Using Tin Oxide and Zircopax together produces a better white and has much less tendency to crawl.

Notes

*This is the standard G2934 matte and G2926B glossy blend (which produces a satin matte). We have added Zircopax and tin oxide added to opacify it to produce a white.

The mix is being used because pure Zircopax tends to cause crawling.

Notes

*This is the standard G2926B transparent glaze recipe with Zircopax and tin oxide added to opacify it.

The mix is being used because pure Zircopax tends to cause crawling.

For dipping we use the same method as for the G2926B base.

For a 500ml jar of brushing glaze we blender mix 340 powder, 440 water, 5 CMC gum and 5 Veegum.
