Hi everyone

Did you know
Rock crystal is colorless natural quartz that grows under pressure in the presence of mineral deposits. Just after the Earth was formed, intense heat and pressure created ideal conditions for forming quartz.

Cheers

The crystals I have put up are of Clear Quartz.

They show the pointy crystal stuctures well. They have flat sides, long crystals and are very clear. The middle picture is of a cluster but it is still pointy and with a flat bottom.

A few days ago I made another crystal it took 3 days and it is still growing this is my crystals now.

Hi everyone.
My crystals keep growing!!
They are looking pretty big and crystal clear now.
They show the shapes of each crystal very well and stick out in all directions.
Cheers

Hi everyone

Here are some of my crystal models and some of my rock crystals

This is an octahedron made out of magnetic sticks and balls I made.

Hi everyone
My crystal didn't really work so I am going to use my second sachet to make a new crystal.
Did anyone else's crystal not work?

Bradley21. Crystals day 6

Hi Everyone!!
My crystals are HUGE!!!!
Look at my pictures.
If you want to see them full size click on the picture.
MY crystal in the discovery tube did not work. The plastic rocks didn't form crystals either. But my tree was successful and it looks pretty cool in real life!

Here is my crystal today

On the way home from town on Saturday we dropped in to Gemtree to fill up with petrol and I asked Carmela the owner of Gemtree about crystals in the area that I could find crystals. She said I can give you some samples so she went and got me three crystals.

This black crystal is called
Tourmaline. It is found at Harts Range. It has long, flat surfaces.

Thios crystal is clear Quartz it crystallised directly from magma or is deposited from silica bearing solution in veins. It has a crystal shape as it has flat surfaces and edges.

This crystal is man made and was done by putting the rock into a big barrel with sand and spun round and round for 6 weeks to get it that smooth.

Here is a time lapse video of mono ammonium phosphate crystals, with a seed crystal, growing over 15 hours approximately.
The pictures were taken every 30mins.

Hi everyone

Here is my rock crystal experiment and i have some photos

George21

I took a time lapse of jelly crystals dissolving in hot water.
The x10 was really good but the x60 was a bit fast.

George20

Here are some photos of lesson6:
1) Preparation
2) Crystal after 1.5hrs
3) Crystal after 24hrs, x10
4) Crystal after 24hrs, x60
5) Crystal after 48hrs

Bradley20. Dissolving Diagram

Hi Everyone.
If you don't completely understand the formation of a solution, here is a diagram to help. My diagram will show you how particles of sugar are soluble in a liquid substance
and thoroughly dissolved to make a solution. To aid dissolving I increased the temperature of the water and stirred. I could also have crushed the particles some more to aid dissolving.

Bradley19. My Crystal growing day 3 under the microscope

Hi Everyone!!
Here are some pictures I took using the microscope. The crystals were from the bottom of my jar containing the rock, and they were the same structures as the crystals shown in my previous posting.
Cheers
Bradley
