Baking powder and snow

I have been playing around with ways of making snow bases for the past two days, the campaign I have been playing in for the past year is on an ice planet called svaard and the final battle is taking part in the snow. So after a lot time I have finally decided to make the snow army I have always wanted, and it's the Dark Angels that get the pleasure of freezing their power armoured toes off.

I've looked at lots of commercially available snow basing material and it all comes in small pots and is rather expensive especially to rebase 130 troops; looking around on the internet I found a video on you tube of someone using baking soda. I had some in the kitchen so tried it out straight away and... it works really well. Just mix a bit into PVA glue and water and it starts to foam up, apply the foam (more watering down is needed) to the base where you want snow and then dip it into more dry baking powder; then allow to dry and varnish to harden it all up, it looks awesome and is easy as anything.

The tanks I dusted in baking powder, blew most of it off then varnished; it gives a nice lightly snowed on look.

I had to take some pictures and here they are.
