For those of you who prefer not to use a microwave we can now recommend that you use our 600ml super strong Pyrex beakers for making colloidal silver. The beaker comes with a protective gauze and can be used on gas or electric hot plates.

Please read the safety tips before first use.

Safety tips.

Rapid temperature changes will even cause thick tough Pyrex to break!!

Please take care when handling hot liquids.

Safety Glasses are recommended.

Heating on an ELECTRIC hot plate.

Simply Place the beaker directly on the hot plate with the cold water. Switch on the hot plate and bring the water to boiling point. Switch off and wait a few minutes before putting in you Silver Electrodes (other wise extra boiling will occur).

Heating on an GAS hob / burner.

Place the gauze on the hob / burner first.

Place the beaker directly on the gauze with the cold water. Switch on the gas and bring the water to boiling point (do not use to high a glass flame, that passes the edges of the gauze). Switch off and wait a few minutes before putting in you Silver Electrodes (other wise extra boiling will occur).
