### ⭐⭐⭐⭐⭐ Great Product!

### ⭐⭐⭐⭐ Smooth but Surprising: Hydro-Stone Plaster for Candle Vessel Molds
*by L***E on July 10, 2024*

I used Hydro-Stone Plaster for casting candle vessel molds and found it to be incredibly smooth, which made for an excellent finish on my projects. However, it's worth noting that the plaster isn't as white as I had expected. In fact, some pieces had a pink hue after drying. Despite this unexpected coloration, the product still works well for my needs and I will purchase again.It came packaged in a bag and then a box - easy to store in between uses.
