one, there's the exactly pink tongue shape that tina has in her glaze only work, which reinforces that these are glaze only.
maybe I need to take that cone 6 guess back, as thats looking an awful lot like rockmelon spangle gloss: https://www.instagram.com/p/CMNn-HJA46a/
https://shop.walkerceramics.com.au/EVG6096.1/Rockmelon-Spangle-Gloss-Glaze-1260_dash_1280/pd.php (an aussie posted work in this glaze, I think to r/pottery about 6 months ago, which is how I remember the look as the test tile doesn't give you much to work with).
Greg Daly is the master of layering glazes - I did a workshop with him, and if you go through this carousel, you can see the plate where he's applying glaze with a jug. Check the glaze layers - just looking at the colour changes, you can see he's about to apply LAYER NUMBER SEVEN!.

This book of his is hard to track down as it's out of print, but great: https://www.amazon.com/Glazes-Glazing-Techniques-Greg-Daly/dp/0713642769
So if you have a university/community tertiary education type place, it's worth seeing if they might have a copy you can borrow/have a picnic at the library with :)
