What is the ratio to water in an auto engine as a sealer. I have read 2.5% to 5% of capacity ?

Get engine warm and add 1 quart. Did this on a cracked head in a 62 Chevy. Worked great.

Can waterglass be used to preserve eggs ?

If you Google water glass (two words) you will find many references to preserving eggs in water glass for 18 to 24 months without refrigeration. My Dad's family did this.

is it pre diluted or dose it need to be diluted

This product is a 40% solution and can be diluted depending on your application. We do not have application specific instructions so it is up to the consumer to know how to properly apply the product.

Could be used with sand to be hardener with CO2? To make sand core in foundry industries

yes it is a very good hardener.
