Builders sand cooking instructions

[vpacalypse]

Bought 2 packs of builders sand.

how long do i keep them in the over? what gas mark?

or will simply placing them next to a radiator for a while do the job?

Well I'm not an expert, but given no one else has replied yet, I'd say since the idea is to dry the sand out, I'd suggest any temperature above 100 degrees C for a few hours should be sufficient. And putting it in a container which can withstand those temperatures would also be advised

That sounds seriously extreme, i'm gonna plant a bag outside a radiator for a while

If you're talking about sand to put in a speaker (which I assume this is for), I'd follow the prof's advice and bake it in a low oven (over 100C) to ensure it's absolutely dry - spreading it out on a metal baking tray, or in one of those disposable foil containers should do, and leave it in there for about an hour or so and then leave to cool...

Use the sand to repair a patio or similar. Buy some cat litter, seems to be the popular choice recently, it's already fully dried and probably costs less than your sand. But, subjectively, I'll bet there is only one true path and that it costs the earth to follow it.

If I do this, I'll rank it in the top tier of the most ludicrous things I've done to date.

Hey hun, what you making...I'm baking sand...what?!

or buy 'kiln dried' sand from Wickes and bypass this stage.

+1 (B&Q in my case).

Really, I didn't think it was that extreme - I must lead a more exciting life than I thought

Remember, the purpose is to ensure there's absolutely no water left in the sand, otherwise this will (eventually) rust your stands. I'm not sure planting the bag next to a radiator is going to cut it personally, but it's up to you.

IMO a radiator at distance is not going to replicate the heat of a kiln, that's what you need to aim for, for the reasons the prof says.

+1 to that.

Kiln dried sand - the sort you use for jointing paving is the cheapest thing (I have a couple of sacks at home for a new patio), it's really, really cheap - I've seen it for <£5 for 25KG!

I bought a 15kg bag of play sand from Argos not too long back for £2-99.The OP thinks it's extreme to dry it out in the oven? At the time I bought it the oven wasn't working, so I got a seriously big old saucepan and used the hob! Constantly stirring it around with the help of a mate, and IIRC took around one and a half hours. Now that's what I call extreme!

Have you tried Rus SANDrews? I'm sure he could sell you some magnetically shielded sand/magic beans!

i've dried sand in a trough on top of a radiator in the past. Just leave it a few days and it will be totally dry.
