Hello. I am a Korean subscriber. I heard that the melting point of gelatin in silver gelatin emulsion is about 25 degrees. In Korean summer, the temperature rises to 35 degrees Celsius. Wouldn't the silver gelatin emulsion film melt like this? Is there a solution to this?
My experience in making emulsion is that photo grade gelatine melts at 30-35C in water when making the emulsion. But when it is dry on the plate I don't think it would melt if the air is hot and dry. But you need to keep all film cool in a climate like that! If you wanted to pour plates you'd need air conditioning and a cold slab. I'm in Scotland so we don't have any of these problems :)

請問感光乳劑怎麼可以做到不脫落？我試過自己做藍印（cyanotype）乾板，事前玻璃用了消毒酒精完全清潔再塗布，但是曝光後一放到水裡乳劑層就剝落下來了。請指教！
