I'm wondering how vendors who use pure soy wax can get their tarts looking and staying as nice as parasoy / paraffin. I've been testing for nearly one year using all soy blends (GB 444, Eco Soya PB, and Eco Soya CB in different ratios depending on what I'm making), and they always end up losing their smooth texture and creaminess and become crumbly.
I've seen some people on various forums stating that this is just the nature of soy, but if that's the case, how do these all soy vendors end up having such beautiful looking wax?
Any tips would be highly appreciated!
