Re: pH Charts

It's a pleasure . Worth the time to make a resource if it can be shared.
I have taken from Chemtalk over the years so happy to give back what I can.

Re: How to post a picture on Chemtalk

OK, just discovered that the Attachment size has a limit of 500Mb . So you can scale pics bigger than 800 pixels if the pic doesn't have too much detail in it . Maybe up to 1200 pixels on the long side . But for the most part 800 pixels will cover most Pictures. This forum must have a file size limi...

Re: 3D Printing

Nice work MrsCooper . \:D/ wondering what 3D design program you are using ? I looked at Fusion 360 and my brain exploded so gave up . Then tried Google sketchup.That seemed really hard work and wasn't the right tool . Tried Tinkercad and although its a Kiddies program , it suits my ability :whistlin...

Re: pH Charts

Wow! They look great! We have the universal charts that come with the indicator. What will you use the other charts for? I don't know that I've ever needed to know the exact colour range of the other indicators like that. Thanks Rosalie , It's just something the Chem teacher has always asked about ...

Re: Banned from 1 NOV

I thought you were talking about trying to convince them that we could still use them in Science . That will be my problem . The email response you posted last week is the only written statement to actually suggest its OK , even then, it's a bit vague. Did you watch the online seminar about it? No ...

Re: Banned from 1 NOV

No, as in convincing them that we can't be using the remaining plastic bowls and plates at functions/parent info nights etc. (to be discarded after one use). I've just had a follow-up chat with the person higher up and the response this time was a lot less dismissive than the initial conversation l...

Re: Banned from 1 NOV

Has anyone had trouble convincing "higher up" that this is actually a thing and that schools are not exempt? Sorry not quite understanding your question Rosalie . By the looks of the highlighted text in your email , it looks like we are OK to keep using plastic things so long as we will w...

How to post a picture on Chemtalk

I noticed some are attaching word docs in an attempt to attach a picture , so I thought I'd do a quick tutorial . First off , there is a size limit to pictures . They must be no larger than 800 pixels on the longest side. You need to resize pics in windows "Paint" or other picture software...
