Hi All,

Small crushed marble pieces are the correct form of Boiling Chip, these are at a specific size as they have tolerences for their size when manufactured. They are usually 3mm in size. Perfect in organic reactions.

I have BDH brand of Boiling Chips, which you can get from a good Scientific Supplier.

Cheers,

I dont use the glass beads. Problem if they are spilled.
Unless theyre larger, they go everywhere(roll far because of their shape), are difficult to gather up again.They are harder to see, even if they are coloured, and can cause a dreadful slip hazard.

Much better to use broken crucible lids

Hi All,

The Marble boiling chips that I have are "miniature rocks" @ approx 3mm, there is no chance of these rolling off benches, due to the irregular shape.

I have had the same boiling chips since Uni and I have probably used 20% in total.

Cheers,

Robb.....

Robb, irregular shape, that would be much better. I remember the ones I used ages ago were shockers, as they were spherical. Who supplies them?

We use marble chips also, and the good thing is you keep recycling them.
