How long do the H Dupont silk dyes last in my Studio?
Are you wondering about the shelf life of H Dupont silk dyes?
I received this question via email from Chantelle, and I am pleased to say the answer is very good news indeed!
The first step was to contact the manufacturer and their reply is:
-
“there is no limited shelf-life if the bottle is well closed and stored in a cool and dark place”
That’s fantastic news! It’s so great to hear this from the manufacturers.
Over the years, I have had silk painting Students ask me questions similar to this, because they didn’t want to buy silk dyes which had a short shelf-life. I’ve always been pleased to set them at ease by letting them know I have some brands of French silk dyes in my Studio which I have had for 20 years and more.
If you have questions for the H Dupont silk dye manufacturers, pop over to their Contact Us page on the website:

Fill in the form on their page, and they will get back to you:

Let me know how you get on – I found the staff to be very friendly and helpbul.
Happy painting!
Cheers

8 September 2025 – Gracias, Gracias, Gracias!!!!! estaba desesperada por saber la caducidad de los tintes Dupont que guardé desde 2006, para retomar la técnica. Y por saber que había sido de la marca DUPONT y porqué mis números de la carta de colores no coincidían.
Me has ayudado mucho!!!!!!!

Translation: Thank you, thank you, thank you! I was desperate to know the expiration date on the Dupont dyes I’d been saving since 2006, so I could get back to using the technique. And to find out what brand it was, and why my color chart numbers didn’t match.
You’ve helped me so much!
Big kisses from Madrid.
Isabel, I tried to reply to your email, but it wouldn’t go through – I’m so sorry xxx 🙁
