No equipment or knowledge. Just an interest in a new hobby. So DIY-ed my kids' pottery wheel. Started with 150 grit on a random agate from a beach and its going great!

Souvenirs from far off lands sent by lovely strangers

My sister recently attended the BTS concert in Munich and met her friend group (army is what the fanbase is called, I guess?).

I do not know them. They do not know me.

We have never met, talked or interacted in any way.

But my sister jokingly mentioned that all I am interested in are the rocks she finds in Munich.

And now I have this amazing collection sent by complete strangers from different parts of Europe.

Pebbles they picked up around them or in their travels. Labelled and packed to send to me specially.

Nobody asked them to. They did it on their own, just for me.

It is enough to make a grown woman cry.

Apatite crystal chips that pushed me into a rabbit hole. The one mineral that led to advanced life forms on earth, and I thought it's just a pretty gem.

Revealing the shine of this Stephen Green Lamberth stoneware jar found in Gujarat, India. Water, paper towels and elbow grease. Any advice?

1820-1850s Stephen Green Lambeth salt-glazed ceramic "glass-lined" jar recovered from an old haveli in Gujarat. I was told you guys may be familiar with these types of jar. What is the story behind it?

1820-1850s Stephen Green Lambeth salt-glazed ceramic glass lined jar with a wooden stopper. Recovered from an old haveli in Gujarat, India. It's my first antique find, so curious to learn more about it. Should I clean it up or leave it as found?

My first vintage find! A 1960-70s handcrafted ceramic lamp/vase with traditional cutwork of Khavda pottery from Kutch, Gujarat with Art Deco inspirations. Recovered from an old Gujarati haveli.

Laterite, possibly bauxite and quartz found on a forest trail at North Goa

Bauxite and laterite are mined in the hills around Goa. Laterite is a common construction material in old traditional houses and churches.

We were on a forest trail at a resort in North Goa. The pathway was covered in black basalt rocks along with these reddish rocks and quartz. The pathway was also lined with brick-like blocks of laterite.

Colourful rocks found at low tide in Daman

Most probably the red ones are rhyolites. The black one is basalt. A potato rock. One of them has crystals embedded on it.
