Review: BEST FBS (Full Body Silicone) Doll Powder To Use - BEST FBS Powder Anywhere! I'm known for researching everything and the right dusting powder for my silicone dolls is no different. There are many different powders sold on the net (most outside of the USA) under different names and they give you a few grams, normally this product is blended with different ingredients that are often not even listed) for a very high price! We all know that silicone dolls are expensive art dolls that are pristine and as close to a lifelike baby as you will get in a doll, so we are all careful with the products we use on or around them. Silicon Dioxide is bought directly from the laboratory, so don't expect Prime Delivery but know that it's worth the wait and the perfect complement to your silicone dolls. I use Anne's Giverny Kabuki Large Bronzer Brush Loose Powder Foundation Makeup Brush for application. It comes with a nice mesh cover for storing and I keep these products together. No clumping. No residue left on your doll/s and no uneven coating/powdering. I can't say enough good things about it. It works perfectly. Like other silicone powders or even baby powder, be careful not to inhale this and it should be kept away from children and pets. You can hardly tell that it's on your doll at all and it doesn't take much. I go over my dolls twice and it lasts a long time. I recommend it to all FBS (full body silicone) doll artists and collectors as the one go-to product that will do everything you need it to at far less cost than you can find anywhere else. Buy with confidence. Highly Recommend.

## Questions & Answers

**Q: can this be used to make hydrated silica?**
A: It can be used to make hydrated silica, - but it is quite an involved  process, we sell silica gel in bead form that can be made into a neutral, hydrated silica much more easily by crushing and adding water.

**Q: Is this food safe?**
A: There are three grades
1) Pharmaceutical
2) Food
3) Feed

As you might expect pharmaceutical is the most expensive
