Soda blasting have I got the wrong stuff
balidey - 8/10/10 at 04:40 PM
i think I know the answer to this, but I need confirmation.
I want to try out Soda Blasting. So I sent my little sister (we shall call her Dippy because she is) to the Cash and Carry with the instructions to
get 'Baking Soda, not bicarbonate of soda'. Not sure if they are actually the same, but I definitely said Baking Soda.
She has come back with a bag of Baking Powder.
Now this feels very fine, and I'm sure its too fine for blasting, its like flour (not actually opened the bag yet incase I can send it back).
So, is Soda actually different to powder? Is soda more granular?
Your help please.
next question, do cash and carrys ever take stuff back?

I used bicarbonate of soda for a bit of blasting once, worked quite well. I use it for washing my hair (tablespoon in a cup of hot water) and
household cleaning.

Baking soda is the same as bicarbonate of soda. Baking powder is baking soda with an acid added. Both are typically powdery.

do it outside.
I thought I'd have a little try inside once...bad idea.

Great, just what i wanted to hear, both powdery. Google results were all about how to use them in baking (typical 
) but no mention of their
consistency. I pressumed that as its for blasting it would resemble salt...... theres an idea I can try with the blast cabinet

You missed,
Cover in vinegar,
Soak in molluscs,
freeze for 24 hours (flywheels prior to fitting the ring gear)

Don't want to use sand. Can be nasty.
I was suggested crushed glass or polymer chips for proper blasting, but thought I would try out the soda after seeing Thunderace's post, some
impressive results there.

Not convinced a lung-full of crushed glass is safer than a lung-full of sand.

Neither would do you any good at all, but inhaling the silica dust you get from using sand will give you
Silicosis and you absolutely don't want that.
