Re: Tissue infiltration, embedding & casting of wax blocks..
I see that you do not surrender, that's good. In my opinion the sample pieces were too big and did not manage fixing and dehydrating. My sample pieces were not larger than 3-4mm. After fixation and dehydration through a series of alkochol the sample lose their chlorophyll and become almost transpar...

Re: Tissue infiltration, embedding & casting of wax blocks..
Had a quick go at the tiny stem-like xs today - the new blocks are proving very difficult to get a decent set of sections from - again! Anyway, here's a couple of rather unclear pictures of 'something' found in my first (failed) set of blocks - the ones that were mushy! I think this is a tiny stem -...

Re: Measuring Worth
I have nothing useful to add. But I feel it would be remiss of me not to point out that the title sounds a lot like a hypothetical English town, as might be used in a period movie. "And this is our new vicar, Mr Peter Brown. He's from Measuringworth." ;) Hah - could even be a village in the perilou...

Re: Oedogonium zygote
Your super pictures have made me want to have a go at stacking 'properly'. Can you give any tips regarding the choice of focus levels for the stack - do you use a series of for example x-number-of-equidistant-focus-levels, or do you perhaps choose particular parts of the subject (moving of course in...

Re: Tissue infiltration, embedding & casting of wax blocks..
Hi all, quick update... I now have a set of 9 new wax-blocks containing stem-pieces from 2 Chrysanthemums, a white one and one of those unusually- green ones. :) The processing this time around went well and I'm reasonably optimistic about this new attempt.. Tomorrow I'm hoping to get the time to st...

Re: Tissue infiltration, embedding & casting of wax blocks..
gekko & 75RR, thanks for your help - It is definitely worth a try, it does as you both say make sense... Sectioning a cell anywhere less than say 50% of it's thickness sounds like a recipe for trouble? I'll start at about 15µ and work slowly down to maybe 8µ and see how it goes! Thanks again you two...

Re: Tissue infiltration, embedding & casting of wax blocks..
Hi Mrsonchus, If you find the sections crumbling as they are being cut, then you may be able to remedy this "disastrous"situation by giving the block a spray with ladies hair spray. If you cut a hole about the size of your wax block in a piece of paper and places this over the block this will prote...

I'm back - but only with some mediocre images! :( Well, I started a new batch of Chrysanthemums from scratch - the incubator was settling at 68 deg on it's own without intervention from the digital thermo-switch - all good I thought. It had happily kept my wax liquid all day and I was confident that...

Re: Help with identification
Many thanks, John, for your input. I tend to agree with you in that all the pollen that I've seen is spherical or nearly so, and those are quite flat and, therefore, what you say makes sense to me, despite my ignorance. Perhaps they are some kind of spore. Had a thought, whereas pollen is, as far a...

Hi Gekko - nice images for sure. I've looked at lots of pollen under the 'scope since I started and I really don't think these are pollen grains... The tube-like structures don't look like pollen-tubes - they look far too rigid in their shape and direction of growth to me. Pollen tubes tend to be pr...
